the need for action to limit global temperature rise to 1.5°C.

In a series of UN reports, thousands of scientists and government reviewers agreed that limiting global temperature rise to no more than 1.5°C would help us avoid the worst climate impacts and maintain a livable climate. Yet policies currently in place point to a 3°C temperature rise by the end of the century.
The emissions that cause climate change come from every part of the world and affect everyone, but some countries produce much more than others.The seven biggest emitters alone (China, the United States of America, India, the European Union, Indonesia, the Russian Federation, and Brazil) accounted for about half of all global greenhouse gas emissions in 2020.
Everyone must take climate action, but people and countries creating more of the problem have a greater responsibility to act first.
