Green NCAP was launched in 2019 as a new, independent consumer organisation providing the most comprehensive assessment of new cars’ environmental impact. The star rating was based on two areas of assessment, with a score or ‘index’ for each: The Clean Air Index for how well a car limited its emissions of health-compromising pollutants; and the Energy Efficiency Index for how well the car converted raw energy into movement. It was the first time that a programme had attempted to provide such a balanced analysis of a car’s performance.
Those results are still available below and can be used to compare with other cars rated in the same year. However, Green NCAP’s 2020 rating scheme is more rigorous and broader, and 2019 ratings should not be compared to later ones.
