All children in London face illegal pollution levels, as air quality limits were exceeded in all boroughs in the capital.
Outside London, Yorkshire was worst-affected, with an estimated 83 percent of youngsters in the region living with illegal pollution levels. In July, ministers unveiled court-mandated plans for meeting EU limits on nitrogen dioxide, much of which comes from road transport and particularly diesel vehicles.
But official estimates suggest compliance for nitrogen-dioxide levels will not be met until 2026.
Air pollution causes an estimated 40,000 premature deaths a year and is linked to problems including heart disease.
Labour’s environment spokesman Sue Hayman said: “With the majority of our young people now growing up in areas that breach air quality limits it’s clear the UK is in the middle of a dirty air emergency. Dirty air is a clear and present health hazard; it can take years off a person’s life.
“We need to act, to protect the health of all our children and the wellbeing of the country.’
A spokesman for the Department for Environment, Food and Rural Affairs said: “Air pollution has improved significantly since 2010, but we recognize there is more to do which is why we have put in place a £3.5 billion plan to improve air quality and reduce harmful emissions.
“We will also end the sale of conventional new diesel and petrol cars and vans by 2040.”
