Presidential candidate Sen. Elizabeth Warren (D., Mass.) said Wednesday that her administration would mandate that any new buildings built from 2028 onwards must be carbon neutral.

"What scares me is every time you go back to the scientists, they tell you two things. It's worse than we thought and we have less time," Warren said during an appearance on MSNBC's Morning Joe. "That means we've got to be willing to do things, for example, like regulation. By 2028, no new buildings, no new houses, without a zero carbon footprint."

Warren also backed regulation that would make light-duty trucks and cars carbon neutral by 2030, and all electricity production carbon neutral by 2035. Additionally, Warren said she would prohibit any new drilling either on federal lands or offshore, and promised to make "environmental justice" a major focus of her fight against climate change.

"We also need to make environmental justice really at the heart of our climate plan," Warren said. "A central part of the plan for me is I want to put a trillion dollars into cleaning up the places that collectively we have destroyed as a nation and bringing them back."

During a climate town hall in September, Warren said she would end license renewals of existing nuclear plants and stop the building of new ones.
