38. The expert from EC, Chair of the task forces on brake emissions introduced GRPE-81-12 on an interim report on the activities on brake emissions. He detailed the achievements reached so far, including the definition of the brake emissions test cycles taken from the WLTC database, as part of the activities of the task force 1. He highlighted the on-going work on defining a procedure (task force 2) to measure brake dust emissions had been slowed down because of the Co-VID19 crisis and the difficulty to perform lab and other types of physical tests.

39. The representative from the UK highlighted non-exhaust are becoming a priority for come CPs, and that for example, microplastics from tyre wear represented a significant share of microplastics in the environment. The expert from EC explained that tyre wear was indeed a topic of high interest and that a research project was expected to be initiated soon at the European level to look closely at this issue. GRPE congratulated the excellent feedback on the brake emissions activities and encouraged regular updates on progress of this item that is part of GRPE priority list (Chapter XIV).
