Air Quality Neutral Assessment for the Greater London Plan

Air Quality Neutral Assessment

Contact: airquality@arcusconsulting.co.uk

There is a requirement in the Greater London Plan for ‘major’ developments (10 or more residential dwellings, or an area greater than 0.5 hectares) to be air quality neutral, with further guidance provided in the Sustainable Design and Construction Supplementary Planning Guidance (SPG) and the Air Quality Neutral Planning Support Update. The aim of the policy is to avoid baseline “creep” due to the cumulative impact of more than one development on local air quality.

The requirements are to:

  • Determine the relevant NO2 and PM10 building emission benchmark for the development, based on its land use class and location;
  • Calculate the NO2 and PM10 emissions from the development’s buildings and compare these with the benchmark;
  • Determine the relevant NO2 and PM10 emission benchmark for transport; and
  • Calculate the NO2 and PM10 emissions from transport and compare these with the transport benchmark.

Building and transport emission benchmarks should be met in order to achieve air quality neutral requirements. Our consultants can undertake these assessments for major developments in London. Please contact airquality@arcusconsulting.co.uk for more information, or to request a quotation.
