Defra asked AEA to estimate the CO2 equivalent factor of wood pellets and chips, in kg CO2 eq/MWh, including emissions from transport and processing of the wood, and emissions associated with combustion. AEA were also asked to estimate the NOx and black carbon emissions associated with transport, processing and combustion, and consider whether these indirect greenhouse gases could be included in the overall CO2 equivalent factor. In order to do this, a modified version of the Biomass Environmental Assessment Tool (BEAT2) was used.
