2. The Chief of the Vehicle Regulations and Transport Innovations Section, Mr. W. Nissler, informed GRPE about the abolishment of four General Service (G) posts within the United Nations Economic Commission for Europe (UNECE) as decided by the UN General Assembly on 23 December 2015. He explained that a G post was abolished in the Vehicle Regulations and Transport Innovations Section since 1 January 2016 due to the immediate retirement of the current incumbent. He warned that this unfortunate situation may affect future services to be provided by the Section.

3. The Chair announced that he will not be in the position to continue chairing GRPE as of year 2017 and, therefore, he will no longer be a candidate at the next GRPE session in June 2016 for the election of officers for the year 2017.

1. Adoption of the agenda

4. GRPE adopted the provisional agenda prepared for its seventy-second session (ECE/TRANS/WP.29/GRPE/2016/1 and Add.1), as updated and consolidated in GRPE‑72-17-Rev.1, including the informal documents tabled for the session. GRPE noted GRPE-72-01, on the organization of GRPE Informal Working Group (IWG) meetings held during the week.

2. Report on the last sessions of the World Forum for Harmonization of Vehicle Regulations (WP.29)

7. The secretariat introduced GRPE-72-08 and reported on relevant GRPE items discussed during the 166th and 167th sessions of the World Forum. For more details, see ECE/TRANS/WP.29/1116 and ECE/TRANS/WP.29/1118. GRPE noted the exchange of information on the Volkswagen case that had taken place at the November 2015 session of WP.29.

GRPE-72-08 | Highlights of the last WP.29 sessions for the 72nd GRPE session Highlight from the June and November 2015 WP.29 related to the work of the GRPE.

8. The expert from OICA stated that the information in GRPE-72-08 on the transposition process of the Global Technical Regulation (GTR) on Worldwide harmonized Light vehicles Test Procedure (WLTP) into a new Regulation could be misleading. He clarified that WP.29 agreed at its November 2015 session to include a highest level of stringency in the new Regulation on WLTP, but without any ranking order between all other lower levels.

3. Light vehicles
3. (a) Regulations Nos. 68, 83, 101 and 103

9. The expert from EC introduced ECE/TRANS/WP.29/GRPE/2016/4 aimed at correcting the calculation of the vehicle coast down resistance to progress force in the 07 series of amendments to Regulation No. 83.

GRPE/2016/4 | Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83 Proposal to correct the calculation of the resistance to progress force. This proposal was amended during GRPE discussions to cover the 06 and 07 series of amendments to UN R83.

10. The expert from OICA drew the attention to the confusion and administrative burden that could be created by the proposal if requirements were not aligned between the 06 and 07 series of amendments to Regulation No. 83, as well as with Regulation No. 101. He expressed his concern on the possible impact this may have on the CO2 emissions type approval value and, thus, on the correlation program between WLTP and the New European Driving Cycle (NEDC). He suggested considering amendments to the 06 and 07 series of amendments to Regulation No. 83 and to Regulation No. 101 as an entire package at the next GRPE session.

GRPE/2016/4 | Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83 Proposal to correct the calculation of the resistance to progress force. This proposal was amended during GRPE discussions to cover the 06 and 07 series of amendments to UN R83.

11. The Chair of GRPE suggested adopting the proposal not only for the 07 series but also for the 06 series of amendments to Regulation No. 83 since the text and the paragraph numbering were the same in both cases. The experts from the Netherlands, UK and T&E expressed their support to ECE/TRANS/WP.29/GRPE/2016/4. The expert from EC volunteered to review Regulation No. 101 to align it with this proposal at the next GRPE session in June 2016. He also clarified that the correlation program between WLTP and NEDC ensuring that both tests were properly coupled would not be affected by this proposal.

GRPE/2016/4 | Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83 Proposal to correct the calculation of the resistance to progress force. This proposal was amended during GRPE discussions to cover the 06 and 07 series of amendments to UN R83.

12. GRPE adopted ECE/TRANS/WP.29/GRPE/2016/4 with the following correction:
Title of the document, amend to read:
“Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83 (Emissions of M1 and N1 vehicles).”

13. GRPE requested the secretariat to submit it to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2016 sessions as draft Supplement 7 to the 06 series of amendments and draft Supplement 3 to the 07 series of amendments to Regulation No. 83.

GRPE/2016/4 | Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83 Proposal to correct the calculation of the resistance to progress force. This proposal was amended during GRPE discussions to cover the 06 and 07 series of amendments to UN R83.

