Evaluation of climate policy measures over two decades finds many have failed to achieve necessary emissions reductions

Combining climate measures key to slashing emissions: study

A major new study published Thursday on the effectiveness of climate measures such as taxes or subsidies in reducing greenhouse gases has found stand-alone measures fail to make a big difference. Published in the journal Science, the study examined 25 years of public policies in 41 countries across six continents. It concluded that out of the 1,500 policies analysed in sectors including energy, transport and construction, “only 63 cases of succe…

AI analysed 1,500 policies to cut emissions. These ones worked

Only 63 climate change interventions led to significant reductions in carbon emissions. Only 63 climate change interventions led to significant reductions in carbon emissions.

Mix of climate policies more effective for emissions reductions

Analysis of 1,500 global climate policies has revealed new insights into the policy combinations that are effective in reducing emissions. The new research finds only 63 policy interventions successfully reduced total emissions between 0.6 billion and 1.8 billion tons of CO2. Effective national climate policies are crucial to achieve the Paris Agreement’s goal to limit average global warming to well below 2 °C above pre-industrial levels and to …

World's most effective climate policies identified in new study

Countries around the world have implemented carbon pricing, electric vehicle incentives and more than 1,000 other policies in an effort to cut carbon emissions and slow climate change. But which ones actually work? A new global study has identified 63 of the most effective, and found some patterns.
