GRPE has organized a workshop on on low- and zero-emissions heavy duty vehicles regulatory needs concurrent with this session. The workshop aims to explore the potential regulatory needs that could emerge with the wider adoption of alternative powertrains for heavy duty trucks and buses.
34. The representative from the EC, Chair of the IWG on PMP, introduced GRPE-83-21 giving a status report of the activities of the IWG on PMP. He explained the reasons for requesting to remove ECE/TRANS/WP.29/GRPE/2021/17 from the agenda. He detailed such request was due to diverging views on the possibility of sampling directly from raw exhaust, requiring additional tests to be performed over the 2021 summer.
35. The representatives from Japan, the UK and the EC introduced GRPE-83-11 as a request for authorization to develop a new UN GTR No. [XX] on brake PM and PN emissions. The representative from the US asked, given the ambitious timeline, if a PM/PN measurement procedure was already close to finalization. The representative from EC, leading the activities on non-exhaust emissions, clarified that rig test procedure was well advanced and added some issues such as regenerative braking, extreme brake events, were still being considered by the group.
36. GRPE requested the secretariat to submit GRPE-83-11, as reproduced in Annex XII to WP.29 and AC.3 for consideration and vote at their November 2021 sessions as request for authorization to develop a new UN GTR No. [XX] on brake PM and PN emissions.
37. The Chair of the IWG on PMP introduced GRPE-83-20 as updated terms of reference and rules of procedure for the IWG on PMP, detailing all the expected activities until June 2023. The Chair requested for information about expected completion for ultra-fine particulate under 23nm measurement procedure for light duty vehicles on the road. The Chair of the IWG on PMP informed this procedure was expected to be completed by June 2022.
38. He finally announced that, after more than 15 years as Chair of the IWG on PMP, other activities would prevent him for carrying on being a Chair of the IWG on PMP. The IWG on PMP nominated Barouch Giechaskiel, from the European Commission Joint Research Centre, as a new Chair of the IWG on PMP.
39. GRPE endorsed GRPE-83-20 and recognized the great work and achievements from Giorgio Martini as outgoing Chair of the IWG on PMP and congratulated Barouch Giechaskiel as the new Chair for the IWG on PMP.
