Two years after the Dieselgate scandal exposed the dirty nature of diesel cars, a new study (LINK TO STUDY) by Transport & Environment (T&E) shows that diesel cars not only pollute the air but also emit more climate-change emissions (CO2) than petrol cars. A lifecycle analysis of vehicle emissions proves that diesel cars over its lifetime emit 3.65 tonnes of CO2 more than a petrol equivalent. Diesel’s higher climate impact is due to a more energy-intensive refining of the diesel fuel; more materials required in the production of heavier and more complex engines; higher emissions from the biodiesel blended in the diesel fuel; and longer mileage because fuel is cheaper - see infographics below.
Transport & Environment (T&E) welcomes European Commission’s proposal today on smart road tolls and its commitment to zero-emission mobility. The Commission also reaffirmed its commitment to set stricter CO2 standards for cars, vans and, for the first time, trucks. These are moves in the right direction, but the real test of the EU’s intentions will be the ambition of the CO2 standards and whether it proposes a zero-emission vehicle mandate, the sustainable transport group said.
