Usual problem with these sort of tests, they are only measuring one type
of pollutant. Tends to lead to simplistic "cures" that only address part
of the problem.Â* It was the same concentration on one pollutant and
ignoring the others that gave us the Diesel Disaster.

To what are you referring when you use the phrase "diesel disaster"?

The obvious disaster is the losses incurred by those who followed
government advice and incentives by buying diesel cars rather than
petrol and are now being penalised for it?

It must be that.
