Draft letter intended for the UN Office of Legal Affairs to handle three planned series of amendments to the proposed UN Regulation transposing GTR 15 (WLTP) simultaneously. Normally, each series of amendments to a regulation must be implemented sequentially. In the case of WLTP, the informal group is proposing to use the series of amendment to implement stringency levels based upon regional needs (e.g., 00 series for the EU, the 01 series for Japan, and the 02 series as the most stringent set of requirements). The informal group is considering a request to handle this situation differently such that the 3 initial series would be implemented simultaneously, enabling future changes in regional stringency to proceed in a timely fashion (e.g., parallel development of new series based on regional objectives).

Document GRPE/2018/3 presents a consolidated revision of UN R96 to align the UN Regulation with Regulation (EU) 2016/162 concerning gaseous and particulate pollutant emission limits and type-approval for internal combustion engines for non-road mobile machinery. This proposal presents editorial improvements and corrects the provision allowing contracting parties to require in-service monitoring of engines by explicitly excluding its application from the scope of the Regulation.
