Specific CNG (Compressed Natural Gas) Retrofit Systems to be Installed in Motor Vehicles for the Use of CNG in their propulsion system 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. 1 May 2015
