84. Referring to WP.29-160-19-Rev.1, the secretariat informed the World Forum on the emissions of air pollutants due to vehicles and engines, focusing on diesel exhaust emissions and providing an overview of the WP.29 activities carried out in this field. Following a recommendation by WP.29 in November 2012, GRPE had considered earlier versions of this document in January and June 2013. The secretariat clarified that WP.29-160-19-Rev.1 incorporates and addresses additional comments received after the June 2013 session of GRPE. The GRPE Chair supported the document. The World Forum endorsed WP.29-160-19-Rev.1 and agreed that the document should become part of the contribution of the Transport Division to the UNECE position on diesel exhaust emissions.

18. The representative of the Russian Federation introduced a document (WP.29-160-39) containing data on release of particulates by transport vehicles that included not only engine emissions, but also tyre wear and brake pads wear. The Committee recommended referring this document to GRPE for consideration by its IWG on Particulate Matter Programme (PMP) and to GRB and GRRF for information and requested the secretariat to take the necessary actions.

26. Recalling the submission of GRPE-65-20, WP.29-160-39, WP.29-161-22 and GRPE-68-10 on tyre and brake wear and vehicle indoor air quality, the expert from the Russian Federation introduced GRPE-69-03 with further test and research results. He underlined the evidence that tyre wear would contribute to air pollution not only with solid particulates but also with gaseous pollutants. He announced that, to address this issue, the standard GOST R 51206-2015 on cabin air filters and purifiers was under development.

27. The Chair of the IWG on PMP provided an overview of the latest activities of the IWG (GRPE-69-25) focusing (i) first on the exhaust emissions, in particular on the 23 nm cut-off size confirmation given the state of technology as well as the development of a robust procedure to measure particles down to 10 nm in case of future needs, (ii) then on the particle emissions during regeneration and the particle emissions from Non-Road Mobile Machinery. He reported that the Group had addressed (GRPE-69-24) the concerns expressed in GRPE-69-03 and proposed a possible road map on how to proceed further with the issue of particles from tyre and brake wear (GRPE-69-23).

28. GRPE acknowledged the information provided by the IWG and the Russian Federation, endorsed in principle the roadmap proposed and requested the secretariat to reserve a room for a meeting prior to the January 2015 GRPE session.

43. The expert from the Russian Federation introduced GRPE-69-03 while discussing item 7 on Particulate Measurement Programme (see para. 26).

30. The expert from the Russian Federation presented GRBP-70-07 on the emissions of hazardous substances and particulate matters caused by wear of tyres and roadway, which contaminates urban atmosphere. GRBP took note of this information as well as of the position of the European Tyre and Rubber Manufacturer’s Association (ETRMA) (GRBP-70-16). The expert from EC mentioned the ongoing European Union study on the subject. The Chair acknowledged the importance of this issue and recalled that it had been allocated to the Working Party on Pollution and Energy (GRPE) and its Informal Working Group on Particle Measurement Programme (IWG PMP).
