Gina McCarthy will leave her post as top domestic climate adviser to President Joe Biden on 16 September amid intensifying moves by cabinet departments to ramp-up action to spur the US transition to cleaner energy.

Ali Zaidi, her deputy, will take over as National Climate Advisor from the influential McCarthy, whose office helped draft provisions of a new climate law that includes $369bn in related spending and clean energy-related tax credits, the biggest such investment in US history.

Separately, John Podesta, longtime aide and political operative for President Bill Clinton and former Secretary of State Hillary Clinton, will join the White House in a newly created post as senior advisor to Biden for clean energy innovation and implementation.
