# Commission Implementing Decision of 18 November 2014 on the approval of the battery charging Webasto solar roof 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) (2014/806/EU), Division 4: In order to demonstrate that the minimum threshold of 1 g CO2/km is exceeded in a statistically significant way the following Formula (9) is to be used:

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

Formula (9):
MT ≤ C CO 2 − Δ C CO 2 –
Where:
MT Minimum threshold (g CO2/km), i.e. 1 g CO2/km;
CCO 2 Total CO2 saving (g CO2/km);
Δ C CO 2 – Error of the total CO2 saving (g CO2/km)
Where the CO2 emission savings, as a result of the calculation using Formula (9), are below the threshold specified in Article 9(1) of Implementing Regulation (EU) No 725/2011, the second subparagraph of Article 11(2) of that Regulation shall apply.
