Brake wear emissions. PP012101 Pilot project - Feasibility study on reduction of traffic-related particulate emissions by means of vehicle mounted fine dust filtration
report
This pilot project investigates technologies to reduce brake particulate emissions in light duty (LD) and heavy-duty (HD) vehicles. It was assumed that market-ready brake particle filter systems were available, but market surveys revealed that only an active brake particle filter for LD vehicles and an ambient air filter, with no available systems for HD vehicles. Consequently, the project was re-scoped to validate the LD active brake particle filter, while focusing on understanding brake particle emissions for HD vehicles, including their composition, toxicity, and environmental impact. Measurement set-ups and methodologies were developed for both LD and HD. The measurement results confirmed significant reductions in particulate emissions for LD, while HD campaigns indicated insight into brake emissions, with highest levels during city driving. The ambient air filter system, tested on a bus, demonstrated potential for reducing particulate matter (PM) emissions. Lifecycle and cost-benefit analyses reveal the LD active brake particle filter system's benefits in reducing emissions and improving human health. A societal benefit of €1.7 billion is projected by 2050 and a Benefit-Cost Ratio of 1.31. Benefits decrease when accounting for climate impacts from increased energy use and vehicle weight.
