In this post, I comment on Renewable Fuels Association President Bob Dinneen’s opening statement, “America’s Energy Future Is at a Crossroads,” at this week’s “Cellulosic Ethanol Summit” in Washington, D.C. Dinneen’s remarks are indented; my comments follow.

“Ethanol, and America’s energy future, is at a crossroads.  Either we will continue on a path toward greater energy diversity and security by expanding the current Renewable Fuel Standard to motivate investment in new cellulosic ethanol technologies, or we will succumb to the nattering nabobs of negativity who are seizing upon every unfounded fear to thwart the worldwide movement toward biofuels, leaving us evermore dependent upon petroleum and its environmental and economic consequences.

Comment: Energy “diversity” is not an end in itself. We could, for example, diversify America’s energy portfolio by mandating greater use of horse-drawn carriages, sail boats, and water wheels. Claims that oil dependence threatens American security are wildly exaggerated, as Jerry Taylor and Peter Van Doren explain here. The worldwide “movement” toward biofuels is a creature of political subsidy and mandate–not market-driven. Dinneen’s policies would leave farmers “ever more dependent” on government largesse.

“Some here might think the choice is obvious.  It is not.  Well-funded opponents are engaged in a coordinated effort to protect the status quo.

Comment: Government meddling in energy markets is the status (statist) quo, and the well-funded ethanol lobby seeks to protect it.

“Some might think this is just about food vs. fuel, and the wildly exaggerated claims that grain-derived ethanol is driving up consumer food prices.  It is not. 

Comment: Dinneen speaks as if food v. fuel issue were a made-up issue. Many experts not known for their fealty to oil companies view the potential adverse impacts of biofuel policies on global food security as a matter of serious concern. Such experts include the International Trade & Agriculture Policy Council , the OECD’s Round Table on Sustainable Development, the UN’s World Food Program, agricultural economist C. Ford Runge , environmental guru Lester Brown, and columnist George Monbiot. The rising cost of food, due partly to U.S. and EU biofuel policies, is making it harder to feed the world’s hungry people. The risks to global food security will increase as more and more grain is diverted from food to auto fuel.

Even in the USA, the potential of biofuel policies to fleece consumers is nothing to trivialize. Corn today sells for $3.57 a bushel compared to roughly $2.00 a bushel in 2004-2005, in the pre-mandate era. Other factors, such as rising petroleum prices and surging demand in China, contribute to today’s high corn prices. Nonetheless, ethanol policy is probably the biggest factor.

Corn, after all, is a feedstock for hog, poultry, beef, and dairy farmers. Corn sweeteners and syrups are widely used in food preparation and processing. Rising corn prices also put upward pressure on wheat and soybean prices, because all three grains compete for land and customers. Food prices are rising faster than the overall inflation rate. This is no accident, comrade Dinneen!

“There are groups amassing to slow the drive toward cellulose as well, full of misinformation and distortions about land use, deforestation, water use and infrastructure costs of cellulosic ethanol.

Comment: Again Dinneen trivializes legitimate concerns. A new study by the National Research Council cautions that “greater cultivation of crops to produce ethanol could harm water quality and leave some regions of the country with water shortages,” reports the New York Times. Is NRC also just a mouthpiece of Big Oil, like Lester Brown and George Monbiot?

Cellulosic ethanol may one day be cheaper than gasoline. Currently, however, the capital costs for a cellulosic ethanol plant are three to five times greater than those of a corn ethanol plant. And even with today’s ethanol glut and declining ethanol prices, and oil selling for more than $80 a barrel, regular gasoline is still cheaper than corn ethanol when the latter’s lower energy content is taken into account. Even today, corn ethanol could not compete without the 51-cent tax credit refiners receive for every gallon of ethanol they blend into the motor fuel supply.

“The insidious campaign being waged today has very little to do with the feedstock for ethanol, and a great deal to do with the loss of petroleum market share that will occur if we are successful.  To our opponents, there is no good ethanol or bad ethanol; there is only ethanol, and it’s all bad.  Within the ethanol industry, we must not draw meaningless distinctions between feedstocks either; we must propagate the message that all ethanol is good; it’s all better than petroleum.

Comment: This is commodity fetishism. Neither ethanol nor oil nor any other commodity is good or bad in itself. Commodities are good and bad relative to consumer preference, and markets evaluate commodities at the margin, not as a whole. 

“We have seen this kind of coordinated offensive of mistruths before.  Indeed, many of the same groups fighting biofuels today are among those who just a few years ago sought to discredit scientists focusing the world’s attention on the growing crisis of global climate change.  Today, the Nobel Prize is awarded for awakening the world to the reality of global warming, and companies take out full page ads extolling their efforts to improve their ‘carbon footprint.’

Comment: If Al Gore frightens people into believing sea levels will rise 20 feet in our lifetimes because cars run on petroleum, that will build support for a bigger ethanol mandate. So heaven forfend that anyone–for example, a British High Court judge, obviously another flunky of Big Oil–question Al Gore’s doomsday scenario.

“All ethanol, indeed all biofuels, are in this fight together.

Comment: Rah, rah, sis boom bah!

“We all need to respond to the hysterical claims about ethanol.  We need to enlighten those that believe you can have food security in this country without energy security.  We need to remind people that rising petroleum costs have a far greater impact on consumer prices, including consumer food prices, than a modest and much-needed increase in the prices farmers get for their products. 

Comment: Energy prices affect food costs. But government manipulation of the demand for grain affects food prices more directly. Besides, the deliberate merging of the food and auto fuel markets can make both food and energy prices more volatile. A bump in petroleum prices will inflate grocery bills, even as a drought-induced shortage of corn will increase consumers’ pain at the pump. 

