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).

Review of European testing to validate the Phase 1a test procedures of the light vehicle emissions GTR No. 15.

Status report to the WLTP informal group as part of the ongoing validation of the Phase 1a test procedures.

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.

Presentation from the WLTP informal group drafting coordinator on the status of the draft Phase 1b amendment to GTR No. 15 on light vehicle emissions.

Criteria for dual-axis chassis dynamometers have been added to the GTR in paragraph 2.3 in Annex 5, with the intention to make the use of a dual-axis chassis dynamometer mandatory for vehicles tested in 4WD mode. Though these criteria were put in place, there was no specific requirement added to include the requirement that vehicles tested in 4WD mode are actually tested on a dual-axis chassis dynamometer. This proposal would add a paragraph to address this omission.

Summary of feedback received from labs conducting tests according to the phase 1a version of the light vehicle emissions GTR No. 15.

Comments from India concerning the Phase 1b amendment to GTR No. 15 (document GRPE/2016/3).
