研究开发新方法识别浪费性补贴,发现全球最大碳抵消项目CDM中至少52%的碳额度被分配给本就会建的项目,导致全球二氧化碳排放显著增加。

Abstract

We develop and implement a new method for identifying wasted subsidies and use it to provide systematic evidence of the misallocation of carbon offsets in the Clean Development Mechanism—the world's largest carbon offset program. Using newly constructed data on the locations and characteristics of over 1,000 wind farms in India, we estimate that at least 52 percent of approved carbon offsets were allocated to projects that would very likely have been built anyway. We estimate that the sale of these offsets to regulated polluters resulted in substantially higher global carbon dioxide emissions.
