Greenhouse
Gas Emissions Inventories |
|
|
CERC has been commissioned by Cambridgeshire County Council to produce an inventory of greenhouse gases emitted from within the county. This covers the emissions of carbon dioxide, methane and the other gases for which national targets were set by the 1997 Kyoto Protocol. Cambridgeshire's Environmental Strategy includes policies and targets for the reduction of these emissions and this study forms a key part of this, in particular the development of future policies. CERC are using the EMIT software package, developed for use with all types of atmospheric emissions data, to process all of the emissions from within the county. This includes data obtained on traffic emissions, industrial and rail transport emissions together with emissions from urban areas and agricultural activities. The principal of our work for the county is to generate greenhouse gas emissions from activity data, strongly linked to geographic information. For example, traffic emissions are calculated from traffic flows on a road by road basis, and industrial emissions according to their site. Domestic and generalised commercial emissions figures are calculated from land-use patterns. This "bottom-up" approach means that the inventory is less data specialised, and can use commercially available (or free) "off the shelf" datasets to generate the inventory. It is not necessary to have gas, electricity or other consumption data - which has been an historic barrier to such projects. At the end of the
project, because the data is in EMIT format, it will be suitable for
future reference and management by the council, making it a dynamic source
of information for years to come. |
