IMPLEMENTING THE INFLATION REDUCTION ACT: A ROADMAP FOR FEDERAL AND STATE TRANSPORTATION POLICY

The report analyzes the IRA's transportation incentives, including tax credits for new and used EVs, commercial vehicle credits, and charging infrastructure support. Through three modeling scenarios (Low, Moderate, High), it estimates that the IRA can increase passenger EV sales shares to 34% (Moderate) or 39% (High) by 2030 compared to a 29% business-as-usual baseline. It highlights that while commercial and light-duty truck adoption will see significant boosts, passenger EV adoption may be limited in the near term by stringent eligibility requirements regarding North American assembly and sourcing from 'entities of concern'. The authors argue that the IRA is a foundational step but insufficient alone to meet 1.5°C climate goals, recommending complementary EPA tailpipe standards, state-level clean vehicle mandates, and strategic electric grid investments.

• The IRA's transportation incentives are insufficient on their own to reduce greenhouse gas emissions at the rate required for a 1.5-degree Celsius climate scenario, necessitating further regulatory and policy actions.
• Modeling indicates that under a 'Moderate Scenario', where 50% of new EVs meet sourcing requirements by 2032, the sales share of battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) would rise from 29% in a business-as-usual scenario to 34% by 2030.
• In a 'High Scenario' where 100% of vehicles meet sourcing and tax credit requirements by 2032, EV deployment is projected to reach 39% in 2030, a 10% increase over the business-as-usual baseline.
• Commercial vehicle electrification is expected to see a more significant boost than passenger vehicles because light- and medium-duty trucks are not subject to the same stringent eligibility requirements as passenger cars.
• Near-term passenger EV adoption may be hindered by strict eligibility rules, specifically the requirement that vehicles be assembled in North America and the restrictions on materials sourced from 'foreign entities of concern', such as China.
• The IRA introduces a first-ever tax credit for used EVs, providing 30% of the sale price up to $4,000 for vehicles with a final sale price not exceeding $25,000, aimed at increasing access for lower- to middle-income households.
• The IRA significantly increases the commercial tax credit for EV charging infrastructure, raising the cap from $30,000 per location to $100,000 per charger to encourage private investment in DC fast charging.
• Achieving a 90% clean grid and 100% electric new vehicle sales by 2035 would increase electricity demand growth by approximately 2% per year through 2050, requiring an average of 105 GW of new wind and solar and 30 GW of new battery storage annually for 30 years.
