John Kerry, the U.S. special envoy on climate, is set to leave the Biden administration in the forthcoming weeks, as announced by his office. Kerry, who has previously served as a senator, secretary of state, and was the Democratic presidential nominee in 2004, has been an integral part of the Biden administration's efforts to combat climate change. Having played a significant role in the negotiation of the 2015 Paris Climate Deal and the recent UAE consensus on fossil fuel transition, Kerry's expertise in the field of climate action has been widely recognized.

His departure from the administration comes after meeting with President Joe Biden to discuss the future of climate progress, and it is reported that he plans to join Biden's re-election campaign, as the "single biggest factor for climate progress." During his time as the special climate envoy, Kerry has worked tirelessly to promote the urgency of addressing the climate crisis, and played a key role in rejoining the U.S. into the Paris Agreement after the Trump administration had withdrawn from it. He has also been a strong advocate for increasing the funding and support for green energy transitions in developing countries.

While Kerry's reputation as a central figure in global climate discussions has earned him acclaim, he does face criticism from those who argue that America's climate policies lack true leadership in the fight against global warming. The Inflation Reduction Act, the largest climate law in U.S. history, has led some to perceive the law as protectionist, potentially harming their own green industries. As Kerry prepares to depart from his role as the U.S. special envoy on climate, the Biden administration will need to find a suitable replacement to carry forward the fight against climate change on the global stage, in the months leading up to the next election.
