# Commission Implementing Decision (EU) 2016/160 of 5 February 2016 on the approval of the Toyota Motor Europe efficient exterior lighting using light emitting diodes 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), Division 4.2: Calculation of the CO2 savings

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

The total CO2 savings of the innovative technology (efficient exterior lighting system) are to be calculated by formulae (2), (3) and (4).
For a petrol-fuelled vehicle:
Formula(2):
C CO 2 = ∑ j = 1 m ΔP j × UF j × V Pe − P ∕ η A × CF P ∕ v For a diesel-fuelled vehicle:
Formula(3)
C CO 2 = ∑ j = 1 m ΔP j × UF j × V Pe − D ∕ η A × CF D ∕ v For a petrol-fuelled vehicle with turbo charger:
Formula(4)
C CO 2 = ∑ j = 1 m ΔP j × UF j × V Pe − PT ∕ η A × CF P ∕ v These formulae present the total CO2 savings of the innovative technology (efficient exterior lighting system) in gCO2/km.
The input data for the formulae (2), (3) and (4) are:
ΔPj Saved electrical power in W of the type of lighting j, which is the result of step 1
UFj Usage factor of the type of lighting j, specified in Table 2
m Number of types of lighting in the innovative technology package
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 l/kWh
VPe – D Consumption of effective power for diesel-fuelled vehicles, which is 0,22 l/kWh
VPe – PT Consumption of effective power for petrol-fuelled vehicles with turbo charger, which is 0,28 l/kWh
ηA Efficiency of the alternator, which is 0,67
CFP Conversion factor for petrol fuel, which is 2 330 gCO2/l
CFD Conversion factor for diesel fuel, which is 2 640 gCO2/l
