The development of regulations to limit emissions from tyre wear depends on the development of an internationally recognised test procedure for measuring them. This issue is being examined by the UN ECE Particle Measurement Programme (PMP), which includes DfT officials, other international governments, and the automotive industry. DfT is one of the founders of PMP and has played a leading role since its inception.

To support the work of the PMP group, DfT commissioned a 3-year research project in February 2021 aimed at understanding better the measurement techniques, material properties and control parameters of non-exhaust emissions from road vehicles, which include tyre wear emissions. The findings of this project will also enable a comparative assessment of the particulate emitted by tyre wear in real driving conditions and exhaust fumes.

This project will inform policy and legislation aiming at reducing these emissions on a domestic and international level.
