President Joe Biden on Wednesday signed a series of executive orders that prioritize climate change across all levels of government and put the U.S. on track to curb planet-warming carbon emissions.

Biden’s orders direct the secretary of the Interior Department to halt new oil and natural gas leases on public lands and waters, and begin a thorough review of existing permits for fossil fuel development.

The series of actions kick off the president’s agenda to reduce the country’s emissions and establish stricter targets under the Paris climate accord.
