Car emissions

Vehicle emissions are a major contributor of greenhouse gases leading to climate change and local air pollution affecting human health. As a result, many tax signals and incentives in the UK are now directly linked to vehicle emissions and fuel type. Examples include car tax, company car tax and the 100% discount on the London Congestion Charge.

Next Green Car's microsite provides an overview of the key vehicle emissions, an explanation of the NGC Rating and a selection of search tools to help you find a low emission car. These tools enable searches by CO2 emissions, by make and model and to calculate car emissions by vehicle and distance.

The microsite also includes an introduction to Ultra low Emission Vehicles (ULEVs) which are defined as cars and vans with tailpipe CO2 emissions of 75 g/km or less.
