In a major upset on Tuesday night, Alexandria Ocasio-Cortez, a 28-year-old Latina democratic socialist from the Bronx, beat out the longtime US representative Joe Crowley in the New York primaries. In the overwhelmingly Democratic district, she is practically certain to win a seat in Congress during the general election in November.

Ocasio-Cortez’s climate-change platform would become the most progressive of that of any sitting Congressperson in the Democratic party—and her primary victory catapults that platform into the mainstream.

“We need more environmental hardliners in Congress,” she told In These Times magazine earlier this week. “We need a Marshall Plan for renewable energy in the United States. The idea that the Democratic Party needs to be moderate is what’s holding us back on this.”

Ocasio-Cortez wants to make the US run 100% on renewable energy by 2035. Scientists warn that the window of opportunity for staving off dangerous levels of climate change is rapidly closing, and dramatically (and quickly) reducing emissions is the most direct route to avoiding potential environmental catastrophe. Rapidly decarbonizing the US economy by completely shifting to renewables is the best and maybe only way to actually make a difference in climate-change mitigation; any milder approach will almost certainly lead us to miss that window.

The Huffington Post points out that Ocasio-Cortez’s 100%-renewable plan puts her in agreement with a coalition of US mayors who have committed to the goal of complete decarbonization within their own cities. But Ocasio-Cortez, who has an economics degree, also couples that plank with an economic plan she is calling the Green New Deal.

“The Green New Deal we are proposing will be similar in scale to the mobilization efforts seen in World War II or the Marshall Plan,” she told the Huffington Post. In short, Ocasio-Cortez’s Green New Deal would temporarily redirect the US economy towards avoiding catastrophic climate change. “We must again invest in the development, manufacturing, deployment, and distribution of energy, but this time green energy,” she said.