“And we need to educate people about the technological evolution occurring in the ethanol industry today, where more efficient energy resources, water recovery systems, process technologies and new feedstocks are leading toward a far more sustainable energy future for all of us.

Comment: Educate away! And, while you’re at it, please tell us when cellulosic ethanol will be able to compete with gasoline without government handouts or mandates.  

“Are there legitimate questions that need to be discussed about the efficacy of biofuels?  Of course.  If there weren’t, there would be no need for conferences like this.  But we can’t allow the momentum toward a more sustainable energy future to be slowed or derailed while we count the angels on the head of a pin to dissect every conceivable shortcoming that the marketplace has yet to resolve.  We ought to recognize that renewable fuels are going to be inherently better than fossil fuels and encourage investments in these technologies as soon as possible so that markets can start making them more efficient.

Comment: “We ought to recognize that renewable fuels are going to be inherently better…” How do we “recognize” something that hasn’t happened yet? Also, markets do not determine what is “inherently” better but what is better relative to consumer preferences under ever-changing market conditions. Again, Dinneen preaches commodity fetishism.

“We did not move from the horse and buggy to the turbo charged E-85 Saab Biocar without first going through the Edsel.  But it’s a good thing we didn’t stop Henry Ford from mass-producing the ethanol-fueled Model T until automobile technology was perfected.

Comment: Huh? The Edsel was a bridge to the E-85 Saab Biocar? Why not a bridge to my gas-guzzling Ford Expedition? The Edsel was an object lesson in the fact that experts can fool themselves about what consumers want. Dinneen is so sure “we” want ethanol that he believes Congress should force us to buy it. But wait a minute, if ethanol is the great bargain Dinneen claims it is, then no mandate is necessary.

As to the first Model Ts running on ethanol, Dinneen misses the obvious. Ethanol-fueled cars are the auto industry’s failed past. Why suppose they are the industry’s bright future? 

“It’s a fact that the carbon footprint of ethanol is good today (grain-derived ethanol provides a 21% reduction in GHG emissions with current technology and existing feedstocks) and will only get better with second generation technologies and new cellulosic feedstocks.

Comment: This 21% figure probably assumes that the electricity to run the ethanol plant comes from natural gas, nuclear, or wind, and that the ethanol plant is located near the point of sale. Under different assumptions–the plant is powered by coal and the ethanol must be trucked from Iowa to California–ethanol’s carbon footprint is about the same as gasoline’s and maybe bigger.

More importantly, as climate policy, ethanol mandates are woefully inefficient. According to the OECD Round Table on Sustainable Development, biofuels might displace 13% of petroleum by 2050. That would reduce energy-related CO2 emissions 3% below baseline projections. The cost of obtaining these reductions is very high—”well over $500 per ton of CO2 equivalent for corn-based ethanol in the United States, for example, with other researched countries not performing much better.” Five hundred dollars per ton is about 54 times as expensive as what Yale University Professor William Nordhaus, the doyen of climate economics, considers an “optimal” carbon-reduction policy. It’s also about 10 times higher than carbon permits would cost under Lieberman-McCain Climate Stewardship Act, in 2030.

“Conversely, the carbon footprint of oil is bad today, and getting progressively worse the further we have to go in our quest for oil reserves, the deeper we have to drill and, certainly, with each gallon of petroleum derived from tar sands we must utilize to meet the ever increasing demand for motor fuels.

Comment: Yes, but that’s life until someone invents a motor fuel that outperforms petroleum at a better price. That hasn’t happened so far and there’s no evidence it will happen soon.

Consider the European experience. Due to Europe’s high motor fuel taxes, gasoline in several EU countries costs more than $7 a gallon. Gasoline taxes are implicit carbon taxes. Europe taxes gasoline at rates of $200 to $300 per ton of carbon dioxide, and has for many years. Yet where in Europe is the miracle fuel to replace petroleum? Where are all the zero emission vehicles? Europe is not one mile closer than we are to achieving a “beyond petroleum” transport system. On the contrary, EU transport sector CO2 emissions in 2004 were almost 26 percent higher than in 1990.

“Oil companies pretend to be comfortable when ethanol is just a blend component in gasoline.  But given today’s economics, with oil surging past $85/barrel and ethanol priced significantly below gasoline, it remains a mystery why consumers in many parts of the country are unable to find ethanol blended fuels.

Comment: Bob, if you really think oil companies are colluding to keep E-85 off the market, why not come right out and say so? Maybe it’s because Federal Trade Commission investigations repeatedly fail to back up allegations of even subtle forms of market manipulation.

The paucity of E-85 dispensaries is actually no “mystery” at all. In testimony before Congress, Sonja Hubbard, representing the National Association of Convenience Stores and the Society of Independent Gasoline Marketers, observed that converting a service station to sell E-85 and installing an E-85 dispenser “can cost upwards of $17,000.” That’s a hefty chunk of change for a small business. Thus, the slow pace of E-85 conversions “is not due to animosity towards an alternative fuel and it is not due to limitations imposed by our suppliers. Rather, it is because consumer demand for the product is insufficient to justify the cost of the investment.” Hubbard continued: “Trust me, my fellow NACS and SIGMA members and I will make E-85 pumps available when the market calls for it.”

“Angst in the oil patch has been raised to new heights as Congress contemplates a 36 billion gallon Renewable Fuel Standard that provides a certain market for 21 gallons of cellulosic ethanol and moves ethanol from a blend component into a significant alternative to gasoline.

Comment: There should be angst everywhere when Congress tries to pick winners and losers in the marketplace, and decides to hold consumer preferences hostage to a Soviet-style quota system, which is what, in essence, a “renewable fuel standard” is. 

