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.
2019 is the year of introduction of Green NCAP’s assessments. The star rating represents the poorer performance in one of two areas: Clean Air and Energy Efficiency, each of which has its own index (score) out of a maximum of ten. The Energy Efficiency Index does not yet include assessments of the driving range or of driving resistance. 2019 assessments are comparable with each other.
