The European Commission's DG ENER develops and carries out the Commission's policies on energy.

The overall objective of this project is to provide information about the lifecycle GHG emissions of fossil fuels used in transport based on collection of actual data to the extent possible. The considerable information uncertainty related to the collection and elaboration of these data, as well as to the required regional/geographical specification of data has been tackled with the assessment of the range of the GHG emissions in the form of minimum, maximum and weighted average values.

The natural gas supply network for Europe is much more complex than it is in North America. GHGenius was used to model 27 different NG supply chains in Europe. The modelling used publicly available data from member states published energy balances and information from their UNFCCC National Inventory reports.
