This page was last updated on 7th January 2021Climate Change is recognised as one of the greatest environmental threats facing the World today and it has long been appreciated by governments that reducing the impact of the motor vehicle has an important part to play in addressing this threat.
We have developed databases listing most of the cars and new vans available for sale in the UK.

WLTP replaced the NEDC test procedure for establishing the official Fuel Consumption and CO2 emissions of new cars in September 2017, which became mandatory for all new cars (powered by an Internal Combustion Engine) by September 2018.
This guide lists the fuel consumption, CO2, and other tail pipe emissions performance figures of new cars currently on the market in the UK
Dealers are obliged to present a label showing the official fuel consumption and CO2 data for every new car displayed in a showroom or as part of an exhibition
Information about the collection and processing of average emissions data
We have developed databases listing most of the cars and new vans.
If your business is involved in the supply of new cars in the UK, you must provide certain information under the Passenger Car (Fuel Consumption and CO2 Emissions Information) Regulations 2001, and the amendment Regulations 2004,2013 and 2018.

Information is provided by manufacturers on a voluntary basis and subject to checks before being published on the New Car Fuel Consumption and Emissions database.
In the UK, road transport is now the largest source of CO2 emissions.
Emissions of the main air pollutants are regulated by the EU Euro emissions standards, under the vehicle ‘type approval’ process.
