Air quality management refers to the assessment, analysis and mitigation of air quality issues. CERC provides air quality management services to a diverse range of clients including city municipalities, local authorities, national government and agencies, the European Commission and developers and planners. Previous assessments have been carried out for locations as diverse as London, Singapore, Tbilisi and Cape Town. Our studies typically involve setting up an emission inventory (usually in consultation with the client), setting up air quality model(s), usually our in-house models ADMS 5 or ADMS-Urban, model verification and validation against available measured data, and then carrying out a series of model runs for both the current situation and future scenarios for various air quality management options. These frequently include source apportionment.
In the UK, the Local Air Quality Management (LAQM) process obliges all local authorities to review and assess air quality in their areas on a rolling three year cycle, and to determine whether or not the air quality objectives are likely to be achieved.
Where exceedences of the objectives are considered likely, the local authority must declare an Air Quality Management Area (AQMA) and prepare an Air Quality Action Plan (AQAP) setting out the measures it intends using to achieve the objectives.
CERC has been providing LAQM services to UK local authorities for over fifteen years and welcomes opportunities to assist with any aspect, from Updating and Screening Assessments or Progress Reports to air quality modelling for Detailed and Further Assessments and the compilation of emissions inventories. We closely follow the Review and Assessment Technical Guidance, making use of the available tools and Helpdesk services as necessary.