“But the angst begs the question, ‘If not biofuels, what?’  ‘If not now, when?’  These are the questions Congress must answer.  And we must demand an energy policy that promotes a more sustainable energy future.  We must have an accelerated and expanded RFS that motivates investment in cellulosic ethanol while providing a strong foundation for existing production to continue to grow.  We need this now.”

Comment: A “sustainable” energy system does not require ever-greater subsidies and mandates to sustain. Commentators already describe the ethanol boom as bubble created by political meddling. Moreover, a “sustainable” energy system does not threaten to crowd food and wildlife off the landscape. Economist Richard Rahn succinctly explains why ethanolism is ecologically unsustainable:

“If all the U.S. cropland (371 million acres) were planted in corn to produce ethanol, it would provide 111 billion equivalent gallons of gasoline, but Americans currently consume more than 140 billion gallons of gasoline. So, if Americans imported all of their food (or starved to death), they still would only attain 80 percent of their gasoline needs if it had to come from domestically produced ethanol.”

Congress's apparent lack of activity since coming back from the August recess threatens to be replaced by a feverish amount of activity. Rep. John Dingell (D-Mich.), Chairman of the House Energy and Commerce Committee, has released his plan for a carbon tax. It would put a 50 cents a gallon tax on gasoline and a tax of 50 dollars per ton of carbon dioxide on coal, oil, and natural gas. As my more expert colleague, Marlo Lewis, reads the proposal, the gasoline tax and the carbon tax would both be levied on gasoline, so this adds up to roughly one dollar per gallon of gas.

 

Dingell and Rep. Rick Boucher (D-Va.), Chairman of the Air Quality Subcommittee, have also released a white paper on cap-and-trade schemes to reduce greenhouse emissions. They state that their goal is to enact a cap-and-trade that would reduce emissions by 60 to 80 per cent by 2050. Dingell at least supports both his carbon tax and cap-and-trade.

 

Over in the Senate, Majority Leader Harry Reid (D-Nev.) announced that he hopes to be able this week to appoint conferees to negotiate a deal on the Senate and House anti-energy bills passed this summer.

You Win Some and You Lose Some

by Julie Walsh on September 20, 2007

On Wednesday, September 12, Judge Vermont US District Court Judge William Sessions upheld a Vermont law requiring automakers to cut climate-warming vehicle emissions 30 percent by 2016. Fortunately for autoworkers concerned about losing their jobs, the omniscient judge declared that job losses “would be small (pg 89, ruling).” I bet that was comforting.

 That’s the bad news. The good news is that a federal judge in San Francisco ruled on September 17 that auto companies cannot be held liable for future damages in California caused by global warming.  In a decision atypical of the activism that characterizes our courts today, Judge Martin Jenkins dismissed California’s claims against the automakers because, “policy decisions concerning the authority and standards for carbon dioxide emissions lie with the political branches of government, and not with the courts."

 Given the current composition of Congress, who knows what deferring to the political process on global warming will lead to. Judge Jenkins nonetheless deserves plaudits for having the courage to make such an unpopular ruling.

Misery Loves Company

by Julie Walsh on September 20, 2007

 

Even though the House and Senate anti-energy bills and the various cap-and-trade bills to ration energy are stalled for the moment, the campaign against affordable energy continues in Washington. As reported by Reuters, Rep. Henry Waxman (D-Calif.), Chairman of the House Oversight and Government Reform Committee, has written a letter to the Administrator of the Environmental Protection Agency, Stephen Johnson, claiming that the EPA's recent licensing of construction of a coal-fired power plant in Utah is illegal.

Waxman's letter argues that the Supreme Court's decision in Massachusetts v. EPA defines carbon dioxide as a pollutant and therefore EPA is legally obliged to regulate it. I don't doubt that EPA may eventually decide to regulate CO2 emissions, but Waxman is jumping the gun. EPA is in the process of deciding whether and how to regulate CO2 from autos and trucks, as the Supreme Court ordered it to do. Power plants may indeed be included in that decision. In the meantime, EPA has no regulations in place to regulate carbon dioxide emissions. To deny a permit for a new power plant today on the grounds that greenhouse gases may be regulated in the future would be an audacious as well as most peculiar expansion of regulatory authority.

Waxman is trying to add another weapon to the burgeoning campaign against coal by environmental pressure groups. The fact is that the growing demand for electricity in America cannot possibly be met in the next few years without building scores, perhaps even hundreds, of new coal-fired plants. If Waxman and his allies are successful, the result will be to export California's electricity shortages, blackouts, and high prices to the rest of the country. Misery really does love company.

AN INCONVENIENT TRUTH SPECIAL

With Al Gore\'s movie An Inconvenient Truth hitting cinema screens across Europe, here are links to some critiques of the film:

Gorey Truths: 25 Inconvenient Truths for Al Gore
National Review Online, June 22 2006
[T]his is a good time to point out that the book, which is a largely pictorial representation of the movies graphical presentation, exaggerates the evidence surrounding global warming. Ironically, the former Vice President leaves out many truths that are inconvenient for his argument. Here are just 25 of them.

A Skeptic\'s Guide to An Inconvenient Truth
Competitive Enterprise Institute, August 21 2006
An Inconvenient Truth (AIT), Vice President Al Gores book on The planetary emergency of global warming and what can be done about it, is not the non-partisan, non-ideological exposition of climate science and moral common-sense that it purports to be. Rather, AIT is a colorfully illustrated lawyers brief for global warming alarmism and energy rationing.

In a recent op-ed published in the Washington Post, science historian Naomi Oreskes, elaborating on her essay for Science magazine, argued that the nation’s leaders were ignoring a unanimous agreement in the scientific literature that man is responsible for global warming and that something must therefore be done about it. Yet an examination of the form the much-touted scientific consensus actually takes reveals that it does not mandate policy choices. Moreover, the charge that people are denying what Orsekes defines as the consensus appears to be a straw man. It is therefore worth asking what the point is of this argument, which is growing increasingly popular.  

