# Commission Implementing Decision (EU) 2016/1721 of 26 September 2016 on the approval of the Toyota efficient exterior lighting using light emitting diodes for the use in non-externally chargeable hybrid electrified vehicles 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: Formula 5

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

S k CO 2 – = S k CO 2 T = ∑ t = 1 T k CO 2 t − k CO 2 – 2 T T − 1 where:
T Number of measurements performed by the manufacturer for the extrapolation of the k CO 2 as defined in Regulation UN/ECE No 101, Annex 8
k CO 2 – mean of the T values of k CO 2 t
The standard deviation of the power consumption of each efficient exterior LED light ( S P EI i – ) and the standard deviation of the k CO 2 S k CO 2 – lead to an error in the CO2 savings ( S C CO 2 ). This error is to be calculated by means of Formula 6.
