Someone shared this, its half-interesting: Theres this anual "Sustainable Motorsport Index" released every year and ERC continues to be high on the ranking, only behind FormulaE, ExtremeE, F1, MotoGP and the extinct eWTCC. I know that "Not traveling around the world" counts A LOT, but its interesting to see. WRC is 15° on the list, behind crazy poluted stuff like the European Truck Series and Nascar.... Guess the hybrid engines are not doing much for them?
