Text of the proposed new GTR on light vehicle emissions and fuel consumption as approved at the November special session of the Working Party on Pollution and Energy and submitted to the Forum for consideration and adoption at its March 2014 session.

Report to accompany the proposal for the new GTR on light vehicle emissions and fuel consumption detailing its development.

Proposal for a further “phase 1b” in the development of the GTR on light vehicle emissions. In order to meet Contracting Party objectives, the draft GTR has been submitted for adoption by the Forum in March 2014. Although the current draft offers a complete test cycle, the WLTP experts want to improve the regulation by further addressing a number of technical elements that were set aside due to time and resource constraints.

Swiss study on heavy duty vehicles with NOx reduction systems (SCR or DPF+SCR systems) towards defining a simplified test procedure for measuring emissions, including prospects for applying such testing to retrofit emissions control systems.

Notification of the first meeting to work on refinements to the GTR on light vehicle emissions that will likely be voted on at the World Forum session next March. This new phase of work (“phase 1b”) expects to produce an amendment to the GTR that will address technical elements set aside in the interests of meeting participant deadlines for establishing the basic test cycles.

Agenda for the meeting to launch “Phase 1b” for the further development of the proposed GTR on light vehicle emissions.

Presentation prepared by the WLTP secretary for discussion at the 5th informal working group session.

Amendment proposal to add test procedures for heavy-duty hybrid vehicles to the global technical regulation on eavy-duty road vehicle emissions (WHDC).

Report of the expert group (WLTP-DHC informal group) on their development of the driving test cycle for the Global Technical Regulation on light-duty vehicle emissions and fuel consumption (World Harmonized Light-duty vehicle Test Procedures).
