Domestic Policies to Reduce the Near-Term Risks of Climate Change
Heavy-duty diesel engines are a key source of emissions of black carbon, one of the major short-lived climate pollutants. In a policy brief, Domestic Policies to Reduce the Near-Term Risks of Climate Change, C2ES recommends that the EPA develop expanded incentive-based programs to retrofit or accelerate the replacement of existing heavy-duty diesel engines to reduce these emissions.

The Center for Climate and Energy Solutions seeks to inform the design and implementation of federal policies that will significantly reduce greenhouse gas emissions. Drawing from its extensive peer-reviewed published works, in-house policy analyses, and tracking of regulations and legislative proposals, the Center provides research, analysis, and recommendations to policymakers in Congress and the Executive Branch.