14. The expert from Italy presented GRPE-72-03 on amendments to Regulation No. 83 to introduce the possibility to inhibit the driver inducement system of rescue and police service vehicles.

15. The expert from OICA supported the proposal and its alignment with Regulation No. 49. The expert from the Netherlands agreed in principle with the proposal but expressed a reservation to further examine the possible drawbacks such as the exemption proposed for specific vehicles when becoming publicly available. The expert from T&E supported this reservation and underlined the need to reinsert the initial system when these vehicles abandon the rescue and police services in the second hand market.

16. The Chair invited the expert from Italy to submit an updated proposal as an official document at the next GRPE session taking into account the comments received.

GRPE-72-03 | Proposal for amendments to the 06 and 07 series of amendments to Regulation No. 83 UN Regulations Nos. 49 and 83 include provisions for a "driver inducement system" that alerts drivers of low reagent levels (urea, etc.) critical to correct emissions control performance and eventually prevents vehicle operation if the reagent tank is empty. Under UN R49 (para. 5.2), rescue, police, and other emergency/special use vehicles are exempted from this requirement. This proposal would extend the same treatment under UN R83.

17. The expert from OICA presented GRPE-72-05 reproducing ECE/TRANS/WP.29/2016/28 aimed at reintroducing a sentence that was inadvertently deleted out in the original proposal and then in ECE/TRANS/WP.29/2015/57 adopted at the 166th session of WP.29. He recalled that ECE/TRANS/WP.29/2016/28 had been already submitted by the secretariat to WP.29 and AC.1 for consideration at their March 2016 sessions, subject to the endorsement of GRPE at this session, to reintroduce the sentence.

18. The expert from Germany agreed with ECE/TRANS/WP.29/2016/28 and announced the intention of Germany to submit a proposal at the next GRPE session to further improve the requirements on the total number of failures simulated when testing the malfunction indicator.

19. GRPE endorsed ECE/TRANS/WP.29/2016/28 to be considered by WP.29 and AC.1 at their March 2016 sessions.

GRPE-72-05 | Proposal to amend WP.29/2016/28 (Supplement 2 to the 07 series of Regulation No. 83) Proposal to clarify that no more than four malfunction-indicator failures shall be simulated for type approval.
WP.29/2015/57 | Proposal for Supplement 1 to the 07 series of amendments to Regulation No. 83 Proposal to update the on-board diagnostics (OBD) requirements, to delete the definition of “vehicles designed to fulfil specific social needs” in line with the Euro 6 stages of European Union Regulation (EC) No. 715/2007 and implementation Regulation (EC) No. 692/2008, and to clarify the wording of transitional provisions and align them with the General Guidelines for UN Regulatory Procedures and Transitional Provisions in UN Regulations (ECE/TRANS/WP.29/1044/Rev.1). In addition, the proposed wording would allow Contracting Parties not to accept UN type-approvals if the requirements specified in the 07 series of amendments are not met.
WP.29/2016/28 | Proposal for Supplement 2 to the 07 series of amendments to Regulation No. 83 Proposal to correct the inadvertent deletion of a sentence in by WP.29/2015/57 adopted at the 166th session of the World Forum for Harmonization of Vehicle Regulations (WP.29).

20. The expert from EC presented GRPE-72-14 and GRPE-72-15 aimed at providing clarifications and correcting errors to the 06 and 07 series of amendments to Regulation No. 83 respectively. He confirmed that there was no need to modify the 05 series of amendments.

21. GRPE agreed in principle with both proposals and requested the secretariat to combine them in a single document to be distributed with an official symbol at the next GRPE session.

GRPE-72-14 | Proposal for amendments to the 06 series of amendments to Regulation No. 83 Proposal from the European Commission to provide clarifications and correct errors in the 06 series of amendments to Regulation No. 83.
GRPE-72-15 | Proposal for amendments to the 07 series of amendments to Regulation No. 83 Proposal from the European Commission to provide clarifications and correct errors in the 07 series of amendments to Regulation No. 83.
3. (b) Global Technical Regulation No. 15 on Worldwide harmonized Light vehicles Test Procedures (WLTP)

22. The Vice-Chair of the IWG on WLTP reported on the progress made by the group (GRPE-72-19). He highlighted the conclusion of the work under Phase 1B after having submitted to GRPE the corresponding amendments to GTR No. 15 and the technical report to be considered at this session.

