RFP 25RD005 Measurement and Characterization of Brake-Wear Emissions from Zero-Emission Vehicles

This contract funds a 36‑month research‑services agreement to measure and characterize brake‑wear emissions from zero‑emission vehicles (ZEVs) and conventional vehicles. The work includes selecting representative fleet vehicles, developing and validating brake‑dynamometer test procedures, collecting real‑world braking data, conducting laboratory emissions testing, analyzing chemical composition and toxicology, deriving emission factors for use in CARB’s emissions inventory models, and delivering a simulation tool for estimating brake‑wear emissions across vehicle fleets. The effort will produce multiple technical reports, a final ADA‑compliant report, and a public research seminar. • Develop and validate laboratory brake‑dynamometer protocols that incorporate ZEV regenerative‑braking characteristics. • Generate a comprehensive testing matrix, conduct emissions testing, and produce emission‑factor datasets for integration into the EMFAC model. • Deliver a calibrated emissions‑simulation model, full data packages, and a public dissemination seminar.
