Background of the scheme
Following the government release of the UK Plan to tackle roadside nitrogen dioxide levels, Derby was identified as one of five authorities (outside London) required to implement an action plan to improve air quality. Alongside Birmingham, Leeds, Nottingham and Southampton, Derby was included in this ‘first wave’ because national modelling suggested locations existed on the city’s transport network where nitrogen oxide concentrations would exceed prescribed limits by 2020, if no action was taken. These prescribed limits were determined by EU legislation in 2008 and have subsequently been adopted into UK legislation.
A ministerial direction, issued by government in December 2017, required the Council to deliver a plan that would ensure any predicted exceedances in nitrogen oxide concentrations are addressed in the shortest possible time.
