The British Conservative Party seems intent on fulfilling Prime Minister David Cameron’s promise to be the “greenest government ever.” This week, the coalition government announced it would cut emissions 50 percent, averaged over the years 2023-2027, by 2025. The government conceded that the policy would cost British homes about $700 a year, or 1 percent of Britain’s GDP, which is almost certainly a lowball. There is, however, an escape clause: The targets are binding only if the rest of the European Union commits to the same emissions cuts. Even if the EU were to adopt similar targets, it would not be terribly surprising if a future government suspended or rescinded this ultra-expensive “Green Deal,” as recent polling suggests that only a quarter of Britons believe that the risks of climate change are greater than the benefits.
