WARREN: "There are just three industries in America that produce together about 70 percent of all our carbon emissions. You push those three industries and all of a sudden the world looks different. So by 2028, what I plan is that all new building, housing, new buildings will have zero carbon footprint. They don’t — no more carbon emissions from our buildings. By 2030, all new cars and light duty trucks, zero carbon footprint. And by 2035, the production of electricity, zero carbon footprint."
