State commitments are key. On the occasion of “Earth Day”, the American president organised a virtual climate summit on 22 and 23 April with the main international leaders, including Xi Jinping, Narendra Modi, Angela Merkel, Vladimir Putin and Emmanuel Macron. «This is the decisive decade », he said in his introductory speech.
After joining the Paris Agreement on his first day in office, President Joe Biden pledged at the summit to reduce US greenhouse gas emissions by 50% by 2030, compared to 2005, compared to 26% by 2025 under Obama.
