Summary of open issues, including items identified following the 12th WLTP informal group session, to be resolved towards finalizing the first phase development of the GTR on light vehicle emissions.

Draft informal document for eventual submission to the 72nd GRPE session (January 2016) containing final touches to the formal proposal (GRPE/2016/3) for the phase 1b amendments to the GTR on light vehicle emissions.

Consolidated proposal for the phase 1b amendments to GTR No. 15 including the changes presented in document WLTP-13-05 (marked up for easy reference).

Proposed Phase 2 organisation including structure for leading team and taskforces.

Project plan for the development of additional light-vehicle emissions test procedures for presentation to GRPE in January 2019. Phase 2 is expected to address test cycles (gear shift, normalization, and driving index), evaporative emissions, OBD, durability, and in-use compliance as well as supplemental tests for high altitude, severe cold, mobile air-conditioning, idling and crankcase emissions, and “eco-innovation”.

Proposal from Japan to clarify the specific objectives and intentions behind the list of supplemental test procedures developed for Phase 2 of GTR No. 15.

“Starter presentation” to launch discussions and work on evaporative emissions under Phase 2 of the GTR development.

Discussion paper concerning the transposition of GTR 15 into a UN Regulation. The paper raises two possible routes: 1) a UN Regulation identical to EU legislation but that would not be not applied (in its entirety as a distinct rule) outside the EU; 2) a “hierarchical” UN Regulation that combines all elements of all emissions thresholds at their most stringent level with lower levels of approval corresponding to regional/national requirements. The EC proposes option 2 as this would allow for a global rule where Contracting Parties could certify systems to standards outside their markets (e.g., Japan could issue approvals to EU standards and vice versa) under the UN Regulation.
