‘All in’ climate diplomacy: How a Biden-Harris administration can leverage city, state, business, and community climate action

As the U.S. federal government reengages with international climate policy, it should not retire the groundswell of city, state, business, and community climate action that has held the line for the last four years, but incorporate it into a reinvigorated “all in” climate diplomacy. Specifically, the Biden-Harris administration should:

Leverage climate action across all of society to ensure that U.S. climate targets represent maximum ambition while highlighting credible pathways to implementation
Integrate U.S. subnational and nonstate climate action into diplomacy, moving from simply highlighting the scale of non-federal action to actively incorporating it into operational strategies
Create institutional structures in the State Department and the federal organizing architecture, which may include a new National Climate Council, to empower U.S. cities, states, businesses, and communities to drive climate action not just at home but also globally
