What are the different types of vehicle emissions?

All petrol and diesel engines produce 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 is available in the types and impact section.

Electric cars are zero emission at the point of use, however emissions are produced during electricity generation, with the amount of emissions dependent on the type of power generation. Thus emissions from electric vehicles need to be considered on a lifecycle basis in order to include emissions from power stations. See how green are electric cars? for a high-level view on the impact of electric cars on climate change and air quality measures.

Next Green Car provides a unique lifecycle NGC Rating for all models which takes into account all emissions, not just tail-pipe CO2. This is more comprehensive than definitions of low emission cars which look at tail-pipe CO2 only. The UK government has recently defined an Ultra Low Emission Vehicle (ULEV) as one which emits 75g CO2/km or less. These vehicles qualify for a 100% discount on the London Congestion Charge.

Data in the search results above are updated weekly from the Next Green Car database.
