Introduction to air pollution in Bristol

Dr Jo Barnes presented an introduction to air quality in Bristol at the Clean Air for Bristol event in July 2018. She covered the background information for the city, key statistics and conclusions for air quality in the city. This is a pdf version of the presentation. Among other useful resources and links, it includes:

  • A map showing the proportion of deaths attributable to air pollution (PM2.5 and NO2) in each ward in Bristol.
  • A map showing car ownership in each ward in Bristol
  • Overview of health impacts and sources of air pollution in Bristol.

Up-to-date air quality data

Did you know that hourly updates of Bristol’s air quality are available? This is collected and shared by the council.

Alongside the council’s data, the national Department for Environment, Food & Rural Affairs (DEFRA) also collect air pollution data in Bristol. They run a site in St Pauls and another near Temple Meads.

Council reports and plans

In February 2017 the council published a commissioned report on “Health Impacts of Air Pollution in Bristol.”

  • This report is the source of the “300 deaths per year” (or five per week) statistic.
  • The report includes maps showing attributable deaths per ward.

In June 2017 the council published a document on the Clean Air Action Plan and Clean Air Zone feasibility study for Bristol. The document is available in the minutes of the Council meeting (see p.78-145).

  • This includes the calculation that 40% of NOx in central Bristol is from diesel cars.
  • Information on the scope of the study as it was initially framed, and maps of the alternative Clean Air Zone proposals.
