Transportation Secretary Pete Buttigieg and Energy Secretary Jennifer Granholm stressed the importance of their agencies working together under a new national blueprint released Tuesday that aims to eliminate greenhouse gas emissions from the transportation sector by 2050.

Buttigieg said during the Transportation Research Board’s annual meeting in Washington, D.C. on Wednesday the Biden administration is focused on working with states to build out a national EV charging network and ensuring such infrastructure is added in rural areas, at multifamily dwellings and low-income communities.

To accomplish this, the blueprint tries to meet people where they are: People tend to drive longer distances in rural areas, he said, stressing the potential gas savings, and they live in single-family housing, allowing them to charge at home.

But to achieve those goals, the two agencies must work together.
