Emissions inventories and emissions vertification/optimisation

CERC are expert in calculating, managing and manipulating emissions data from a wide spectrum of sources, including road traffic, shipping, aircraft, power stations, industrial processes and domestic and commercial heating, often using our EMIT software package.

We compile many emissions inventories across a wide range of scales, from single road junctions through to comprehensive databases for towns, cities and large urban areas such as Cambridge, Tbilisi, Singapore and Kuala Lumpur.

We are also experts in manipulating existing emissions inventories, such as the London Atmospheric Emissions Inventory (LAEI) and UK National Atmospheric Emissions Inventory (NAEI). For the calculation of air quality pollutant emissions, we use the most up-to-date, detailed emission factors. For example, in order to allow for the uncertainty relating to published diesel NOx emission factors, CERC has taken steps to improve on published emission factors using real world emissions data.

For the estimation of greenhouse gas emissions, we use methods and emission factors laid out by the Intergovernmental Panel on Climate Change (IPCC).

Where emissions are uncertain, we can apply our own advanced inverse dispersion modelling techniques together with ambient concentration measurements to verify and optimise emissions of both toxic pollutants and greenhouse gases.

Whether the focus is on toxic pollutants or greenhouse gases, emissions from relevant activities are calculated and stored in EMIT, for ongoing analysis of the emissions themselves and/or for dispersion modelling.
