The former secretary of state, who has been climate envoy since 2021, announced that he is resigning from his position to campaign for Joe Biden.
US climate envoy John Kerry, who plays a key role in the US government's fight against climate change, will resign to contribute to President Biden's re-election campaign, media reported on Saturday.
According to the New York Times, 80-year-old John Kerry's resignation will take effect in the spring.
Since 2021, the former foreign minister and senator has been working with other countries to make commitments on climate change, including at the recent UN climate summit COP28 held in Dubai.
According to several American media outlets, citing officials familiar with the matter, John Kerry intends to participate in Joe Biden's campaign by publicizing the president's work in the fight against global warming.
John Kerry informed Joe Biden of his intention to leave the country on Wednesday, and his team learned of his decision on Saturday, this media reported.
The former secretary of state led the US delegation to three UN climate summits, but also worked effectively with China despite complicated diplomatic relations.
These two countries alone are responsible for around 40% of global greenhouse gas emissions.
In a rare show of unity, the United States and China reached a historic, albeit watered-down, agreement at the COP28 climate summit in December to begin transitioning away from oil, gas and coal, the main contributors to the global climate crisis.
John Kerry had welcomed his Chinese counterpart Xie Zhenhua a month earlier in California, where the two countries agreed on the climate change guidelines that served as part of the basis for the Dubai agreement involving nearly 200 countries.
The news of John Kerry's resignation comes a day after the announcement of Xie Zhenhua's resignation.
