You might think you know how polluting your car is from official figures. On-road tests will be more accurate
Finding your car’s true pollution would have been nearly impossible as recently as a few months ago. But now you can discover the true emissions – harmful and otherwise – pumped out of its exhaust pipe. It’s courtesy of a company called Emissions Analytics which tests cars’ real-world performance for emissions and economy.
By measuring their miles per gallon and pollution output on the road, rather than in a lab like the official figures do, Emissions Analytics can build up a picture of how cars really perform. Just as you’ve probably found out for yourself that your car’s real-life economy differs from that claimed by its manufacturer, so its carbon dioxide (CO2) output is different too. Now, as well as your car’s true output of nitrogen oxide , you can find its real carbon dioxide output, as well as its genuine miles per gallon in every day motoring.
