President Biden seized on climate change as a core priority when he took office, saying days after his inauguration, “We’ve already waited too long to deal with this climate crisis, and we can’t wait any longer.”

The new president spent his first year in the White House trying to match his policies to the urgency of his words. His administration has worked aggressively to make that ambitious agenda a reality — even as success has come in fits and starts.

Much of Biden’s work involved restoring dozens of environmental protections unraveled by Donald Trump’s deregulatory frenzy, but it also includes dozens of new climate policies.
