The Chair highlighted that GRPE would be the appropriate body to tackle those issues but also recognized the important role that IWG on Periodic Technical Inspection (PTI) had to make proposals to address the issues highlighted by the representative from CITA.

27. The expert from Austria supported the findings and the position from the expert from CITA. He shared the view that Type Approval (TA) and PTI are strongly connected and that activities to better link those two should start as soon as possible. The expert from Poland agreed that most air pollution was from older vehicles, and that fleet renewal must be accelerated. He acknowledged that PTI cannot capture all tampering as it stood, and that a more systematic use of Mini Portable Emission Measurement System (PEMS) might have helped solve the issue. The expert from OICA called for a holistic approach, that includes individual behavioural aspects to tampering.

28. The representative from EC stated that she was well aware of the issue and highlighted the fact that PTI tests had historically been developed elsewhere and included in TA legislation as Type II tests, as it required a simple and cheap test procedure. The secretariat reminded that all parties, including NGOs were allowed to submit proposals under the 1958 Agreement.

29. The Chair recalled that the mandate of GRPE also include legal provisions for the whole life of the vehicle and called for discussions on improvements to the PTI test to take place in the forthcoming sessions of GRPE.

31. The expert from OICA introduced GRPE-78-15 and summarized the workshop on the harmonization of heavy duty fuel economy measurements held by OICA earlier during the GRPE week. He thanked the secretariat for the assistance in organizing the event. He highlighted the high level of interest shown by all parties involved in the workshop.

32. The Chair encouraged GRPE to start activities in this topic. He suggested a follow-up workshop in January 2020 to gauge progress. The expert from OICA confirmed activities on this topic is of high priority to them, and he confirmed his willingness to organize such a workshop prior to the January 2020 session of GRPE.

50. She explained that the ongoing work on UN GTR on Determination of Electrified Vehicle Power (DEVP) had been delayed due to unexpected and inconsistent results obtained during the validation testing of the power measurement approaches, mainly regarding its reproducibility and repeatability. The delay in developing the UN GTR was expected to be at least half a year, and IWG had still not agreed on a new timeline for developing the draft proposal.

51. She reported on the activity on battery durability, where the activities had progressed well. She added that a consensus on the next steps for this research activities was still to be found.

52. She informed GRPE that IWG on EVE had made a presentation to the Cleaner Electricity Production (CEP) expert group of the Energy Division of ECE to seek their partnership on the project to assess upstream emissions from electric vehicles. The Secretary of GRPE agreed to follow-up with colleagues from ECE Energy Division.

53. GRPE reviewed and endorsed the request for authorization to develop the provisions on DEVP as a new UN GTR (ECE/TRANS/WP.29/2019/33), to be adopted during the March 2019 session of WP.29.

54. The representative from EC highlighted that the work done by IWG was very important, and that the activities should be undertaken at GRPE. She insisted on further efforts to finish the activities on time or risk that activities would have to be held at the national / regional level.

55. GRPE acknowledged the progress of IWG on EVE and encouraged the group to deliver on the important activities that are needed in many Contracting Parties. GRPE noted the request for a meeting room for half a day during the GRPE week in May 2019.

Proposal to clarify the meaning and use of “peripheral devices”.

56. The expert from EC with the support of the expert from UK introduced ECE/TRANS/WP.29/GRPE/2019/5 clarifying the definition of peripheral devices.
