The Climate Change Performance Index monitors climate mitigation progress of 63 countries and the European Union, together responsible for more than 90% of global emissions. In recent years, governments around the world have increasingly placed climate action on their agenda, and renewable energy is booming in many countries. However, this still is not enough. The race against time continues: global emissions must nearly halve by 2030, and reducing the use of fossil fuels should account for most of that. As in previous years, not a single assessed country has acted in line with the 1.5-degree limit. Nevertheless, there are big differences in ambition: Denmark is at the top of the index again (4th), followed by the climbers Estonia and Philippines (5th and 6th). Unfortunately, not everyone follows this good example: China, the largest emitter, remains in 51st place, while the US has even dropped five places since last year (now 57th). The host of COP28, the United Arab Emirates (UAE), Iran, and Saudi Arabia form the bottom trio (ranked 65th to 67th).