23. The expert from EC presented ECE/TRANS/WP.29/GRPE/2016/3 proposing amendments to GTR No. 15 as a result of Phase 1B activities of the IWG on WLTP. He provided some background information on Phase 1A and on the main objectives of Phase 1B. He explained the technical topics addressed by ECE/TRANS/WP.29/GRPE/2016/3 with regard to conventional Internal Combustion Engine (ICE) vehicles, electrified vehicles, alternative pollutants and other improvements of the provisions of GTR No. 15.

24. The expert from OICA presented GRPE-72-09-Rev.2 introducing editorial corrections and improvements to the text of ECE/TRANS/WP.29/GRPE/2016/3 that had been identified since the last IWG meeting held in Tokyo in late September 2015. He mentioned that OICA accepted the task to collect and to consolidate all amendments to ECE/TRANS/WP.29/GRPE/2016/3 since the drafting coordinator could not be funded any longer by the Contracting Parties. He introduced GRPE-72-10-Rev.2 as a consolidated version of ECE/TRANS/WP.29/GRPE/2016/3 including all the modifications laid out in GRPE-72-09-Rev.2.

25. The expert from EC presented the technical report on the further development of WLTP (GRPE-72-02-Rev.1). He clarified that the technical report contained the development of the test procedure combining both Phase 1A and Phase 1B activities. He also mentioned that the test cycle development under Phase 1A had been considered in the technical report provided for the original version of GTR No. 15 and it was again referred to in GRPE-72-02-Rev.1.

GRPE-72-02/Rev.1 | Technical report on the development of GTR No. 15 on WLTP including Phase 1b Technical report prepared by the WLTP informal group to accompany the amendment to GTR No. 15 on light vehicle emissions, detailing the development and intentions of the amendments.

26. GRPE adopted GRPE-72-10-Rev.2 as reproduced in Addendum 1 to this report and requested the secretariat to submit it to WP.29 and the Executive Committee of the 1998 Agreement (AC.3) for consideration and vote at their June 2016 sessions as draft Amendment 1 to GTR No. 15. GRPE also adopted the technical report (GRPE-72-02-Rev.1) as reproduced in Addendum 2 to this report and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2016 sessions.

27. The Vice-Chair of the IWG on WLTP informed GRPE about the new leading team and the structure of task forces for the Phase 2 of the development of GTR No. 15 (GRPE-72-19). He presented GRPE-72-20 listing the working items and proposing a work plan in two steps (Phase 2A and Phase 2B). He explained that Phase 2 activities had already been initiated since AC.3 had endorsed the extension of the mandate at its November 2015 session. He mentioned that different approaches were being considered at this stage for evaporative emissions requirements with the aim to submit a proposal at the January 2017 GRPE session. He underlined the need of close collaboration with the IWG on Electric Vehicles and the Environment (EVE) during Phase 2.

GRPE-72-20 | WLTP Phase 2 working items and schedule Status of the WLTP informal group discussions on the Phase 2 development of GTR No. 15.

28. For the sake of clarity and simplicity in the application of regulations, the secretariat recommended developing new GTRs for evaporative emissions and On-Board Diagnostic systems (OBD) rather than new annexes to GTR No. 15. The expert from OICA highlighted that the separation of GTRs for different topics made the 1998 Agreement more attractive as it facilitated the transposition into national/regional legislation. The expert from India expressed the same opinion and referred to the split of GTRs because of different fuels and durability testing under the work of Environmental and Propulsion Performance Requirements (EPPR) for L-category vehicles as a good example to be followed. The expert from EC expressed her preference for splitting GTRs for different topics.

29. GRPE recommended in principle developing new GTRs dealing specifically with evaporative emissions and OBD, subject to the reconfirmation of this approach at the next meeting of the IWG on WLTP.

30. The expert from EC presented GRPE-72-18 on the transposition of GTR No. 15 into the legislation of the European Union. He informed GRPE about the progress made on the development of a new European Regulation, which was expected to replace the New European Driving Cycle (NEDC) in 2017 and which had a specific annex based on GTR No. 15 adapted to the European requirements.

31. The expert from EC continued his presentation (GRPE-72-18) on the transposition of GTR No. 15 into new Regulations annexed to the 1958 Agreement. He underlined the agreement of WP.29 at its November 2015 session on developing a new Regulation on WLTP with one top level (highest stringency) and other different levels of stringency below that top level. He recalled that the top level (Level 2) would correspond to the most stringent combination of regional requirements, whereas the levels below (Level 1a, Level 1b, etc.) would correspond to a specific national or regional legislation in terms of emission limits as well as region-specific technical and administrative requirements. He showed a possible structure of a new Regulation on WLTP and he highlighted the different parts (e.g. Annexes on approval marks and the communication form) that should enable distinction between the different levels. He introduced a possible structure of a second new Regulation that would complement the Regulation on WLTP (type 1 test only) by referring to the relevant parts of Regulation No. 83 on other test types. As the technical sponsor for these activities, he sought the advice of GRPE on the best way to move forward.

