Bernie Sanders released a climate plan on Thursday that would cost $16.3 trillion during his tour of a Northern California town ravaged by wildfire.

The presidential hopeful called the town of Paradise a “wake-up call for our entire nation” to the dangers of a warming planet.

“It is expensive,” Sanders said at a climate-focused town hall near Paradise. “But the cost of doing nothing is far more expensive.”

The Vermont senator’s climate plan calls for the United States to move to renewable energy across the economy by 2050 and declare climate change a national emergency.

“Climate change is a major, major crisis for our country, and the entire world, and one of the manifestations of that crisis is what happened here,” the Vermont senator said as he walked through a burned-out mobile home park in Paradise.

While Sanders had already endorsed the Green New Deal, the sweeping Democratic proposal to combat climate change, and had teamed up with Rep. Alexandria Ocasio-Cortez of New York on climate legislation, his new plan provides the most detail yet on how he envisions the climate change moonshot taking shape if he is elected president.

Sanders describes his plan as a “ten-year, nationwide mobilization centered on equity and humanity” that would create 20 million new jobs.
