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.

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.
