The steady decline in sales of diesel vehicles in the UK may have attributed to the average carbon dioxide emissions from new cars actually rising by 0.8% in 2017. , 300px wide Electric cars vs petrol cars. This does not mean that petrol is better than diesel from an environmental point of view however. Diesel engines are more efficient than gas engines. The study also shows that diesel cars emit significantly higher levels of other air pollutants, especially nitrogen oxides (NOx) and particulates. Daft.ie, Are diesel cars really better for the environment than petrol ones? are better than petrol cars taking into acc ount the underlying uncertainties and assumptions about their environmental effects. Please see our privacy policy for more details. Diesel cars do more miles to the litre than petrol, but this exaggerates the difference in CO 2 emissions since one litre of diesel contains more energy and more carbon than one litre of petrol. In 2014, the ratio had almost exactly switched to 26 per cent versus 74 per cent. Minister Anne Rabbitte: 'The voice at the end of the line told me to back down or they'd come for me'. Emissions and environment: Petrol engines generally emit more CO2 than diesel engines, but they’re better on other harmful emissions, such as nitrogen oxides. Of course, two of diesel fuel's environmental advantages have always been that diesel engines get better mileage than traditional gasoline engines and diesel fuel requires less refining. These are a compromise for many, as they are better suited for longer journeys than pure electric cars. So, although they’re not emission-free, they are considerably better than a carbon-creating petrol or diesel car. The Fuel. So electric cars are quicker than petrol/diesel cars.
