Here’s what happens nextBiden has vowed to reenter the U.S. into the Paris Climate Agreement and bring the country to net-zero emissions by 2050, though his climate agenda will face immense constraint if Republicans maintain control of the Senate.Over the last four years, the Trump administration has dismantled more than 70 major environmental regulations, with nearly 30 more in progress.”Regan will take the EPA’s helm at perhaps the most critical moment in the agency’s history, and he has to do much more than just mop up the toxic mess left by Trump,” said Kierán Suckling, executive director of the Center for Biological Diversity.If the GOP does maintain control of the Senate and hinders climate legislation, Biden’s plans will depend on the EPA to implement regulations that reduce emissions from fossil fuel sites and automobiles.Biden’s administration already plans to implement oil and gas drilling restrictions on public lands, block pipelines across the country and roll back a great deal of Trump’s executive orders on energy.