What do scientists mean when they talk about the “scientific consensus on climate change”? The answer is helpfully provided by the new web log set up by a variety of climate scientists entitled realclimate.org. There, British Antarctic Survey scientist William Connolley defines the consensus in these terms: 

“The main points that most would agree on as ‘the consensus’ are:
1.       The earth is getting warmer (0.6 +/- 0.2 C in the past century; 0.1 C/decade over the last 30 years)
2.       People are causing this
3.       If GHG emissions continue, the warming will continue and indeed accelerate
4.       (This will be a problem and we ought to do something about it)”

 Connolley also includes the following important rider:

“I’ve put those four points in rough order of certainty. The last one is in brackets because whilst many would agree, many others (who agree with 1-3) would not, at least without qualification. It’s probably not a part of the core consensus in the way 1-3 are. Mostof us here on RealClimate are physical scientistswe can talk sensibly about past, present and future changes in climate, but potential impacts on ecosystems or human society are out of our field.”

 This is a useful summary, because it enables us to see where the disagreements lie. Point 1 is generally accepted, although the fact remains that satellite temperature measurements show a smaller warming trend and the reasons for that remain a topic of genuine scientific debate. Nevertheless, there is general agreement that the world warmed slightly over the past century.

 Point 2 is rather imprecisely worded as everyone agrees that temperature changes over the last century have been affected by a variety of human and natural effects, both warming and cooling. The idea that man has not affected the climate in any way has virtually no supporters. Roger Pielke, Jr.no skepticof the University of Colorado compiled a list where he demonstrates that all the so-called skeptics, including Fred Singer, Pat Michaels and even President Bush, have accepted that there is an anthropogenic influence on climate. The claim that opinion-formers deny this is a classic straw man.

 Yet all scientists agree that there is more than just one form of human influence. As well as greenhouse gases, land-use changes, aerosol concentrations and other “forcings” have a role to play. At the time of the last IPCC report, we knew a lot only about the role of greenhouse gases (see figure 9 here), but we have invested a lot of time, money and energy into finding out more about the other forcings. They have enabled scientists to declare that such factors as land-use changes and black carbon (soot) concentrations may account for large portions of the recent warming. Moreover, we now know more about natural forcings such as the oceanic phenomenon known as the Pacific Decadal Oscillation which some researchers think may account for half of the recent warming trend. This is an area of genuine ongoing scientific discovery.

 Point 3 is more contentious, as it relies on theories that assume that there is a so-called “positive feedback mechanism” in the atmosphere that will accelerate any warming trend. This is where the so-called skeptical scientists part company with the consensus. MIT Professor of Meteorology Richard Lindzen, for instance, is well-known for having advanced a credible, peer-reviewed theory that the Earth has an infrared “iris effect” that will produce negative feedbacks. Recent NASA research indicates that feedback mechanisms are not as pronounced as climate models suggest. This is again an area of ongoing scientific discovery, yet the genuine disagreement here would not have shown up as dissent in Oreskes’ research as she actually defines the consensus as “that Earth’s climate is heating up and human activities are part of the reason” — in other words, she defines the consensus as points 1 and 2 of Connolley’s definition, which, as we have seen, are not really in question.

 Yet the reason for Orsekes’ principal complaintthat we are not doing anything about global warmingcan only stem from point 4, which as Connolley says does not really form part of the core consensus and in fact lies in many aspects outside the realm of science. Indeed, one of the commentators on Connolley’s post points out that there may well be a fifth, economic component to the consensus, “that global warming may be badbut it is NOT as bad as what it would take to prevent it.” Connolley accepted this as perfectly valid, and it is backed by economic analysis exercises such as the Copenhagen Consensus which found currently proposed mitigation measures like Kyoto to be poor investments of the world’s resources.

Orsekes has therefore cheerfully elided a genuine consensus on points 1 and 2 of Connolly’s definition into an assertion that this mandates policy action. It can do no such thing. Science only alerts us to possible problems and potential solutions; it is the job of economics, within the political process, to determine whether action should be taken and if so, which of the potential solutions science has identified should be chosen (and even then, we may choose not to adopt the whole solution).

 So if Oreskes’ work is based on a false premise, as it seems to be, does it have any other worth? It may be said that it is useful that she has demonstrated a consensus exists. This is made problematic by the fact that Orsekes has since admitted that she looked at only about 1,000 scientific abstracts out of 11,000 relevant articles (and the question of whether analyzing abstracts gives a true reflection of the nuances of the full article remains open).

Yet even if we take her result at face value, it is really only to be expected. We have known since Thomas Kuhn’s masterpiece, The Structure of Scientific Revolutions, that at any one time in any science there exists a consensusthe paradigm, as Kuhn termed it. That one should exist even in a relatively new discipline such as climatology is unsurprising. In the end, Oreskes is presenting a truism as evidence against a straw man. That’s no way for scientific debate to advance.

In a case of the bugbear of the 1980s meeting the hobgoblin of the 1990s, scientists have found that acid rain can slow global warming by reducing methane emissions from natural wetland areas.

The new study, led by Vincent Gauci of Britains Open University together with colleagues at NASA and published in Proceedings of the National Academy of Sciences, finds that acid rain counteracts the natural production of methane gases by microbes in wetland areas.

As New Scientist says (Aug. 3), “Methane is thought to account for 22 percent of the human-enhanced greenhouse effect. And microbes in wetland areas are its biggest producers. They feed off substrates such as hydrogen and acetate in peat and emit methane into the atmosphere.”

