John F. Kerry

John F. Kerry  stepped down in March as President Joe Biden’s special presidential envoy for climate. He was a driving force for American climate policy, led the US negotiating team through three United Nations climate summits, and played a crucial role in urging President Biden to set a more aggressive target for greenhouse gas emissions. He was granted a seat on the National Security Council in the White House, marking the first time an official on that body was dedicated specifically to climate change.
