Developers of environmental software including the well known Atmospheric Dispersion Modelling System, ADMS. The world leading ADMS-Urban calculates pollution concentrations at street level resolution over urban areas and links seamlessly to regional air quality models. ADMS 5 for industrial pollution combines state-of-the-art science with an unparalleled range of model features. Other models include FLOWSTAR, EMIT and customised products. Our consulting team use these and other models for a wide variety of environmental solutions.

About Cambridge Environmental Research Consultants

Cambridge Environmental Research Consultants was established in 1985 with the aim of making use of new developments in environmental research from Cambridge University and elsewhere for practical purposes.

The company is an SME (small and medium enterprise) with over 20 high level technical consultants. It has two technical directors at the forefront of their fields: Professor Julian Hunt, FRS, who acts as chairman, and Dr. David Carruthers, who is CERC's Managing and Technical Director. The Financial Director is Tim Newton. The company offices are located opposite King's College in the centre of Cambridge.

Environmental software

CERC has a world leading position in environmental software development and associated consultancy. This is achieved by encapsulating advanced scientific research into a number of user-friendly PC based models. The most well known of these is the Atmospheric Dispersion Modelling System (ADMS), of which there are now hundreds of licensed users worldwide. Other models include EMIT (atmospheric emissions), GASTAR for dense gas releases, LSMS for liquid spills and FLOWSTAR for flow over complex terrain with wind energy applications.

Developers of ADMS

The ADMS suite of models developed by CERC includes ADMS-Screen, ADMS 5, ADMS-Roads, ADMS-Urban and ADMS-Airport; these models cater for problems of different complexity. ADMS-Screen is used to assess the potential impact of a single point source, ADMS 5 for assessing impacts of industrial sites, ADMS-Roads for road traffic emissions and ADMS-Urban is an air quality modelling and management system for complex combinations of emissions in urban areas. ADMS-Airport has been used to model impacts of emissions at London Heathrow Airport for various proposed expansion schemes.

Consultancy services

CERC provides a range of consultancy services using both its own and third party models. These include assessment of the impact of industrial emissions, for example to support an IPPC application, and assessment of the impact of traffic emissions generated by a proposed development, for example as part of an Environmental Impact Assessment (EIA) for planning purposes. CERC has an active role in supporting Local Air Quality Management (LAQM) Review and Assessment work for local authorities, and extensive experience in emissions management and the compilation of emissions inventories of both toxic pollutants and greenhouse gases.

Environmental research

CERC undertakes research projects for Government Departments and Agencies and the European Union. Examples include the EuropeAid project Preparation of national emission reduction and ambient air quality assessment programmes, to assist Lithuania in developing a system for emission control and air quality management, the setting up of an air quality forecasting system in Beijing for the Olympic Games  and incorporating an amine chemistry model into ADMS for CCS applications.

Some of CERC's clients

  • well known companies, such as BP, Johnson Matthey, Savills, BAA, British Sugar, Mouchel, Dalkia, Jacobs;
  • UK government departments and agencies (Department for the Environment, Food and Rural Affairs (DEFRA), Department for Transport (DfT), Environment Agency, Food Standards Agency, Highways Agency);
  • local government (a significant proportion of UK local authorities use ADMS-Urban for air quality review and assessment);
  • international government departments, agencies and consultancies (e.g. European Union, Singapore National Environment Agency (NEA), ESA);
  • many universities and government institutes—research applications of CERC software and collaborative research.

Projects have been undertaken in numerous countries including many in Europe, China including Hong Kong, Malaysia, Thailand, India and the USA.


CERC - Version ADMS-Airport - Air Pollution Modelling Software

ADMS-Airport is a comprehensive modelling tool for air quality management of airports. It has many of the features of the ADMS-Urban model and includes allowance for all relevant emission sources at airports and utilises algorithms designed specifically to model dispersion from aircraft engines.

CERC - Version ADMS-Puff 1.4 - Advanced Software for Dispersion Modelling Dense & Passive Releases in Spatially Varying Meteorology

ADMS-Puff uses a Lagrangian puff methodology to model the fate of dense and passive gas releases. ADMS-Puff can use temporally and spatially varying meteorological data from the WRF model, or simple surface data. ADMS-Puff can also account for the impact of complex terrain: hills and variable surface roughness. ADMS-Puff calculates snapshots of instantaneous air concentration along with a time integrated dose. These concentrations can be compared ...


Accidental Releases and COMAH

CERC carries out a wide variety of assessments to look into the likely impact of accidental releases to air. These scenarios are often complex, requiring investigation of emission characteristics and the dispersion pathways under different meteorological conditions, as well as the use of CERC's models.

Carbon Capture and Storage Modelling Services

CERC is involved in the ‘CO2 capture Mongstad’ project, a major venture overseen by Statoil Petroleum AS and Gassnova SF (the Norwegian State enterprise for carbon capture and storage). Statoil and Gassnova are planning to equip the combined heat and power (CHP) plant at Mongstad refinery on the west coast of Norway with post-combustion carbon capture, potentially using amine technology.


Model FLOWSTAR - Airflow and Turbulence Calculator for Wind Energy

The model FLOWSTAR is designed to calculate the impact of complex terrain on mean airflow and turbulence at very high resolution, taking into account changes in both surface elevation and surface roughness.


CERC - ADMS-Urban Introductory Course

The aim of the ADMS-Urban training course is to introduce the ADMS-Urban software as a tool for assessing air quality across large areas, using worked examples to develop familiarity with main model input parameters and output, based on modelling small numbers of pollution sources.

CERC - EMIT Introductory Course

It is aimed primarily at anyone collating data on large numbers of sources releasing emissions to air, including the calculation of emissions. One example is local authorities involved in the review and assessment process. In brief, EMIT is an EMissions Inventory Tool, which can be used to store, manipulate and assess emissions data from a variety of sources. EMIT may be used to investigate the impact on emissions of various emission reduction ...
