Carbon-reduction policies significantly improve air quality.
Now I want to be clear: I am inspired by the Administration’s commitment to phasing out carbonemissions. We do have a climate crisis that needs to be addressed. The US transportation sector accounts for the largest portion of US greenhouse gas emissions, and I firmly believe it is a human right to breathe clean air.
