What Works: Groundbreaking Evaluation of Climate Policy Measures over Two Decades

“More policies do not necessarily equate to better outcomes. Instead, the right mix of measures is crucial. For example, subsidies or regulations alone are insufficient; only in combination with price-based instruments, such as carbon and energy taxes, can they deliver substantial emission reductions.” revealed Nicolas Koch from the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC). In collaboration with experts from the University of Oxford, the University of Victoria, and the OECD, researchers at PIK and MCC conducted a study to assess the impact of 1500 policy interventions implemented between 1998 and 2022.

This research aims to provide new insights into climate change policies by analyzing a wide range of policy instruments and tailoring measures for both industrialized and developed countries. By using machine learning methods and the largest OECD database, the researchers identified policy interventions that can enable significant emission reductions. More specific data can be found in the interactive Climate Policy Explorer.
