This study estimates the long-term health impacts of exposure to air pollution in London from 2016 to 2050. The study finds that by 2050 policies in the London Environment Strategy (including the central London Ultra Low Emission Zone and expansion to the North and South circular roads) will result in:

  • almost 300,000 Londoners avoiding new diseases attributable to air pollution, such as coronary heart disease, lung cancer and dementia. This is a reduction of around one in every four air pollution related diseases
  • a cost saving to London’s NHS and social care system of around £5 billion
  • one million fewer air pollution related hospital admissions in London.

The maths is way over an intensivists head I'm afraid, but should appeal to some of you. However the ability to model cost to the NHS and morbidity down to borough level with and without intervention should be useful to explain the need for intervention in numbers that make sense. Sometimes smaller local numbers have more impact than saying 7 million people die each year from air pollution. The human mind is strange.