32. The expert from OICA underlined the need of Level 2 to be used for the Universal International Whole Vehicle Type Approval (U-IWVTA) as it would be the only level subjected to mutual recognition between all Contracting Parties to the 1958 Agreement applying the Regulation. He highlighted the complexity of defining Level 2 because of the different factors needed to be taken into account when defining the highest stringency (e.g. emissions limits, test, fuel, vehicle size and technology).

33. The Chair of GRPE mentioned that including Level 2 directly in the original version of the new Regulation on WLTP together with the levels below (Level 1a, Level 1b, etc.) could be a possible alternative to introducing Level 2 as a new series of amendments to the Regulation. The expert from EC emphasized the need of starting with the levels below to fill the gap in the European legislation in due time by 2017, whereas Level 2, currently artificial and likely to be time consuming to be defined due to its complexity, could be developed later on towards global harmonization. The secretariat reminded that the latest series of amendments to a Regulation (or its original version in the absence of series of amendments) were always subject to mutual recognition according to the 1958 Agreement.

34. GRPE endorsed the approach to focus first on the levels below (Level 1a, Level 1b, etc.) when developing the new Regulation on WLTP, while having in mind the need of Level 2 for IWVTA. GRPE agreed to further investigate the best way to integrate all levels in the new Regulation on WLTP and to resume discussion at the next GRPE session in June 2016.

35. The Chair of GRPE recommended that the structure of the new Regulation on WLTP should ensure the modular approach to take into account different levels. The expert from OICA was of the opinion that separation of modules could be helpful. The secretariat recalled the existence of safety Regulations structured according to one of the following options: a) modular approach in form of annexes corresponding to each of the levels, or b) single structure integrating the specifications of each level through tables in all relevant paragraphs.

36. The expert from EC wondered whether Japan would follow the provisions on the conformity of production to decide if these provisions could be directly inserted in the new Regulation on WLTP. The Chair of the IWG on Gaseous Fuelled Vehicles (GFV) mentioned that Annex 5 addressed specific additional requirements for GFV but he clarified that these requirements could also be included in the main annex on type 1 test.

37. GRPE endorsed the basic elements in GRPE-72-18 on the structure of both new Regulations (on WLTP and on other test types beyond type 1). GRPE noted the need to ensure a modular approach in the Regulation on WLTP with a general module on common provisions and specific modules adding further regional requirements.

38. Regarding the way forward on the transposition process, the expert from EC expressed his preference for setting up a Task Force reporting to the IWG on WLTP, rather than a new IWG reporting directly to GRPE. He underlined the relevance to have all Contracting Parties to the 1958 Agreement involved since the beginning to avoid the difficult integration of new elements at a later stage. The experts from Japan and India expressed their intention to participate in the Task Force.

39. GRPE endorsed the establishment of a new Task Force under the IWG on WLTP to deal with the transposition of GTR No. 15 into Regulations to be annexed to the 1958 Agreement. The Chair of GRPE invited Japan and the European Union to submit, as technical sponsors for these activities, an informal document to the March 2016 sessions of WP.29 and AC.3 to amend the proposed mandate for Phase 2 activities (ECE/TRANS/WP.29/2016/29) by including the established Task Force on the transposition process.

GRPE-72-18 | Transposition of GTR No. 15 WLTP into EU Regulations and UN/ECE Regulations

40. GRPE acknowledged the progress made by the IWG on WLTP and noted the request of the group for a meeting room for one day during the GRPE week in June 2016. GRPE welcomed the new leading team for Phase 2 activities and acknowledged the contributions of Mr. K. Kobayashi and Mr. K. Kolesa who, after Phase 1B, will no longer continue as Vice-Chair and co-Technical Secretary of the IWG on WLTP. The Chair of GRPE mentioned that the continuation of Mr. S. Redmann as Chair of the IWG on WLTP for Phase 2 activities still needed to be confirmed.

