London Policy Guidance


The basic statutory framework is put in place for local air quality management by Part IV of the Environment Act 1995 (“the 1995 Act”, as amended, and “Part IV functions”) and national air quality regulations. This remains in place and is applicable to London’s 32 boroughs and the City of London (collectively referred to as “the boroughs”). However, it was agreed with the Department for the Environment Food and Rural Affairs in 2016 that the relevant local air quality management policy guidance for London should be different from that in the rest of the country in recognition of the particular challenges London faces. Defra have agreed that policy guidance for London should be issued by the Mayor, in recognition of his London-wide supervisory role. This reflects the Secretary of State’s own statutory guidance. As a result London boroughs need only refer to this document and to the accompanying LLAQM Technical Guidance as issued by the Mayor from time to time, rather than national guidance
issued by Defra.
