John Kerry, the US Special Presidential Envoy for Climate, has announced he will step down after three years of service. At 80 years old, Kerry disclosed his decision in January, marking the closure of an era in climate diplomacy defined by his vigorous efforts to mobilize global action against climate change. Appointed by President Joe Biden, Kerry’s tenure symbolized the United States’ re-engagement with the international climate agenda, following a period of retrenchment under the previous administration.

Throughout his tenure, Kerry faced criticism but emphasized the critical nature of international collaboration, notably with China. His relationship with China’s climate envoy, Xie Zhenhua, was instrumental in fostering agreements between the two nations, including a joint declaration at Cop26 that aimed at expediting the transition away from fossil fuels.

Although Kerry is relinquishing his role as a climate envoy, he intends to maintain his advocacy for climate action by contributing to Biden’s re-election campaign and participating in future climate summits. His departure comes amid ongoing challenges in meeting global emission reduction targets.

In his final statements, outgoing climate chief Kerry reaffirmed the US’s commitment to combatting the climate crisis amidst an increase in fossil fuel production. He advocated for the acceleration of a transition to renewable energy and the establishment of strict regulations to phase out existing oil and gas infrastructure, which could become stranded assets. Kerry emphasized the necessity of global efforts to meet the 1.5°C target set by international climate agreements.

Kerry also voiced his intentions to continue working on climate finance, highlighting its pivotal role in the clean energy transition. He stressed the pressing need for increased financial support for initiatives aimed at mitigating climate change’s impacts, pointing to the urgency of demonstrating profitable and sustainable investment mechanisms to support this transition.

Through his continued engagement in climate finance and advocacy, Kerry aims to contribute to the global effort to shift towards a more sustainable future, overcoming economic challenges and facilitating cooperation among various stakeholders in the fight against climate change.