The theory is that global warming itself will speed up the production of methane, “as heating up the microbes causes them to produce even more methane. But the new model suggests that sulphur [sic] pollution from industry cancels this out. This is because sulphur-eating bacteria also found in wetland regions outcompete the methane-emitting microbes for substrates. Experiments have shown that sulphur deposits can reduce methane production in small regions by up to 30 per cent by activating sulphur-eating bacteria.”

Atmospheric concentrations of methane have leveled off in the past few years.

The Edison Electric Institute (EEI), the association of shareholder-owned electric power companies, opposes the Kyoto Protocol, the McCain-Lieberman Climate Stewardship Act, and kindred proposals to regulate carbon dioxide (CO2), the inescapable byproduct of the carbon-based fuelscoal, oil, and natural gasthat supply 86 percent of all the energy Americans use. Why, then, is EEI pressing the Bush Administration to institute an early credit programthe accounting framework and political setup for Kyoto-style energy rationing? Edison has a lot of explaining to do.

Liebermans Ploy

Although the implementing rules of an early credit program can be bewilderingly complex, the basic idea is simple. Under such programs, companies that take steps now to reduce emissions of greenhouse gaseschiefly CO2 from fossil energy useearn credits (emission allowances) they can use later to comply with Kyoto or a similar compulsory regime.

 All such schemes are Trojan horses for Kyoto-type policies. Credits awarded for early reductions are assets that mature and attain full market value only under a mandatory emissions reduction target or cap. Consequently, every credit holder acquires an incentive to lobby for emission caps.

 Unsurprisingly, credit for early reductions originated as a brainchild of the Green Left. Senator Joseph Lieberman (D-Conn.), Environmental Defense, and the Pew Center on Global Climate Change championed early credit legislation during the 105th and 106th Congresses. Liebermans bill went nowhere, attracting only 12 co-sponsors on its second go-round. Similarly, a House companion bill in the 106th Congress garnered a mere 15 co-sponsors. Neither bill saw floor action or even made it to the committee markup stage. By mid-2000, credit for early reductions was politically defunct.

 So why is this an issue today? On Valentines Day 2002, the Bush Administration naively resuscitated Liebermans ploy. President Bush directed the Department of Energy (DOE) to enhance the measurement accuracy, reliability, and verifiability of the Voluntary Reporting of Greenhouse Gases Program (VRGGP), established under Section 1605(b) of the 1992 Energy Policy Act. More importantly, Bush tasked DOE to develop recommendations to give transferable credits to companies that can show real emissions reductions under a revised, more rigorous reporting system.

 To carry out those directives, DOE in May 2002 launched an extensive stakeholder dialogue, which has included three public comment periods, four regional workshops in November-December 2002, and a national workshop in Washington, D.C. on January 12, 2004. A fourth comment period is planned for this summer, and DOE may host another workshop as well.

 Legally Challenged

Scores of industry representatives have spent literally thousands of hours helping DOE enhance the VRGGP, and will likely spend thousands more before the years end. Alas, Bush officials not only endorsed early credits without thinking through the political ramifications, they also never bothered to check whether current law allows DOE to set up a credit program in the first place.

 This was not a difficult topic to research. Section 1605(b) is only one and a half pages long. It makes no reference, or even allusion, to tradable credits. Similarly, the Conference Reports discussion of 1605(b) does not say or imply anything about credits. Equally telling, when House and Senate conferees produced the final version of 1605(b), they considered and rejected language that would have established a credit program.

 During the first (May 6-June 5, 2002) comment period, several stakeholders who support early credits in principlethe Pew Center on Global Climate Change, the Northeast States for Coordinated Air Use Management, and a coalition of environmental groups led by the Natural Resources Defense Councilcautioned DOE that it lacks statutory authority to implement a credit program. During the second (September 2002-October 2003) comment period, the Competitive Enterprise Institute debated the issue at length with the Electric Power Industry Climate Initiative, an association of which EEI is a member. In all that time, DOE declined to explain its understanding of the law.

 On November 26, 2003, DOE released its proposed revised general guidelines to make voluntary emissions reporting more rigorous, consistent, and auditable. Startlingly, the guidelines said not a word about credits, even though whole point of the exercise was to build the accounting system for a credit program. Pressed for an explanation at the D.C. stakeholder workshop this past January, a DOE official  s sss stated, sheepishly and without elaboration: DOE has determined it doesnt have explicit authority now to issue transferable credits.

 An EEI representative at the workshop chided DOE for waiting so long to address this matter and never requesting the legal authority it now believes it lacks. Behind the scenes, EEI has been advising the White House to move ahead with a credit program notwithstanding DOEs legal qualms.

Case Against Credits

Several free market organizationsthe Competitive Enterprise Institute, American Conservative Union, Americans for Tax Reform, American Legislative Exchange Council, Citizens Against Government Waste, Citizens for a Sound Economy, Consumer Alert, Frontiers of Freedom, National Taxpayers Union, Small Business Survival Committee, and 60-Plus Associationhave repeatedly warned the Administration about the political and economic perils of early credit programs. Not once has any Bush official attempted to rebut their arguments. 

However, EEI and its member companies spend millions of dollars on campaign contributions, and in politics, money talks.[1] Unless conservatives on Capitol Hill quickly weigh in, Lieberman, Pew, and Environmental Defense may achieve under Bush-Cheney what they could not under Clinton-Gore. In their conversations with DOE and White House officials, the friends of affordable energy in Congress should stress the following points:

(1) Transferable Credits Will Mobilize Pro-Kyoto Lobbying.

Transferable credit programs are inherently mischievous. Credits awarded for early reductions become valuable assets only under a legally binding emissions cap. That is because, although many companies would like to sell carbon creditsespecially if they can earn the credits by reducing or, easier still, avoiding emissions they would reduce or avoid anyway, in the normal course of business operationsno company will buy credits unless faced with a cap or the threat of a cap. Without buyers, there are no sellers and, hence, no market.

