Madrid Cures Air Pollution The Easy Way
When Alberto Ruiz-Gallardón, the mayor of Madrid, boasted of big reductions in air pollution since he had taken office in 2003, it seemed a moment for the city’s residents to celebrate an environmental breakthrough.
“Today we have better air quality in Madrid than ever before,” Mr Ruiz-Gallardón proclaimed.
Can London, Manchester and Birmingham follow the model?
The state prosecutor’s office found that in 2009 the Madrid municipality had quietly moved nearly half its pollution sensors from traffic-clogged streets in the city centre to parks and gardens.
If you do it the other way around, you can make places look hotter and more polluted.
