An ‘air quality’ campaign is being launched urging businesses clean up their act and help reduce pollution in the City triggered by a smog incident before Easter.

Air quality in parts of the Square Mile and surrounding districts such as Aldgate and Whitechapel are said to be the worst in the country and among the worst in Europe.

“Poor air quality has a significant impact on people’s health, especially children,” said Dr Lesley Mountford, Public Health director of NHS East London & The City.

“The poor air quality in the City and neighbouring areas before Easter should remind us that pollution is still a real problem.”

Emissions from taxis and delivery vehicles added to emissions from buildings are believed responsible for much of the pollution.

So firms are being asked to take steps to reduce emissions linked to deliveries or with heating and cooling systems.