4. Heavy duty vehicles:
4. (a) Regulations Nos. 49 and 132

41. The expert from OICA presented ECE/TRANS/WP.29/GRPE/2016/6 to align the requirements on measurement equipment linearity verification in Regulation No. 49 with the provisions in Regulation No. 96. He clarified that the term “stand-alone” equipment was self-explanatory and it could be used in Regulation No. 49 without any additional definition.

42. GRPE adopted ECE/TRANS/WP.29/GRPE/2016/6 and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2016 sessions as draft Supplement 8 to the 05 series of amendments and draft Supplement 4 to the 06 series of amendments to Regulation No. 49.

54. The Chair of the IWG on PMP presented a status report (GRPE-72-22) on the activities of the group. He reported on the ongoing investigation on the measurement of exhaust particle emissions with a size below twenty-three nanometre and on the calibration of particle number measurement systems. He mentioned that the current PMP equipment specified in Regulation No. 83 could measure the number of particles with a size below twenty-three nanometre by properly changing the counting efficiency of the condensation particle counters, but he underlined the increased uncertainty of the measurements due to the presence of artefacts and particle losses, particularly when measuring particles of a size below ten nanometre. He explained that high dilution ratio helped reducing the artefacts but new technologies such as catalytic strippers would be recommended in this case. He continued his presentation on non-exhaust particle emissions as result of brake wear and the interaction between tyre and road. He explained that the good progress made on assessing particle emissions from brake systems may derive in a proposed test procedure in the future, whereas assessing tyre and road wear particle emissions was much more challenging. He added that it was likely to require more investigation due to the difficulty to separate tyre and road contribution.

55. GRPE noted the intention of the IWG on PMP to submit a summary report on the results of the investigation carried out on non-exhaust particle emissions at the next GRPE session in June 2016. GRPE acknowledged the progress made by the group.

8. Gaseous Fuelled Vehicles (GFV)

56. The Chair of the IWG on GFV introduced a status report (GRPE-72-24) on the activities of the group. He updated GRPE on the status of information exchange on GFV related issues in other forums such as the Working Parties on General Safety Provisions (GRSG) and on the Transport of Dangerous Goods (WP.15). He presented a new draft Regulation on the requirements for the type approval of retrofit systems intended to be installed on heavy duty diesel vehicles to enable its operation either in diesel mode or in dual-fuel mode (GRPE-72-12). He mentioned that some provisions were not yet finalized and that the scope of the original version of the Regulation would include Euro V and Enhanced Environmentally friendly Vehicles (EEV). He explained that, similarly to Regulation No. 115, there should be a split between provisions at the UNECE level on the engine retrofit system and additional requirements at the national level on the examination or inspection of the complete installation of the system in the vehicle. He pointed out the complexity to consider within the new Regulation the installation manual of the engine retrofit system due to very different types and applications within heavy duty vehicles.

57. GRPE noted the intention of the IWG on GFV to submit an official document on a new Regulation on the requirements for the type approval of retrofit systems for heavy duty diesel vehicles at the next GRPE session, based on GRPE-72-12. GRPE acknowledged the work progress made by the group and noted the request for a meeting room for half a day during the GRPE week in June 2016.

10. Electric Vehicles and the Environment (EVE)

64. The Chair of the IWG on EVE presented a status report (GRPE-72-23) on the ongoing activities on data and information gathering. He informed GRPE about the expected outcome under each of the areas corresponding to Part A of the mandate: (i) a report on the determination of energy consumption as a result of the activities led by China, (ii) a report on battery ageing and durability led by Canada and the United States of America likely to be recommended to be used for the development of a new annex to GTR No. 15 on WLTP, and (iii) recommendations on the development of a new annex to GTR No. 15 on the determination of the power of electric vehicles as result of the activities led by Germany and Korea. He underlined the agreement reached between the IWGs on WLTP and EVE to ensure a proper coordination of work avoiding any duplication and overlap on the area of battery durability. He informed GRPE that the IWG on WLTP would take the lead on the determination of requirements to be applied to aged batteries and other components, whereas the IWG on EVE would concentrate on the determination of ageing techniques.

65. The Chair of GRPE proposed to develop new GTRs instead of annexes to GTR No. 15. He suggested the IWG on EVE to exchange information with the IWG on Electric Vehicles Safety (EVS) under the Working Party on Passive Safety (GRSP) to harmonize battery ageing techniques for safety and environment purposes, if suitable. The expert from Japan volunteered to report on this matter to the IWG on EVS.

66. GRPE noted the intention of the IWG on EVE to submit the results of Part A on data and information gathering as a basis to discuss the way forward at the next GRPE session in June 2016.