 Consider the embarrassingly low opening bids at the Chicago Climate Exchange (CCE). The Greenwire news service reported that, at the first auction, the exchanges 22 member companies and municipalities paid an average of less than $1 for the right to emit one ton of CO2.[2]  Why? Former CCE senior vice president for sales and marketing Ethan Hodel explained: Without regulation and governmentally imposed sanctions, the early evidence is that the American business community is not very interested in a voluntary greenhouse gas cap-and-trade program. Were it not for the risk that Congress may cap carbon emissions in the future, the bid price for credits today would be zero.

 Enacting a cap would instantly pump up demand, boosting credit prices by orders of magnitude. For example, according to the Energy Information Administration (EIA), carbon equivalent credits that sell for next to nothing today would fetch $93-$122 per ton under Sen. James Jeffordss (I-Vt.) Clean Power Act, $79-$223 per ton under McCain-Lieberman, and $67-$348 per ton under Kyoto.[3]  Clearly, credit holders must lobby for regulation and governmentally imposed sanctions if they want to turn voluntary reductions into real money.

(2) A Credit Program Will Coerce Companies to Volunteer.

 Proponents are fond of describing credits as voluntary and win-win (good for business, good for the environment). In reality, transferable credits would set up a coercive zero-sum game in which one companys gain is anothers loss.

 A explained above, credits have no value apart from an actual or anticipated emissions capa legal limit on the quantity of emissions a firm, sector, or nation may release. The cap makes credits valuable by creating an artificial scarcity in the right to produce or use carbon-based energy. Both the market value of the credits and the programs environmental integrity absolutely depend on enforcement of the cap.

 And theres the rub. If the cap is not to be broken, then the quantity of credits allocated to companies in the mandatory period must be reduced by the exact number awarded for early reductions in the voluntary period. Thus, for every company that earns a credit for early action, there must be another that loses a credit under the cap. Companies that do not volunteer will be penalizedforced in the mandatory period to make deeper emission cuts than the cap itself would require, or pay higher credit prices than would otherwise prevail.

 The coercive, zero-sum nature of an early credit program is easily illustrated. Assume for simplicitys sake that there are only four companies in the United States (A, B, C, and D), each emitting 25 metric tons (MT) of CO2, for a national total of 100 MT. Also assume that Congress enacts a mandatory emissions reduction target of 80 MT, and authorizes the Environmental Protection Agency to issue 80 tradable allowances or credits (1 credit being an authorization to emit 1 MT). Absent an early credit program, each company would receive 20 allowances during the compliance period, and have to reduce its emissions by 5 MT.

 Now assume there is an early action program that sets aside 20 allowances for reductions achieved before the compliance period. That reduces each companys compliance period allocation from 20 credits to 15 (4 companies X 15 credits each = 60 + 20 early action credits = 80, the total U.S. emissions budget). Finally, assume that Companies A and B each earns 10 credits for early reductions. In the compliance period, A and B will have 25 credits apiece (10 + 15), which is 5 more (25 instead of 20) than an equal share under the cap would give them. In contrast, C and D will each have 5 fewer credits (15 instead of 20). C and D must make deeper reductions than the cap would otherwise requireor they must purchase additional credits from A and B. Either way, the early reducers gain at the expense of non-participants.

 Programs that penalize non-participants are coercive, not voluntary. Programs that enrich participants at the expense of non-participants are zero-sum, not win-win.

 (3) Credits Will Corrupt the Politics of Energy Policy.

 Once companies figure out that the program will transfer wealthin the form of tradable emission allowancesfrom those who do not act early to those who do, many will volunteer just to avoid getting stuck in the shallow end of the credit pool later on. The predictable outcome is a surge in the number of companies holding conditional energy rationing couponsassets worth little or nothing under current law but worth millions or billions of dollars under Kyoto, McCain-Lieberman, or the Clean Power Act. Credits will swell the ranks of companies lobbying for anti-consumer, anti-energy policies.

 (4) Credits Will Limit Fuel Diversity.

 Coal is the most carbon-intensive fuel (CO2 emissions per unit of energy obtained from coal are nearly 80 percent higher than those from natural gas and about 35 percent higher than those from gasoline).[4] Consequently, Kyoto-type policies can easily decimate coal as a fuel source for electric power generation. For example, according to EIAs analysis, the McCain-Lieberman bill would reduce U.S. coal-fired electric generation in 2025 by 80 percentfrom 2,803 billion kilowatt hours to 560 billion kilowatt hours.[5]

 A transferable credit program will send a political signal that mandatory reductions are in the offing and, hence, that coals days are numbered. As environmental lawyer William Pedersen observes, the Administrations plan to develop company-by-company greenhouse emissions accounts makes little sense except as a step towards legally binding controls. Indeed, why would firms go to the trouble and expense of earning offsets applicable to a future regulatory program unless they believed such a program was coming?[6] DOE cannot issue or certify early credits without ratifying the opinion, tirelessly asserted by green groups, that some form of carbon regulation is inevitable. Anticipating such constraints, many companies will make plans to switch from coal to natural gas. That, in turn, will put additional pressure on already tight natural gas supplies.

 According to a recent study by the Industrial Energy Consumers of America, the 46-month natural gas supply crunch has increased average natural gas prices by 86 percent, costing residential and industrial consumers $130 billion. High gas prices have also contributed to job and export losses, because many manufacturing firms use natural gas both as a feedstock and as fuel to power their plants.[7]

 However unfairly, Democratic candidates blame Bush and the GOP for the loss of 2.8 million manufacturing jobs since January 2001. Politically speaking, the last thing the Administration can afford to do is imperil additional manufacturing jobs by driving up further the demand for and cost of natural gas. An early credit program would have exactly those effects.

