Real-world NOx emissions revealed by new website

Written by Ellie

A new website will soon be launched to encourage motorists to buy vehicles with better real-world emissions.

The Cleaner Vehicle Checker will outline how much toxic nitrous oxide (NOx) is emitted by new cars, in a bid to push motorists towards more environmentally-friendly vehicles and incentivise manufacturers to market less polluting cars.

While carbon dioxide (CO2) emissions are more widely publicised due to their impact on vehicle excise duty and company car tax, NOx emissions receive significantly less exposure but have been proven to be more damaging to the environment and public health. Even then, the output figures can vastly differ when the vehicles are driven on actual roads.

Due to go live from autumn 2017, the website will use data from Emissions Analytics to offer independent evaluations of the emissions of most new cars and vans available in the UK.

It is hoped that manufacturers will feel pressured to produce vehicles that conform to the EU’s full ‘real-world driving emissions’ standards sooner than the 2021 legal deadline.

Another desired aim is that London fleet operators will understand how their current fleet performs and where significant improvements could be made.

The tool will be used by the Greater London Authority Group and local authorities to select appropriate vehicles for their fleets.

London mayor Sadiq Khan believes the website will end ‘the smoke and mirrors’ approach employed in official emissions tests and provide motorists with an accurate and independent evaluation of vehicle emissions, helping them make an informed choice.

“This scheme is also a fantastic example of how big cities around the world can pool their expertise and their influence to encourage big industry to clean up its act,” he commented.

“The toxicity of the air in London and many other big cities is an outrage, and schemes of the type have the potential to make a massive difference to the quality of the air we all breathe.”

Natalie Brinkley, brand manager at Fuel Card Services, adds: “We’ve seen some car makers take it upon themselves to publish real-world fuel consumption figures and the availability of even more accurate data can only be a good thing.”
