Carbon pricing works, major meta-study finds

Reduction of emissions by 5 to 21 %: this is the empirically measured effect of carbon pricing schemes in the first years of their operation. The research team now identifies these findings for 17 real-world climate policies, making the state of knowledge more comprehensive than ever before. The team uses artificial intelligence to compare existing surveys, making them comparable using a new concept of calculation.
