Transportation accounts for nearly 1/3 of the US's greenhouse gas emissions and has been the fastest growing contributor. The vast majority of that comes from light and medium duty vehicles so personal cars and trucks. If we stopping building our cities to require driving and electrify where we can, we'll see a huge reduction in GHG emissions.
