AI Study Reveals Effective Climate Policies

- Researchers used machine learning to analyze 1,500 climate policies, identifying 63 that significantly reduced emissions.
- These policies, implemented in 35 countries, cut emissions by 19% on average, totaling between 0.6 and 1.8 gigatonnes of CO2 equivalent.
- Effective policies often combined multiple tools, such as the UK's coal phase-out with carbon pricing and Norway's electric car incentives.
- The study highlights the importance of the right policy mix over the sheer number of policies.
- The findings serve as a warning that current global climate policies need re-evaluation to meet future emission targets.
