# Commission Implementing Decision of 10 March 2014 on the approval of the light emitting diodes low beam module ‘E-Light’ as an innovative technology for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance) (2014/128/EU), Division 4.2: Calculate the CO2 savings

Extent: E+W+S+N.I.

The formulae to calculate the CO2 savings of the eco-innovation are:
For a petrol-fuelled vehicle:
Formula (2) C CO 2 = ΔP × UF × V Pe-P ∕ ηΑ × CF P ∕ v
For a diesel-fuelled vehicle:
Formula (3) C CO 2 = ΔP × UF × V Pe-D ∕ ηΑ × CF D ∕ v
Where in these formulae CO2 is the CO2 savings in g CO2/km.
The input data for the formulae (2) and (3) are:
ΔP Saved electrical power in W, which is the result of step 1
UF Usage factor which is 0,33 for a low beam lamp
v mean driving speed of the NEDC, which is 33,58 km/h
VPe-P consumption of effective power for petrol-fuelled vehicles, which is 0,264 1/kWh
VPe-D consumption of effective power for diesel-fuelled vehicles, which is 0,22 1/kWh
ηΑ efficiency of the alternator, which is 0,67
CFP conversion factor for petrol fuel, which is 2 330 g CO2/l
CFD conversion factor for diesel fuel, which is 2 640 g CO2/l
