| Agenda and orientation slides for the 32nd A-LCA Material and Material Recycling (SG2) session |
| Reference Number: A-LCA-SG2-32-01 |
|
The A-LCA IWG will not submit a Mutual Resolution for adoption at the October 2026 GRPE session; instead, a status report will be presented to GRPE. Work towards completion of the methodology should continue and a revision of the Terms of Reference will be prepared. After the 95th GRPE session in October, an Information/Technical Exchange phase will start with continuation of technical meetings at reduced frequency and organisation of dedicated technical sessions only when required. Due to scaling back of A-LCA’s activities, SG2 activities will be suspended from October. |

| Framing the Tyre Abrasion task force brainstorming session of October 2026 |
| Reference Number: TA-51-05 |
|
A two-day brainstorming session will be held in Brussels during October 8-9, 2026. The session aims to address the lack of a concrete test method solution for C3 tyre abrasion by reflecting on innovative test method ideas not bound to existing C1 and C2 approaches, brainstorming phased introduction of tyre abrasion requirements across C3 tyre segments, and optimising resources to reduce testing burden. Day 1 will address C3 market complexities and tyre segmentation across duty cycles; Day 2 will cover methodological ideation, funding and resource allocation, and review of the C2 test campaign before the February 2027 working document. |

| Draft Tyre Abrasion task force status report |
| Reference Number: TA-51-04 |
|
The Task Force on Tyre Abrasion completed work on the UN Regulation on tyre abrasion for C1 tyres and is launching C2 work. UN R186 on tyre abrasion for C1 tyres was adopted at WP.29’s 199th session in June 2026, with a two-stage implementation approach beginning 30 June 2028. C2 test method development is ongoing with an Informal Document to be submitted to GRBP in February 2027 instead of September 2026. C3 tyres will undergo a brainstorming session in October 2026 before commencing testing. |
