The BioGrace GHG calculation tool allows the reproduction of the calculation of the Annex V default values of the Renewable Energy Directive (2009/28/EC) (RED) for biofuel production pathways as well as to perform individually adapted calculations. The calculations use the BioGrace list of standard values and follow the methodology laid down in the RED, as well as more specified calculation instructions by communications and decisions of the European Commission.

The calculation rules apply for adapted calculations in the BioGrace tool, when calculating new pathways, new processes or for new inputs in the tool. The calculation rules form integral part of this calculation tool: when using the tool the calculation rules must be respected.

In general, the BioGrace GHG calculation rules are in line with the standard that is being prepared under CEN TC 383 “Sustainably produced biomass for energy use” – Working Group 2 “Calculation for the GHG emission balance, fossil fuel balance and respective calculations, using a life cycle approach”. As this standard will not be published before end of 2011, no reference was made to the CEN TC383 draft standard on GHG calculation in this document.
