When do "Greens" pollute?

When the price of pollution falls, they consume more pollution. It looks as if they respond to incentives, just like the rest of us.

According to statistics from the Swedish Transportation Agency, average emissions from new cars in the country decreased from 164 to 151 grams of CO2 per kilometer driven, Swedish drivers used their green cars to cover more territory than ever before. Thanks in part to better fuel economy and the idea that a green vehicle has a slimmer impact on the environment, the overall result is more fuel burned, more emissions spewed.
