Emissions inventories and emissions vertification/optimisation

CERC has expertise in calculating, managing and manipulating emissions data from a wide spectrum of sources, including shipping, industrial processes, road traffic, aircraft, power stations and domestic and commercial heating.

We have compiled emissions inventories across a range of scales, from the proposed redesign of a single road junction to the compilation of a comprehensive database for urban areas, such as Cambridge, Tbilisi and Singapore.

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 highly uncertain, we can apply 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 using the EMIT software package, for ongoing analysis or dispersion modelling.
