A group of mostly Democratic senators has introduced a bill that would require the U.S. to phase out carbon emissions by 2050, placing their faith almost entirely in the Environmental Protection Agency (EPA) to carry out the process.

“Today’s legislation I’m offering centers our country on [an] aggressive and I think achievable path to net-zero greenhouse gas emissions no later than later 2050,” Carper said in a call with reporters. “This is the quickest way we can, I think, jump-start governmentwide climate action by encouraging agencies to use the tools that they already have.”

The bill is the first major piece of climate legislation to be introduced in the Senate this year, rolling out alongside similar efforts still developing in the House.

House Democrats have released a more than 600-page discussion draft of their bill, envisioning the same target but with detailed efforts for reducing emissions from utilities, transportation and infrastructure to reduce emissions on an economywide scale.

Carper said his bill would be an easier lift than that of his House colleagues.

“It’s a much more comprehensive bill,” he said of the House version, but his version has a broader backing from environmental and labor groups, as well as the business community.

Carper also defended the choice to rest decarbonization with the EPA, which under the Trump administration has rolled back a number of environmental regulations, including ones on coal-fired power plants that experts say could hasten climate change.

“There are a lot of good people in the EPA,” he said, while noting a number of senate Republicans who have been more active on climate issues.

Though Carper’s bill has the backing of a number of major environmental groups, a small handful have said it is not aggressive enough.

“We need binding emission reduction targets, in line with what climate justice and historical responsibility demand, far sooner than 2050," environmental group Friends of the Earth wrote in a statement. "Unspecified interim targets are ill-suited to our moment of climate emergency and put too much faith in future administrations."
