Update on particle measurement program activities.

Proposal to revise the current mandate in order to respond to EU interest in further exploration of particle number emissions from spark ignition engines relating to particle size (reduction of the d50 cut off specification) and to emissions under rich operation conditions. The proposal further raises prospect for GTR transposition and/or work on particle emissions from tire/brake (friction material) wear.

UNECE “background note” providing information on developments in air pollution, the results of recent studies on the harmful effects of diesel exhausts, policy developments in the reduction of pollutant emissions to address health and environmental concerns.

Proposal to extend the mandate of the Informal Working Group on the Particle Measurement Programme.

UNECE report in response to World Health Organization concerns over vehicle emissions, in particular diesel particulates.

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

Position paper calling attention to transport-related particulate matter, including exhaust and non-exhaust particulates, and considering the negative impact on air quality inside motor vehicles due to shortcomings in ventilation and filtration systems.

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.

Update on the development of ISO 27891 Aerosol particle number concentration – Calibration of condensation particle counters.

Progress report on the European Metrology Research Programme.

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

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