Hillary Clinton unveiled her most detailed proposals on climate change since becoming a presidential candidate, calling for moving the economy on “a path towards deep decarbonization by 2050” and “enough clean renewable energy to power every home in America” by 2027. 

Progressives have been badgering Clinton to take a strong stance on climate change. Earlier this month in New Hampshire a group of activists disrupted her first town hall in the state, demanding she pledge to end extraction of fossil fuels on public lands.

The plan is the most specific that Clinton’s made yet as a candidate on how she would combat climate change, though she has often been outflanked on the left by her Democratic challengers, Vermont Sen. Bernie Sanders and former Maryland Gov. Martin O’Malley.

But on Sunday evening she won praise from billionaire climate-change activist Tom Steyer, who last week called on presidential candidates to embrace a goal of generating 50 percent of the nation’s power from carbon-free sources by 2030 with an eye toward “a completely clean energy economy” by 2050.
