Environmental Impact

The operation of aircraft has an environmental impact relating to noise, emissions and air quality. We have technical and advisory roles in these areas and can use our expertise to influence the policy debate. We are experts in aircraft noise and emissions, leading the development of new international emission certification standards for aircraft CO2 and particulate matter.

Noise Contouring

The UK Civil Aviation Authority (UK CAA) has developed the Civil Aircraft Noise Contour Model (ANCON), which calculates the contours from data describing aircraft movements, routes, noise generation and sound propagation. Using this powerful data modelling tool, we can assist Governments and operators to calculate noise exposure contours, forecast the noise impact of new Airports or existing Airport developments and to forecast the impact of changes to Air Traffic Operations.


We can also provide advice on the latest research and requirements for compliance with regulatory guidelines set by the International Civil Aviation Organisation (ICAO) regarding emissions limits from aircraft engine exhaust. We have the expertise to estimate the differences in CO2 emissions and fuel burn resulting from a change in flight procedures. This type of analysis can, for example, be used for the environmental assessment of an airspace change.
