WASHINGTON, Feb 7 (Reuters) - Democrats on Thursday laid out a "Green New Deal" that would eliminate U.S. greenhouse gas emissions within a decade, an effort to make climate change a central issue in the 2020 presidential race.

The document, unveiled by rising political star Representative Alexandria Ocasio-Cortez and Senator Edward Markey, marks the first formal attempt by lawmakers to define potential legislation to create big government-led investments in clean energy and infrastructure to transition the U.S. economy away from fossil fuels.

The plan, which takes the form of a non-binding congressional resolution, outlines some of the most aggressive climate goals ever put forward by Democratic lawmakers and clashes dramatically with the Trump administration's efforts to advance domestic oil, gas and coal production by rolling back environmental protections.

The name, Green New Deal, references the New Deal of the 1930s that President Franklin Roosevelt implemented to aid Americans suffering in the Great Depression by embarking on huge government-led infrastructure projects.

"Today is the day that we choose to assert ourselves as a global leader in transitioning to 100 percent renewable energy and charting that path,” Ocasio-Cortez told reporters.

The resolution so far has 64 House co-sponsors and nine Senate sponsors - four of whom are Democratic presidential hopefuls for 2020. Senators Kamala Harris, Kirsten Gilibrand, Corey Booker and Elizabeth Warren co-sponsored the resolution.

Ocasio-Cortez said she will immediately begin to work on legislation that would "fully flesh out the projects involved in the Green New Deal."

Republicans have been quick to criticize the initiative, waving off any kind of proposal as heavy-handed. The Trump administration does not believe action on climate change is necessary and is focused on increasing production of oil, gas and coal on federal and private land.

"It’s a socialist manifesto that lays out a laundry list of government giveaways, including guaranteed food, housing, college, & economic security even for those who refuse to work," Republican Senator John Barrasso, chair of the Senate Environment and Public Works committee, said on Twitter.

The non-binding resolution outlines several goals for the United States, including meeting 100 percent of power demand from zero-emission energy sources like wind and solar within 10 years.

The plan also calls for new projects to modernize U.S. transportation infrastructure, cut carbon emissions from the manufacturing and agricultural sectors, make buildings and homes more energy efficient and increase land preservation.
