Democratic presidential candidate Sen. Elizabeth Warren (D-Mass.) on Monday unveiled a vision to put Americas public lands to work in the fight against climate change, vowing to ban new fossil fuel leases and dramatically boost renewable energy on federal lands and waters.

The proposal is a rebuke of President Donald Trump , whose record on public lands includes offering up millions of federal acres for oil and gas leasing, some for as little as $1.50 per acre, proposing to open nearly all U.S. waters to offshore drilling, and leading the largest rollback of national monuments in U.S. history .

The Trump Administration is busy selling off our public lands to the oil, gas and coal industries for pennies on the dollar, threatening the health and safety of our local communities and pouring an accelerant on our climate crisis, Warren said in an email statement. We cant allow corporations to pillage our public lands and leave taxpayers to clean up the mess.

If elected, the Massachusetts senator promised to issue an immediate executive order imposing a moratorium on new oil, gas and coal leases, both on federal land and offshore. The policy would set a goal of generating 10% of the nations power from renewables on public land, a nearly tenfold increase from today.

Warren, who has a 99% lifetime score from environmental group League of Conservation Voters, appears to be the first presidential contender to outline a detailed public lands policy. The proposal comes ahead of a three-state campaign tour this week that includes stops in South Carolina, Colorado and Utah, where Warren is likely to push the initiative.

Its not enough to end our public lands contribution to climate change, Warren wrote in an announcement on Medium . We have an enormous opportunity to make them a part of the climate solution, and for both economic and environmental reasons, we should take it.
