Some diesel cars pollute less than petrols, study finds
The battle against diesel cars continues, with London's T-Charge in full force and several councils raising parking charges for diesel cars. But motoring groups are calling for a rethink after a study by Emissions Analytics found some diesel models actually emit less toxic nitrogen oxides than some petrol cars.
Emissions Analytics is a testing company that helped expose the health threat from diesels, but its latest findings raise questions about indiscriminate charges on diesel vehicles.