 (5) Credits Have No Redeeming Environmental Value.

 A study in the November 1, 2002 issue of the journal Science examined possible technology options that might be used in coming decades to stabilize atmospheric CO2 concentrations.[8] Such options include wind and solar energy, nuclear fission and fusion, biomass fuels, efficiency improvements, carbon sequestration, and hydrogen fuel cells. The report found that, All these approaches currently have severe deficiencies that limit their ability to stabilize global climate. It specifically disagreed with the U.N. Intergovernmental Panel on Climate Changes claim that, known technological options could achieve a broad range of atmospheric CO2 stabilization levels, such as 550 ppm, 450 ppm or below over the next 100 years.

 As the study noted, world energy demand could triple by 2050. Yet, Energy sources that can produce 100 to 300 percent of present world power consumption without greenhouse emissions do not exist operationally or as pilot plants. The bottom line: CO2 is a combustion product vital to how civilization is powered; it cannot be regulated away.

 Given current and foreseeable technological capabilities, any serious attempt to stabilize CO2 levels via regulation would be economically devastating and, thus, politically unsustainable.

 Why is this relevant to the debate on early credits? No good purpose is served by creating the pre-regulatory ramp-up to unsustainable regulation. An early start on a journey one cannot complete and should not take is not progress; it is wasted effort.

 Insuring Disaster

 The rejoinder to the foregoing criticisms is that companies participating in the Administrations voluntary climate programs need credits as an insurance policy, hedging strategy, or baseline protection mechanism so that they will not have to do double duty (reduce emissions from already lowered baselines) under a future climate policy.

 However, an insurance policy that makes the insured-against event much likelier to happen is a prescription for disaster. Kyoto insurance in the form of early credits would do exactly that. To repeat, credits worth little or nothing under current law would be worth big bucks under a carbon cap-and-trade program. Early credit holders stand to gain windfall profits if they successfully lobby for mandatory reductions. A Kyoto hedge fund dramatically increases the odds that Congress will enact Kyoto-like policies.

 Not all hedging strategies deserve approbation and support. A prizefighter caught placing bets on his opponent might sayand possibly even believethat he was just hedging. However, most people would conclude the fix was in. That early credits are part and parcel of a Kyoto fix for U.S. energy markets may be inferred not only from the cap-and-trade clientele such a program would build, but also from the fact that Kyoto insurance salesmen work both sides of the street.

 Many leading proponents of early creditsSen. Lieberman, Environmental Defense, the Pew Center on Global Climate Change, Resources for the Future, Dupont Co., British Petroleum, and the Clean Energy Groupare also among the leading proponents of emissions cap-and-trade programs. They are in the odd position of advocating a hedge against, or demanding baseline protection from, the very policies they promote!

 The U.S. Senate would never ratify Kyoto, nor would Congress ever enact McCain-Lieberman or the Clean Power Act, unless pushed to do so by many of the same policymakers, companies, and activist groups advocating credit for early reductions. If they really wanted to, Sen. Lieberman, Pew, Dupont, et al. could easily ensure that good corporate citizens are not penalized in the future for voluntary reductions today. All they would need to do is disavow their support for cap-and-trade!

 Instead, those worthies try to sell protection from a threat they have in large measure created. Moreover, they do so knowing full well that Kyoto insurance would (a) make the threat of carbon suppression more imminent and certain, and (b) penalize firms whose only offense is not complying in advance with emission control requirements that Congress has not yet enacted.

Economy in the balance

 The carbon in coal, oil, and natural gas is not an impurity or contaminant but an intrinsic component of their chemistry as fuels. That is why carbon dioxide is an unavoidable combustion byproduct of those fuels, why capping CO2 emissions is a form of energy rationing, and why there is no logical stopping point short of total suppression once government starts to regulate energy production based on the carbon content of emissions or fuels. 

 The core issue underlying all climate policy debates is whether politicians and bureaucrats should have the power to regulate America into a condition of energy poverty. The Edison Electric Institute surely believes government should not have such power, which is why it opposes Kyoto and other carbon cap-and-trade schemes. Yet EEI, beguiled by the prospect of turning voluntary reductions into easy cash, is leading the charge for transferable creditsa political force multiplier for the Kyoto agenda of climate alarmism and energy suppression. This is about as sensible as selling the rope by which one will be hanged. The nations premier electric industry lobby can and should do better.

Nature Ignores Science on Greenland Ice Shelf

A feature article, Rising Tide, in the March 11 issue of Nature claims that global warming is melting Greenlands ice so rapidly that the whole ice sheet may melt and cause sea levels to rise significantly. However, as the Greening Earth Societys World Climate Alert (http://www.co2andclimate.org/wca/2004/wca_14d.html) points out, the Nature article is at variance with published scientific research, which finds that Greenland warmed rapidly in the 1920s without causing disastrous melting of the ice sheet, but has been in a cooling trend since 1940. 

The most recent of a number of research articles that contradict Nature is Global Warming and the Greenland Ice Sheet, by P. Chylek, J. E. Box, and G. Lesins, which appears in the March issue of Climate Change.  The articles abstract says, Since 1940, however, the Greenland coastal stations data have undergone predominantly a cooling trend.   At the summit of the Greenland ice sheet, the summer average temperature has decreased at the rate of 2.2C per decade since the beginning of the measurements in 1987.  This suggests that the Greenland ice sheet and coastal regions are not following the current global warming trend.

The authors found the most pronounced warming in the 1920s when the average annual surface air temperature rose between 2C and 4C in less than 10 yearsat a time when the change in anthropogenic production of greenhouse gases was well below the current level.

