Emissions-Focused Measures

Emissions-focused measures are those that directly target reductions in emissions, including greenhouse gas emissions, particulate matter, and smog-forming NOx emissions. There are a range of policies that can target this goal and can often create numerous co-benefits in the process. Policymakers can implement direct emissions standards, requiring that individual vehicles or fleets of vehicles reach certain emissions level per mile traveled. Alternatively, policymakers can design market-based policies that create an incentive to adopt technologies or practices that lower the targeted emissions.
