Air Quality Assessments



What is an Air Quality Assessment?

Air Quality Assessments are vital in the planning phase of a project to support air quality mitigation and meet Environmental Impact Assessment (EIA) targets. Stroma Built Environment’s Air Quality Consultants can deliver specialist services for both residential and large scale commercial developments. DEFRA quotes more than 500 individual Air Quality Management Areas in the UK in approximately 250 local authorities – our specialist consultants can help you determine air quality risks at an early stage in your development.






Air Quality Assessment services – Why choose Stroma Built Environment?

Stroma Built Environment will provide a thorough Air Quality Assessment to support clients with planning applications. Our expert Air Quality Consultants will communicate and liaise with local authorities throughout the process. Your dedicated assessment examines environmental impacts during the construction and operation of a development.

Our Air Quality Assessment services can include:


A desktop review of air quality using existing monitoring and/or modelling data

Monitoring of air quality at the site to provide baseline data

Air dispersion modelling in accordance with Defra guidance LAQM.TG(16) and as agreed with the local authority

Monitoring of air quality during construction and/or operations


An indication of the number of receptors that will be exposed to poor or improved air quality as a result of the development

An outline and justification of mitigation measures associated with the design, location and operation of the development. This includes consideration of orientation, elevation of residences, low emission travel plans and the use of green infrastructure such as green walls, screens and trees

An assessment of the impact on air quality during the construction phase and detailed mitigation methods for controlling dust and pollution emissions associated with plant and vehicles

We follow air quality guidance criteria and assess against UK air quality objectives to provide a client report following the assessment, for direct upload to the Planning Portal. If the environmental impacts are significant we can also recommend measures to mitigate them and produce Mitigation Statements. These consider reductions to emissions, exposure risks in areas of poor air quality and the local air quality around the development.

Dust Management Plan

Government guidance states that an emissions management plan for dust may be requested by the Environment Agency if you are performing specific operations within 2km of an air quality management area or within 500m of a home, school, hospital or nursing home. Stroma can help you create a Dust Management Plan for the storage, treatment, disposal or recovery of any materials specified by the Environment Agency.

Low Emissions Statement

A Stroma Low Emissions Statement can help you to assess and monetise the local emissions from a development in order to determine the appropriate level of mitigation required to help reduce the potential effect on the local environment and/or health.

Air Quality Dust Risk Assessment

The construction phase can result in the following air quality impacts; elevated PM10and PM2.5 concentrations, increased concentrations of NO2, visible dust plumes and dust deposition. A Stroma Air Quality Dust Risk Assessment will evaluate the risk of these impacts on local receptors and provide recommended mitigation measures for the Construction Environmental Management Plan.

Air Quality Planning Guidance

Local authorities are required to determine the impact of air quality on developments during the planning phase of all projects. The National Planning Policy Framework (NPPF) states that the presence of Air Quality Management Areas is a key requirement (see also the London Councils Air Quality and Planning Guidance).

The legislation suggests that in areas of poor air quality a development may impact on the air quality of the surrounding area. Under these circumstances an air quality assessment should be included as part of the planning application. The air quality assessment can sometimes be considered during post planning as a reserved matter. Where the development also includes a biomass boiler, CHP plant and/or a large car park, many local authorities will also stipulate the requirement for an air quality assessment.

The London Plan

"Air Quality Neutral" assessments can also be provided in line with the requirements of the London Plan for major new developments in London (Following publication of the London Plan and the Mayor of London’s Sustainable Design and Control Supplementary Planning Guidance (SPG)). These compare building and transport emissions over a year with a benchmarked emission rate.

Stroma Built Environment offers a range of consultancy services to help clients comply with the Zero Carbon requirements of the London Plan. Our Energy Statements and Sustainability Statements are delivered by our team of energy consultants for the development of an energy strategy to meet the London Plan targets.
