Environmental and Propulsion Performance Requirements for L-category Vehicles (EPPR)
Reports to GRPE

The EPPR informal group works on motorcycle and related vehicle category emissions, including the Worldwide Motorcycle Emissions Test Cycle (WMTC under GTR 2), on-board diagnostics (GTR 19), and the durability of emissions-control devices. The group published revised Terms of Reference on 2 December 2020.
