Top of Biden’s list is rejoining the international Paris climate accord, a federal review of 100+ policies like curbing heat-trapping emissions by creating fuel economy standards for cars and capping oil and gas industry pollution, and the long-term economic impact of regulations around climate change (carbon’s “social cost”). However, not all recent polls show that Americans put Biden’s climate related action as a top concern. One put climate change well behind health care and the pandemic and another showed only 4% of adults saying climate should be Biden’s top priority.
