Maryland Clean Trucks Program Impact Analysis

This report is a comprehensive analysis of the impacts of zero-emission medium- and heavy-duty trucks on the environment, public health, industry, and the economy in Maryland. Commissioned by the Natural Resources Defense Council and the Union of Concerned Scientists, the document evaluates state-level requirements for manufacturers to increase sales of no- and low-emission trucks. The analysis encompasses all on-road vehicles registered in Maryland that exceed 8,501 pounds gross vehicle weight, detailing the current fleet's pollution contributions, which include significant greenhouse gas emissions and particulate matter. The report models two Clean Truck policy scenarios, projecting substantial net societal benefits from adopting California's Advanced Clean Truck rule. These benefits include reduced emissions, improved public health outcomes, and economic savings for fleet operators. The findings indicate that implementing these policies could lead to significant health improvements and economic advantages for Maryland residents, particularly in vulnerable communities affected by transportation emissions.
