Progressives in the House and Senate plan to set down a marker Thursday for President Joe Biden’s infrastructure plans, introducing a $500 billion proposal to shift U.S. transportation away from fossil fuels.

Senator Elizabeth Warren and Representative Alexandria Ocasio-Cortez, two proponents of the Green New Deal, are behind the bill, joined by Senator Edward Markey of Massachusetts and Representative Andy Levin of Michigan. Their plan aims to accelerate the process of making the U.S. carbon neutral by 2050—a goal Biden campaigned on—by putting the money in the hands of state, local and tribal governments or transit authorities to make sweeping investments in public transit systems.
