Review of the initial set of ADS Phase 2 work items and their integration into an ADS2 IWG plan for 2026-2028.
Terms of Reference establishing the IWG on A-LCA under GRPE to develop an internationally-harmonised procedure to determine the carbon footprint of different automotive technologies from production to use and disposal as a resolution under WP.29. Working items include defining scope, inventory analysis methodology, and A-LCA report format. The group’s mandate ends in December 2026 with possible adoption of the UN Resolution by WP.29 in November 2026. The IWG is open to all experts from any country or organisation of WP.29, chaired by Japan and Republic of Korea, with technical secretaries from OICA, E-Mobility Europe and Japan.
Overview of regional legislative and non-legislative activities related to vehicle life cycle assessment, including mandatory reporting requirements in Brazil from December 2026 and China battery carbon footprint reporting from 2027, voluntary reporting in the EU from June 2026, and ongoing methodology development in Korea, France, Japan, China, Spain, India, and the United Kingdom. The document reports on overarching activities including EU carbon border adjustment mechanisms, product environmental footprint recommendations, ISO and GHG Protocol standard updates, and customer information initiatives such as Green NCAP. Key message: the LCA landscape has moved from drafting to enforcement, with first reporting duties taking effect soon and individual regions establishing their own rules if harmonization does not continue.
This handbook provides testing and reporting procedures for the Third Inter-laboratory Study Phase 2, focusing on front brake testing for a Ford Puma vehicle per GTR No. 24. Testing comprises three emission cycles (Steps B and C with samples M1 and M2) followed by a fourth WLTP-Brake cycle (Step D) at 975 m³/h ± 10% airflow. Data must be reported using EBF, TBF, and MMF templates with specified formats and calculations. Post-test parts mass measurement occurs only after Step D completion. All values must be submitted as numerical values without formulae, with pre-test and post-test weighing procedures requiring buoyancy correction per GTR 24 specifications.
The A-LCA IWG decided not to submit a Working Document due to inability to reach agreement on outstanding issues. Activities are shifting to information and technical exchange rather than developing a Resolution until Contracting Parties are ready to share positions. The IWG has identified key contradictive issues including definitions of market-mediated effects and recycled content method, system boundaries for vehicle distribution stage, chain of custody, electricity modelling, use stage provisions, and replacement methodologies. New Terms of Reference are requested, reflecting the shift in focus and reduced meeting frequency.
Status report on the Informal Working Group on Environmental and Propulsion Performance Requirements for L-Category Vehicles. The IWG-EPPR has established a Task Force to transpose UN-GTR No. 2 into the 03 series of amendments to UN Regulation No. 40, co-chaired by Japan and Malaysia with JASIC and IMMA as co-secretaries. The Task Force held its first meeting on 9 October with participation from ASEAN countries, Ghana, and others, and agreed on workplan and rules of procedure. Target dates for deliverables are April 2027 and October 2027.
The first task force session confirmed the scope of work, organization structure, and timelines for developing UN R40.03 to transpose Euro 4-level requirements from UN GTR No. 2 into UN Regulation No. 40 and to ensure administrative provisions necessary for mutual recognition and type approval. The Task Force agreed to use IMMA proposal EPPR-73-02 as the technical baseline, identified provisions already aligned with GTR No. 2 and those requiring revision, and established a working method for future discussions. TF-02 is proposed for 24 November 2026 and will examine the main text from paragraph 1 through paragraph 12, including Appendix 2.
