Diesel Emissions Reduction Act of 2025

# Diesel Emissions Reduction Act of 2025 Summary **What the Bill Does** The Diesel Emissions Reduction Act of 2025 aims to reduce pollution from diesel engines, which are commonly used in trucks, buses, construction equipment, and other heavy machinery. The bill would likely fund programs and incentives to help replace or upgrade older diesel vehicles and equipment with cleaner alternatives, similar to previous versions of this legislation that Congress has passed. This would improve air quality and reduce greenhouse gas emissions from the diesel sector. **Who It Affects** The bill would impact businesses and government agencies that operate diesel vehicles and equipment, particularly trucking companies, transit systems, construction firms, and agricultural operations.

It could also benefit communities near highways, ports, and industrial areas that experience higher air pollution from diesel emissions. Equipment manufacturers and companies providing emission-reduction technology would likely be affected as well. **Current Status** As of now, HR 2140 is in committee, meaning it has been introduced but has not yet been debated or voted on by the full House of Representatives. The bill was sponsored by Representative Doris Matsui (D-CA).
