Are you wondering which car is the greenest? This will be evaluated in the future by the largest comparative test of "environmental greenness" Green NCAP, which is gaining in validity every year. Green NCAP is back for 2020 with a revised rating scheme and new results, which is a good indication of the direction Euro NCAP is heading. In addition to the already established and standard crash safety tests, this time the cars are evaluated on the basis of their sustainable environmental acceptability.
