This October, as part of the Global Climate and Health Alliance’s #UnmaskMyCity initiative we teamed up with our members the Royal College of Physicians, the Royal College of Emergency Medicine and the Royal College of Psychiatrists, as well as Great Ormond Street Hospital and the Mayor of London’s Office, to highlight the comprehensive impacts of air pollution on our bodies, from our lungs to our mental health.

We produced a video in which the President of the RCP, “Bod”, cycles from the RCP offices in Regent’s Park to City Hall, whilst carrying a portable air quality sensor. He stopped along the way to speak to health professionals from a range of specialisms on how they see the impact of air pollution in their work – both through growing numbers of pollution related health conditions, and the strain that puts on the departments in which they work.

The video was originally shown at the Mayor of London’s International Air Quality Conference, and you can watch it below.

In a short blog, originally published by the BMJ, our Chair Richard Smith reflects on the cycling journey he helped to film, and discusses air pollution in London, how far we’ve come since the first Clean Air Act of 1956, how London compares to some rapidly developing cities, and what more we still need to do to protect the health of the public in London and across the UK.
