GEM Air Quality Ltd are independent air quality consultants, specialising in air quality assessments for planning and Environmental Impact Assessment (EIA) purposes. These may include scoping reports, screening assessments or detailed air quality impact assessments.

An air quality assessment would typically examine the impact of both the construction and operational phases of a particular development. Where there is a residential element to a particular development the air quality assessment would examine the impact of existing and future traffic emissions on the proposed development. Depending on the size of the proposed development (residential or otherwise) the air quality assessment may also require the impacts on the wider road network to be modelled, as an increase in traffic flows may result in a worsening of local air quality. 

The impacts associated with a particular development are compared against UK air quality objectives and/or significance criteria defined within relevant air quality guidance. Depending on the scale of these impacts the air quality assessment may also discuss the mitigation measures that will need to be adopted. Such measures will focus on the reduction of emissions during the construction phase, plus any measures relating to the introduction of new exposure into an area of existing poor air quality and/or the wider impacts of a proposed development on local air quality.

Following publication of the London Plan and the Mayor of London’s Sustainable Design and Control Supplementary Planning Guidance (SPG) we also undertake 'Air Quality Neutral' assessments, which are now required for all major new developments. These assessments focus on the building and transport emissions over a year and compare these with a benchmarked emission rate.

Established in early 2009, GEM Air Quality Ltd has established a wide customer base, including planners, architects and developers. Through its Managing Director, Grant Maly MSc BSc (Hons), GEM Air Quality Ltd has experience in undertaking numerous air quality assessments and monitoring projects. A selection of these projects can be found HERE.
