How can different forms of electricity be included in GHG calculations?

If electricity is consumed from the grid, the emission factor of the regional electricity mix (EFelectricity) shall be used. In the case of the EU the most logical choice is the whole EU. If electricity from renewable energies is directly consumed (i.e. not supplied from the grid), an adapted EF for the type of renewable electricity may be used if that plant is not connected to the electricity grid. In the case that an electricity production plant is connected to the grid (e.g. a waste incineration plant), using the average emission value for electricity from that individual electricity production plant in the biofuel production process is permitted if it is guaranteed that there is a direct connection between the biofuel plant and the individual electricity production plant and that it is possible to validate the amount of electricity used with a suitable meter.