World Climate Alert points out, A 1C warming of the coastal stations would cause an increase in the melt area of 73,000 square kilometers, as Chylek et al. note.  Given the 1C to nearly 2C cooling found in the coastal stations, Chyleks team makes this conservative statement, The results are inconclusive for the ice sheet as a whole, owing to the large uncertainties when balancing very large, difficult to measure, offsetting quantities.  They add, Even the direction in which the mass of the Greenland ice sheet is currently changing is in dispute.  In other words, anyone who claims Greenland is melting wont find a lot of support in the scientific literature.

NASA Finds Global Climate Models Overestimate Warming

A NASA press release dated March 16 contains interesting news for those who have disputed the strength of positive water vapor feedback effects in global climate models.

The release states, A NASA-funded study found some climate models might be overestimating the amount of water vapor entering the atmosphere as the Earth warms.  Since water vapor is the most important heat-trapping greenhouse gas in our atmosphere, some climate forecasts may be overestimating future temperature increases.

Ken Minschwaner, a physicist at the New Mexico Institute of Mining and Technology, Socorro, N.M., and Andrew Dessler, a researcher with the University of Maryland, College Park, and NASA’s Goddard Space Flight Center, Greenbelt, Md., did the study.  It is in the March 15 issue of the American Meteorological Society’s Journal of Climate.  The researchers used data on water vapor in the upper troposphere (10-14 km or 6-9 miles altitude) from NASA’s Upper Atmosphere Research Satellite (UARS).

Their work verified water vapor is increasing in the atmosphere as the surface warms.  They found the increases in water vapor were not as high as many climate-forecasting computer models have assumed.  Our study confirms the existence of a positive water vapor feedback in the atmosphere, but it may be weaker than we expected, Minschwaner said.

In most computer models relative humidity tends to remain fixed at current levels.  Models that include water vapor feedback with constant relative humidity predict the Earth’s surface will warm nearly twice as much over the next 100 years as models that contain no water vapor feedback.

Using the UARS data to actually quantify both specific humidity and relative humidity, the researchers found, while water vapor does increase with temperature in the upper troposphere, the feedback effect is not as strong as models have predicted. The increases in water vapor with warmer temperatures are not large enough to maintain a constant relative humidity, Minschwaner said. These new findings will be useful for testing and improving global climate models.

Scientists Play Historians

Stepping up the attack on the study by Willie Soon et al. that demonstrates that there is nothing unusual about temperatures in this century, Michael Mann’s coauthor Philip Jones of the University of East Anglia played amateur historian when he tried to explain away common knowledge about past warm and cold spells in Northern Europe. He pointed the Guardian (Sept. 1) towards the part of their paper (see last issue) that contends that many of the obvious indicators of past temperature variability do not mean what people suppose they mean.

Mann et al. contend that the medieval presence of vineyards in Britain is meaningless because there are 350 vineyards there now, compared to 50 or 60 in the Middle Ages. In arguing thus, they ignore advances in technology that allow vineyards to prosper in colder climates as well as increases in population (there were 5-6 million people in England before the Black Death, making the rate of vineyards to people almost twice as high as it is today).

They also allege that the Viking colonization of Greenland was motivated by exile, not by a search for good climate. This may be true, but has no bearing on the fact that evidence from insect habitats shows that Greenland was livable at that time but ceased to be afterwards. The Viking settlers were forced to abandon Greenland when they were no longer able to grow hay to feed their livestock.

Finally, the researchers allege that the Little Ice Age-era “frost fairs” on the River Thames in London were possible only because the design of London Bridge dammed the tidal flow of salt water upstream. This appears to ignore the fact that that particular design of London Bridge was first built in 1176, while frost fairs did not begin till much later. Whatever the effects of the bridge, temperatures much colder than today would still have been necessary for the river to freeze.

A wealth of information on the Little Ice Age as a global phenomenon may be found in University of California archaeologist Brian Fagan’s book, The Little Ice Age, published by Basic Books in 2000. The chapters on “The Great Hunger” and “The Specter of Hunger” are especially instructive. Apparently, Mann and Jones have not had time to read it.

Satellite Wars

The attempts to discredit John Christy and Roy Spencer’s satellite data that show no appreciable warming in the atmosphere over recent years continue. Ben Santer and his colleagues, who prefer the recalibration of the data from Remote Sensing Systems because it fits their climate model better, argue in a letter to Science (Aug. 22) in response to Christy’s criticisms of their data that the independent validation of Christy’s data by weather balloon measurements are “not an unambiguous ‘gold standard’ for the evaluation of satellite data.”

The Greening Earth Society comments (www.co2andclimate.org/co2report/int_0902.html), “Different agencies and researchers have put together several different compilations of the weather-balloon data records. Each has been carefully scrutinized and corrected to the best ability of the respective researchers in order to account for the data problems Santer describes. The methods used to make these corrections vary across research groups. Yet, when the final data are combined and global trends examined, the trends fall very close to (and in most cases are slightly less than) the UAH satellite record.

“Santer and his co-authors would be in a much stronger position if the global trends from weather-balloon data were all over the board, with some closer to the RSS trend than to the UAH trend. But that isn’t the case. The consistency of results indicates that the weather-balloon record errors Santer is so worried about are not nearly as problematic as they lead the reader to believe they are. This is because the errors are accounted for. As a consequence, any claim that climate models are better than actual observations rings hollow.

“There remains a large discrepancy between the patterns of temperature change at the surface and those in the lower to middle atmosphere (especially in the tropics) that the model does not replicate. This discrepancy indicates a fundamental weakness in the current generation of climate models. Something in their internal workings fails to parameterize negative feedback loops that appear to be ridding the atmosphere of excess greenhouse heating. As a result they overestimate future warming rates. The controversy continues.”
