This report finalizes reporting on the greenhouse-gas (GHG) emission impacts and cost-effectiveness of California’s Clean Vehicle Rebate Project in 2020. Fuel-cycle GHG emission reductions are estimated using an evolving methodology that is increasingly case-specific, including updated inputs that further tailor characterizations of baseline gasoline vehicles. Compared to new gasoline vehicles, we find GHG reductions from 37,201 rebated EVs to total roughly 900,000 metric tons of carbon-dioxide-equivalent emissions over 100,000-miles of driving.

In total, approximately 39% of the 2020 reductions are associated with “Rebate-Essential” participants, who were the most highly influenced by the rebate to purchase/lease. Approximately 67% of reductions from recipients of CVRP’s Increased Rebate for Low-/Moderate-Income households were Rebate Essential. Cost-effectiveness of Rebate-Essential reductions averages $234 per metric ton of GHGs abated.
