“Biden has been trying to take somewhat of a centrist tack, but he has to appease the core of the base if he’s going to win the primary,” said Jim Manley, who served as an aide to former Senate majority leader Harry M. Reid (D-Nev.). “They’ve needed to start throwing down some solid policies that will appease the left.”

To that end, Biden’s climate plan adopts the rhetoric — and at times, many of the actual policy proposals — of the Green New Deal resolution put forward this year by Rep. Alexandria Ocasio-Cortez (D-N.Y.) and Sen. Edward J. Markey (D-Mass.), which calls on the nation to eliminate its carbon footprint by 2030…

“Biden believes the Green New Deal is a crucial framework for meeting the climate challenges we face,” the document reads.

“It powerfully captures two basic truths,” it goes on. The first is that “the United States urgently needs to embrace greater ambition on an epic scale to meet the scope of this challenge” and the second is that “our environment and our economy are completely and totally connected.”
