Air Quality Assessments

An Air Quality Assessment, or an AQA as they are more commonly known as, can often be required by the local planning authority. The impact of air quality is pervasive, with ample scientific evidence highlighting its significant health benefits, particularly on individuals' respiratory and cardiovascular health. Recognising this, legislative measures have been implemented, including the Environmental Act 1990, Air Quality Standards Regulations 2010, and the 2023 Regulations, regarding Fine Particulate Matter. These Acts have begun shaping both national and local planning policies. Consequently, local authorities frequently seek air quality assessments to inform planning decisions and environmental permit applications. These assessments encompass three distinct types, each building upon the other. They begin with Baseline Air Quality Assessments, progress to Standard Air Quality Dispersion Assessments, and culminate in Air Quality Impact (Sensitive Receptor) Assessments. Assessments include Dust Assessments for the construction sector, while developments within London also incorporate Air Quality Neutral Assessments.)

An Air Quality Assessment is often required regarding a proposed development that may be affected by existing air pollution or when the proposed development could result in an impact on local air quality.  This could have a potential negative impact on the environment and the people.

A professional air quality assessment report helps assess the potential effects of the proposal on nearby receptors and the surrounding environment. This is particularly important for sites close to main roads, junctions, commercial premises, or other sources of traffic emissions, dust, and poor air quality.

A typical air quality assessment reviews existing local air quality conditions, nearby sources of traffic-related air pollution, potential impacts on future occupants and neighbours, construction dust and site activity, sensitive receptors such as homes, schools, and public spaces and, if necessary, details mitigation measures.
