Commission Report Com(2010)11
The Commission Report COM(2010)11 on sustainability requirements for the use of solid and gaseous biomass sources in electricity, heating and cooling was published on 25 February 2010 and gives GHG emission savings of some 30 solid and gaseous biomass production pathways. It also states a formula for economic operators to perform own calculations: Total GHG emissions are the sum of emissions from cultivation, processing and transportation of the biomass.
Yet the report neither gives any methodological background nor specifies standard values to convert production inputs into emissions – e.g. the emissions typically caused by a cargo ship per tonne and kilometre.
