What is the Clean Air Zone and how does it work? Why does Bradford need a Clean Air Zone? Frequently asked questions We have produced a map that provides information about levels of Nitrogen Dioxide (NO2) across the Bradford District. You can zoom in to your street and compare air quality data in 2018 with projected levels in 2022, after the Clean Air Zone is launched. To do this, click the Layers icon, switch on the relevant year, and refresh the screen. About the data: This data gives the annual average concentration of nitrogen dioxide at a location. This is because concentrations vary throughout the day, depending on traffic levels and weather conditions. The government measures nitrogen dioxide levels against a legal limit of 40 micrograms per metre cubed of air (40ug/m3), which is also an annual average figure. This data has been modelled at a height of 2 metres from the ground. As height and distance from the centre of the road increase, pollution levels fall due to dispersion. This data does not identify any localised short-term issues, e.g. a bonfire. There is an improvement in air quality across the entire area, including areas outside the Clean Air Zone, as ‘dirtier’ vehicles are discouraged from entering the zone and the proportion of ‘clean’ vehicles increases across the district. Data for 2022 includes traffic which is predicted to divert around the Clean Air Zone. If data for your street is not included, this is because it is outside the study area. The study area did not include areas where levels of air pollution are low and did not require modelling. This data has been examined in detail by independent government experts and has been found to be reliable.
