ANALYZING THE IMPACT OF THE INFLATION REDUCTION ACT ON ELECTRIC VEHICLE UPTAKE IN THE UNITED STATES

The report finds that the IRA will significantly accelerate the adoption of electric vehicles (EVs) and zero-emission vehicles (ZEVs) in the US, potentially exceeding the Biden administration's 2030 targets. However, the authors argue that these incentives alone are insufficient to meet the US Nationally Determined Contribution or the Paris Agreement goals, necessitating additional federal GHG standards and investments in infrastructure and manufacturing.

• The IRA is projected to significantly increase electric vehicle (EV) sales shares for light-duty vehicles (LDVs) by 2030, ranging from 48% to 61% depending on the scenario, and increasing to 56%–67% by 2032.
• For heavy-duty vehicles (HDVs), the IRA is estimated to drive ZEV sales shares to between 39% and 48% by 2030, and 44%–52% by 2032.
• The IRA tax credits are expected to reduce the purchase costs of light-duty EVs by an average of $3,400 to $9,050 over the 2023–2032 period.
• The report concludes that the IRA alone is insufficient to meet the US Nationally Determined Contribution (NDC) or the goals of the Paris Climate Agreement to limit global warming to well below 2 degrees Celsius.
• Battery electric vehicles (BEVs) are projected to dominate the heavy-duty ZEV transition, while hydrogen fuel cell electric vehicles (FCEVs) will play a very limited role, with less than 1% penetration in all truck classes.
• The analysis suggests that to deliver substantial climate benefits beyond the baseline, federal GHG standards would need to drive electrification rates above 50% for LDVs and above 40% for HDVs by 2030.
• Non-financial barriers, specifically manufacturing lead times and charging infrastructure development, are identified as major challenges, particularly for the heavy-duty sector.
• The IRA is expected to accelerate the timeline for upfront price parity between BEVs and internal combustion engine (ICE) vehicles to the 2023–2025 timeframe, which is 3–5 years sooner than without the incentives.
