Democratic presidential contender Bernie Sanders on Wednesday unveiled a climate-change bill that would crack down on fossil fuel extraction, a move sure to please activists who want party front-runner Hillary Clinton to make the same commitment.
Sanders, a U.S. senator from Vermont, wants to halt new leases for fossil fuel extraction on public lands and for offshore drilling in the Pacific and Gulf of Mexico.
He would prohibit drilling in the Arctic and Atlantic Ocean.
Sanders pushed for the proposal at a rally at the U.S. Capitol on Wednesday, alongside environmental leaders such as Bill McKibben, co-founder of the grassroots climate group 350.org.
Sanders, who calls himself a democratic socialist, has been Clinton's main rival to be the party's nominee for president in the November 2016 elections.
