{{Use dmy dates|date=March 2019}}Green NCAP is a green vehicle assessment programme hosted and supported by the New Car Assessment Program in cooperation with European Governments.^[1] Organisation has test laboratories in 8 European countries and aims to increase awareness of the environmental impact of the vehicles. The first set of results was released on 28 February 2019.^[2]{{As of|2019|03}} organisation considers only energy used while driving, however it plans to expand testing procedures further, in order to cover entire life-cycle of the car as well as range of the electric vehicles.^[1]

Testing Procedure

Test is divided into two major stages. First one is a test on the chassis dynamometer, adhering to the WLTP procedure, with a slight modification: temperature is set to {{convert|14|C}}, which is close to European average, and the vehicle has lights, air conditioning and other typical systems turned on, while also carrying a realistic payload. In total an equivalents five WLTP tests are conducted.^[3]

The second part includes road testing with portable emissions measurement system which adheres to the further expanded European Union's Real Driving Emissions. Expanded testing conditions include driving at the altitudes from 0 to 1300 metres above sea level, and ambient temperatures from {{convert|-7|C}} to {{convert|35|C}}.^[3]

Scoring

Scoring is divided into Overall Rating - between 0 and 5 stars - and two major groups: Clean Air Index and Energy Efficiency Index.^[4]

Clean Air Index covers air pollutant emissions for Unburnt Hydrocarbons (HC), Carbon Monoxide (CO), Nitrogen Oxides (NO_x) and Particulates (PN) for each for the Laboratory Tests as well as the Road test.

Energy Efficiency Index covers energy efficiency of the entire vehicle, including aerodynamic drag, tyre friction or its mass. For even comparison with electric vehicles fuel consumption is converted into kWh using calorific value.

Green NCAP additionally tests greenhouse gas emissions, however they are not a part of the rating.
