21 Apr L-Vehicle Environmental and Propulsion Performance Requirements: Report of the 72nd (March 2026) session EPPR-72-03 2026-04-21 The 72nd EPPR session (March 2026) adopted the revised agenda and previous meeting report without changes. The 02 series of amendments to UN Regulation No. 40, transposing UN-GTR No. 2 to Euro 3 emission level (GRPE/2025/22 as amended by GRPE-93-26), was adopted for submission to WP.29/AC.1 in March 2026 and subsequently adopted by WP.29 at its 198th session. The IWG-EPPR Terms of Reference were extended for two years until 2027. IMMA offered to prepare a draft 03 series of amendments to UN Regulation No. 40 for Euro 4, tentatively expected by early June. The group agreed to reconvene around that time. The group reviewed information exchanges on maximum power determination, battery electric vehicle range determination standardization, and deterioration factors in GTR 23 on durability. Next meetings are scheduled for June, July, and September 2026, with the 76th session in October 2026 coinciding with GRPE.
30 Apr L-Vehicle Environmental and Propulsion Performance Requirements: Agenda for the 73rd (June 2026) session EPPR-73-01 2026-04-30 The agenda includes transposition of UN-GTR 2 into UN R40, with discussions on Euro 4 level amendments, maximum power determination for two-wheelers, battery electric vehicle range standardization using SAE J2982 procedures, and deterioration factors in GTR 23.
27 May UN R40: Draft proposal for a 03 series of amendments (IMMA) EPPR-73-02 2026-05-27 Proposal for a 03 series of amendments, modifying para. 5.4.1.4 (Table 5) to change emission limits for Classes 1, 2, and 3, amending para. 5.4.2.2 to establish CO measurement requirements at idle, adding para. 5.4.4.3 to establish requirements for O₂ content and lambda measurement at high idle with specified calculation methods, modifying para. 12 to change transitional provision references from 02 to 03 series, and inserting comprehensive new technical requirements throughout Annexes 1 through 7 and their Appendices 1 through 12 concerning vehicle propulsion unit families, test procedures for Type I, Type II and Type VII tests, exhaust dilution systems, driving cycles, gearshift procedures, reference fuels, chassis dynamometer specifications, and related emissions testing methodologies applicable to vehicles of category L<sub>3</sub>, L<sub>4</sub> and L<sub>5</sub>.

18 Jun L-Vehicle Environmental and Propulsion Performance Requirements: Report of the 73rd (June 2026) session EPPR-73-04 2026-06-18 The 73rd EPPR Informal Working Group Meeting on Environmental and Propulsion Performance Requirements of L-category vehicles was held 1 June 2026. The agenda and previous meeting report EPPR-72-03 were adopted without changes. The IWG discussed transposing UN-GTR No. 2 to Euro 3, 4, and 5 emission levels through incremental steps; the new 02 series of amendments to R40 was adopted by March 198/WP.29 (WP.29/2026/24), and IMMA presented a draft 03 series for Euro 4 level. The IWG agreed to identify legislative gaps via questionnaire due 26 June. Information was exchanged on maximum power determination, battery electric vehicle range determination standardization using SAE J2982, and deterioration factors in GTR 23 on durability. The next meetings are scheduled for 8 July 2026, 7 September 2026, and October 2026.
25 Jun L-Vehicle Environmental and Propulsion Performance Requirements: Agenda for the 74th (July 2026) session EPPR-74-01 2026-06-25 The agenda includes adoption of EPPR-74-01 and EPPR-73-04, transposition of UN-GTR 2 into UN-Regulation 40 across Euro 3, 4, and 5 emission levels using documents GRPE-93-07-Rev.1, GRPE-92-12, GRPE-92-13, GRPE/2025/22, GRPE-93-26, EPPR-73-02, and EPPR-73-03, maximum power determination discussions using EPPR-22-15 through EPPR-59-04, battery electric vehicle range determination standardization using EPPR-53-04 through EPPR-59-03, and deterioration factors in GTR 23 using EPPR-56-04 and EPPR-65-05. Next meetings are scheduled for 7 September 2026 and October 2026 in conjunction with 95/GRPE.
