The purpose of this proposal is to include the necessary transitional provisions to Supplement 4 to the 01 series of amendments to Regulation No. 101, in order to ensure consistency between the reference fuels prescribed in Regulation No. 83 (Emissions of M1 and N1 vehicles) and those prescribed in this Regulation.

Proposal to align UN Regulation No. 101 with the latest changes in the regulatory framework of the European Union in relation to the specifications of new reference fuels E10 and B7. Adopted by the Working Party on Pollution and Energy (GRPE) at its 68th session based on document GRPE/2014/5, not amended.

Proposal to align the regulation with the full requirements for vehicles that meet “special social needs” under the regulatory framework of the European Union. In response to the extension of the scope of Euro VI legislation down to 2380 kg vehicles, this proposal would also add an exemption to take into account overlap between UN R83 and UN R101 with regard to light-duty vehicle CO₂ emissions and fuel/energy consumption. This proposal was adopted by the Working Party on Pollution and Energy (GRPE) at its 68th session based on document GRPE/2014/3, as amended by para. 25. of the session report and document GRPE/2014/7, not amended.
