ERM was retained by the Environmental Defense Fund (EDF) to perform an assessment of projected “business-as-usual” medium- and heavy-duty (M/HD) zero emission vehicle (ZEV) sales and in-use vehicles within the US through 2029.

ERM’s memo describes the analytical methodologies and data sources used to develop the baseline assessment as well as a summary of the key results. With the Inflation Reduction Act (IRA) being signed into law, EDF engaged ERM to update the previously completed assessment to incorporate the impacts of IRA funding as well as the ZEV credit program.
