Sen. Elizabeth Warren said Monday that she would ban all drilling on federal lands and waters on her first day in office.

“On my first day as president, I will sign an executive order that says no more drilling — a total moratorium on all new fossil fuel leases, including for drilling offshore and on public lands,” the Massachusetts Democrat said in post on Medium outlining her public lands agenda.

Warren also said she would reinstate an Obama-era Interior Department rule that the Trump administration has proposed rolling back limiting leaks of methane, a potent greenhouse gas, from oil and gas operations.

The Warren campaign, in the post, noted that nearly a quarter of U.S. greenhouse gas emissions come from energy production on public lands. The Trump administration has massively expanded oil and gas drilling on federal lands, and has proposed opening nearly all federal waters to oil and gas drilling. It has also encouraged offshore wind leases in federal waters.

Warren says she would prioritize wind and solar development, aiming for renewable energy produced on public lands to generate 10% of U.S. electricity.

She also said she would overturn Trump’s controversial shrinking of two national monuments, Bears Ears and Grand Staircase-Escalante, in Utah.

And she vowed to “eliminate” the infrastructure and maintenance backlog in national parks, a goal the Trump administration shares.
