Proposal for an amendment to UN Regulation No. 115
Download Document

Proposal to limit reporting requirements to the tested (or parent) vehicles in the type approval communication form by deleting the requirement to communicate CO2 emissions and power figures for each specific vehicle0. For vehicle types where the retrofit system is qualified (i.e. other than parent vehicles), the current model requires the communication of a calculated CO2 factor as well as of the specific CO2 emissions in natural gas mode. Since the specific CO2 emissions in gas mode are calculated by applying the CO2 factor to the emissions in petrol mode, communication of only the CO2 factor is sufficient to establish the CO2 emissions in gas mode of any vehicle type, when required.

4. GFV 40-02 has been proposed and discussed at the last GFV. The proposed amendment is aimed at simplifying the communication model of approval for LPG vehicles. As regards vehicle types for which the retrofit system is qualified (i.e. other than parent vehicles), the current model requires the communication of a calculated CO2 factor as well as of the specific CO2 emissions in the gas mode.

The proposal received approval from the GFV to move forward to the full GRPE meeting in June 2015.
