The Climate Change Performance Index (CCPI) 2025 evaluates 63 countries and the European Union, representing 90% of global emissions, across emissions, renewables, and climate policy. While renewable energy shares have increased in 61 of the 64 assessed entities over the last five years, the report finds that many high-emitting nations continue to rely on fossil fuels, leaving the top three overall ranks vacant.

The Climate Change Performance Index (CCPI) 2021 evaluates 57 of the world's highest greenhouse gas emitters, finding that no single country is currently on a path compliant with the Paris Agreement goals. While the European Union improved its ranking to 16th place, the report highlights a stark divide between leading nations and G20 members like the USA, Saudi Arabia, and Russia, who are rated 'very low'.

The Climate Change Performance Index (CCPI) 2017: G20 Edition evaluates the climate efforts of the 20 largest economies, which collectively account for 75% of global greenhouse gas emissions. The index assesses countries based on emissions, energy use, renewable energy, and climate policy to determine if they are on track to meet the Paris Agreement's goal of limiting global warming to well below 2°C.
