The Golden State plans to eliminate petroleum diesel by 2030 and replace it with renewable diesel. This would eliminate 71% per cent of greenhouse gas diesel emissions and not only combat climate change but also improve the air quality for millions. Paris has taken a different approach and plans to ban diesel cars from the city by 2024. Because petrol cars emit more Co2 this will lead, at least initially, to worse effects for climate change. The plan also entails that on the long run only electric and hydrogen-fueled cars are allowed.
California’s plan seems more feasible because renewable diesel can be used now, without the need of technological adaptations or advances. Especially as from this infographic it is obvious that from a CO2 emissions point of view is not wise to ban the diesel-engine entirely! Here you can read all about it.
