Revealed: nearly all new diesel cars exceed official pollution limits

Ninety-seven percent of all modern diesel cars emit more toxic nitrogen oxide (NOx) pollution on the road than the official limit, according to the most comprehensive set of data yet published, with a quarter producing at least six times more than the limit.

Surprisingly, the tiny number of models that did not exceed the standard were mostly Volkswagens, the carmaker whose cheating of diesel emissions tests which emerged last year sparked the scandal. Experts said the new results show that clean diesel cars can be made but that virtually all manufacturers have failed to do so.

The new data, from testing industry leader Emissions Analytics (EA), follows the publication this week by the Department for Transport of emissions results for 37 vehicles, all of which emitted more NOx on the road than the official limit. But the new data covers more than 250 vehicles in more stringently standardised road conditions. EA found that just one of 201 Euro 5 diesels, the EU standard from 2009, did not exceed the limit, while only seven of 62 Euro 6 diesels, the stricter standard since 2014, did so.

Diesel cars must meet an official EU limit for NOx but are only tested in a laboratory under fixed conditions. All vehicles sold pass this regulation but, when taken out on to real roads, almost all emit far more pollution. There is no suggestion that any of the cars tested broke the law on emissions limits or used any cheat devices.

3. Mr. Chairman I have to two test results that you wanted

One are the actual results and the other are the results you wanted

(The Chairman takes the results he wanted) and says, "Diesel be fine. "





Thank you for taking that trip with me. I know it started slower than a diesel at a red light.
