The WLTP was adopted by the Inland Transport Committee of the United Nations Economic Commission for Europe (UNECE) as Addenda No. 15 to the Global Registry (Global Technical Regulations) defined by the 1998 Agreement.

It aims to replace the previous and regional New European Driving Cycle (NEDC) as the new European vehicle homologation procedure. Its final version was released in 2015. One of the main goals of the WLTP is to better match the laboratory estimates of fuel consumption and emissions with the measures of an on-road driving condition. Since CO2 targets are becoming...
