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. It was the same concentration on one pollutant and
ignoring the others that gave us the Diesel Disaster.

True, though particulates seem to be one of the main causes of urban
ill-health. That's now a much bigger factor than global warming, at least
as far as local regulations are concerned.
