Emissions Analytics (www.emissionsnalytics.com), a company which tests emissions in real-world driving conditions and compiles data comparing its tests to laboratory tests, has announced that it will be launching an independent accreditation initiative on vehicle testing, in the wake of the illegal actions revealed by Volkswagan.
According to Emissions Analytics, consumers are "being mislead on emissions - with or without illegal acts". The company observes that:
"The illegal action of one manufacturer in the United States threw light, in dramatic fashion last week, on a European situation of higher than expected real-world emissions generated wholly or largely through legal activities. Even legal activity, where it gives rise to misleading results, can be enough to cast wrongful doubt on a whole industry. Having robust, independent real-world emissions data that can sort good from bad is the future, and we plan to lead this."
Since Emissions Analytics was established four years ago, it has tested over 1000 cars in Europe and the United States, including over 200 European diesel passenger cars. Its data, which is made commercially available to many parts of the automotive industry, shows that real-world emissions of the regulated nitrogen oxides are four times above the official level, determined in the laboratory. Real-world emissions of carbon dioxide are revealed to be almost one-third above that suggested by official figures. For car buyers, this means that fuel economy on average is one quarter worse than advertised.
Emissions Analytics points out that these differences may well be explained by limitations in the official system, rather than through illegality. The company has been highlighting these issues for some years now, as well as similar data from other sources. In order to make its findings more accessible and useable to the market, Emissions Analytics will now launch an independent accreditation initiative. All interested parties are invited to participate (more information at www.emissionsnalytics.com),
