Air quality and pollution

Emissions from industryWe undertook an EIA, air dispersion modelling and stack height determination for an extension to the Ras Abu Fontas power and desalination plant, Qatar

The successful implementation of air quality management policies and practices is one of the most effective means of protecting the environment, both in terms of community health and ecosystem integrity.


Delivering effective policy to improve air quality requires not only an in depth understanding of air pollution science but practical experience of the measures required to realise the benefits. These include land use and transportation planning, industrial pollution control and community partnerships.

Our work covers every aspect of air quality management from providing governments with technical advice on land use, transport, waste and environmental policies to assessing air quality as part of an environmental impact assessment or risk appraisal study for developers, financial institutions and government agencies.

As more and more governments seek to persuade people onto public transport, we are devising schemes such as congestion charging to encourage a model shift from the private motor car as well as designing public transport infrastructure including, for example, multiple transport nodes, fast track links to airports, bus lanes and light rail. In the industrial sector where the demands on operators to control emissions are ever more stringent, we are not only carrying out technical and engineering studies on industrial pollution control, but also designing, implementing and auditing environmental management systems for operational plants to comply with legislation and requirements of financial institutions.

Our specialist skills include:


  • Ambient air pollution monitoring
  • Stack emissions monitoring
  • Emission calculations and inventories
  • Stack height determination
  • Dispersion modelling, including point, linear and area sources,
    in isolation or in combination
  • Source apportionment
  • Air quality action plans and strategies
  • Legislative and policy review
  • Mesco-scale modelling.

Applications of our skills:


  • Environmental impact assessment
  • Environmental risk appraisal
  • Industrial abatement technologies
  • Land use planning
  • Traffic management
  • Policy development and interface.
Environmental impact assessments
Specific to air quality assessment and as part of environmental impact assessment studies or environmental management systems, we design and implement monitoring programmes to establish baseline air quality. Using a wide range of dispersion modelling techniques our experts assess the air quality impact of a specific project in terms of human health, ecosystems and vegetation as well as introducing abatement techniques as appropriate. To integrate air quality management within existing policy frameworks we develop emission inventories covering the transport, industrial, commercial and domestic sectors.
