WP.29 Rulemaking Project
Light Vehicle Emissions Type Approval Test Procedure

This page covers the work on transposing GTR No. 15 (Worldwide Harmonized Light Vehicle Emissions Test Procedure-WLTP) into the form of a UN type-approval regulation as used under the 1958 Agreement.

Pushed by the European Union as part of the effort to improve emissions regulations, Japan also signed on in May 2015 to develop the text (see document GRPE-71-02 for more details).
