Air Quality Assessments

Air Quality Assessments, often referred to as AQA may be required by the planning authority. The impact of air quality is pervasive, with ample evidence highlighting its significant health ramifications, particularly on respiratory and cardiovascular health. Recognising this, legislative measures have been implemented, 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. Additionally, all assessments include Construction Phase Dust Assessments, while developments within London also incorporate Air Quality Neutral Assessments.)

An Air Quality Assessment is often required where a proposed development may be affected by existing air pollution or could create impacts on local air quality.

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.
