Lowest CO2 emissions - petrol cars
This is a list of the lowest emission petrol cars on sale, as new, in the UK today. Selecting a petrol car with low emissions will have less impact on the environment and also result in reduced car running costs - fuel costs, car tax and company car tax levels are all related to CO2 emissions.
Tail-pipe petrol emissions, while important, do not provide the whole picture for petrol emissions and can be misleading when viewed in isolation. The Next Green Car Rating, a unique lifecycle rating system looks at all emissions across the life of the vehicle, and enables comparison across fuel types and model types.

What are the types and impact of emissions from petrol cars?
Petrol and diesel cars emit harmful exhaust emissions including carbon dioxide (CO2), carbon monoxide (CO), particulate matter (PM) and nitrogen oxides (NOx). These emissions not only contribute to the increasing concentration of greenhouse gases leading to climate change and but also have an impact on air quality. Road transport also remains the main source of many local emissions and air pollution, more info available in the types and impact section.
Choosing a low emission petrol model can reduce running costs by resulting in a lower car tax band and higher petrol MPG
