Effective Climate Policies: A Mix of Measures Key to Success, Study Finds

A study analyzing 1,500 climate policies from 1998 to 2022 highlights the importance of using a mix of measures to achieve emission reductions. Policies like subsidies and regulations are most effective when combined with price-based instruments. The findings provide valuable insights into best practices for different sectors and countries.

A recent study analyzing 1,500 climate policies enacted between 1998 and 2022 reveals that a higher number of policies doesn't necessarily lead to better emission reductions. Instead, the right mix of measures is crucial.

Published in the journal Science, the study identifies 63 successful cases, often involving seldom-studied policies and policy combinations. Lead author Nicolas Koch of the Potsdam Institute for Climate Impact Research (PIK) highlighted that subsidies or regulations alone are inefficient, but combining them with price-based mechanisms like carbon and energy taxes can deliver significant results.

The research covers a wide range of policies, from energy-related building codes to carbon taxes. It uses a comprehensive OECD database to identify effective measures, providing new insights for policymakers aiming for climate neutrality.
