67. The representative of the European Commission, Chair of the IWG on PMP, introduced GRPE-90-28, giving a status report of the activities of the IWG on PMP. The representative of France requested further information about the inclusion of ultrafine particles (PN10) into exhaust particle measurement procedures.

68. The Chair of the IWG on PMP clarified the technical work is finalized, and inserting provision to include PN10 in UN Regulations Nos. 49, 154, 168 or others was mostly administrative and needed agreement with contracting parties involved. The representative of the EC indicated the latest Euro 7 proposal required PN10, and the preamble of the legal act gave a mandate to the EC to align concerned UN Regulations with EU legislation. He showed willingness to address such issue in a timely manner to be aligned with the Euro 7 implementation timeline.

69. The representative of the Netherlands introduced GRPE-90-30. The Chair of PMP clarified that the group did not have any health-effect experts participating at the moment. To date, particular mass and particle number had been recognized as important proxies to health effect of particle emissions. He added that additional expertise would be needed in PMP to tackle heath effect. He further clarified that total particle mass and wear are included in UN GTR No. 24. The representative of the EC informed that the latest draft of Euro 7 legislation included a placeholder for a particle number limit for brake emission for 2030. He said the EC is required to prepare a report on the topic by the end of 2027.

70. The representative of the UK acknowledged the importance for GRPE to have a platform to discuss these topics early in prepare further legislative requirements. He added that there is mixed evidence today and so a dedicated platform where updated knowledge would be shared and discussed could play an important role to be able to act in a timely manner. The Chair proposed to keep the topic in the emissions list of GRPE (GRPE-87-55-Rev.1) to discuss regularly discuss the topic in GRPE.
