Lowest CO2 emissions - diesel cars
This is a list of the lowest emission diesel cars on sale, as new, in the UK today. Selecting a diesel 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 diesel emissions, while important, do not provide the whole picture for diesel 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 diesel 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 diesel model can reduce running costs by resulting in a lower car tax band and higher diesel MPG
