Copper-Free Brake Initiative

On January 21, 2015, EPA, states, and the automotive industry signed an agreement to reduce the use of copper and other materials in motor vehicle brake pads. The agreement calls for reducing copper in brake pads to < 5 percent by weight in 2021 and 0.5 percent by 2025. In addition to copper, this voluntary initiative reduces mercury, lead, cadmium, asbestiform fibers, and chromium-six salts in motor vehicle brake pads.

The Initiative will decrease runoff of these materials from roads into the nation’s streams, rivers, and lakes. Copper from stormwater runoff can affect fish, amphibians, invertebrates, and plants.

This initiative includes:

This webinar, held on October 6, 2021, explores how this voluntary initiative and these partnerships developed, the roles of the signatories, and the progress made so far. Speakers highlight lessons learned and considerations for organizations considering future voluntary source control partnerships.

Numbers on Copper Reductions

California and Washington already passed requirements to reduce these materials in brake pads.

Prior to these requirements, fine dust from vehicular braking released an estimated 1.3 million pounds of copper into California’s environment in 2010 and about 250,000 pounds into Washington’s environment in 2011. Estimates for California show as much as a 61 percent reduction of copper in urban runoff due to changes in brake pad composition.

In addition to EPA, the Environmental Council of the States, and eight industry groups signed the initiative:
