Discussion paper outlining concerns over particulates originating from tire erosion and suggesting a need for global regulatory provisions to limit such environmental risks.

Summary of results from research by the Russian Federation into non-exhaust particle emissions from motor vehicles.

Review by the Particle Measurement Program expert group of research on airborne particles from non-exhaust sources, especially particulates from brake friction materials and tires. The PMP group is evaluating whether such non-exhaust particulates represent an appropriate and feasible concern for further consideration as a possible regulatory issue.

Review of main issues concerning the measurement of sub-23 nm particles in vehicle exhaust, including work on NRMM vehicles.

Background paper in support of the Russian proposal to consider further sources of harmful emissions, especially particulates, such as from tires and brake pads.

Discussion paper on non-tailpipe vehicle emissions, especially related to air quality and suspended particulates along roadways. This subject includes particulates from tire and brake wear.
