'Polluter Pays' Policy Could Lower Carbon Emissions

Washington — To find out what really works as countries try to combat climate change, researchers looked at 1,500 ways countries have tried to reduce greenhouse gas emissions. Their answer: Not much works. And success often means someone pays a price, whether at the pump or elsewhere. According to a new study in the journal Science Thursday's (22/8) edition, researchers found only 63 cases since 1998 that showed policies resulting in significant reductions in carbon pollution, Efforts to phase out fossil fuels and gasoline engines, for example, have not been successful on their own. But they would be more successful if combined with some sort of energy tax or surcharge system, the study authors concluded in an in-depth analysis of global emissions, climate policy and law. “The key if you want to reduce emissions is that you have to have a price in policy making,” said study co-author Nicolas Koch, a climate economist at the Potsdam Institute for Climate Impact Research in Germany. “If subsidies and regulations are applied alone or in combination, you will not see significant emission reductions. However, if price instruments are applied such as carbon energy taxes, then substantial emission reductions can be achieved.” A replica …
