Policies to encourage a shift from motorised transport to walking and cycling are needed to improve London's air quality, Public Health England have said.
Figures showed that 3,389 deaths in the capital in 2010 have been linked to pollution levels.
Dr Paul Cosford, PHE's director of health protection and medical director, said:
Policies that encourage a shift from motorised transport to walking and cycling would be expected to reduce total vehicle emissions, including particulate pollution.
If this could be achieved in towns and cities, then we could expect local improvements in air quality. There would also be health benefits from increased physical activity through walking and cycling.
Over 3,000 deaths In London have been linked to poor air quality, new figures have revealed, as health authorities called for more to be done to tackle the issue.
Around 3,389 deaths were attributed to pollution in 2010, Public Health England (PHE) said.
'Very high' levels of pollution in the capital last week renewed calls for more to be done to improve air quality.
The highest number of deaths were recorded in the south east of England where 4,034 deaths in people over the age of 25 were linked to air pollution.
