Testing results on GBEP methodological framework
When GBEP GHG Task Force started in Oct. 2007
in Germany a GHG methodology for biomass
had been just under development for legal purpose.
In 2008 the European Commission enhanced
the methodology dispute.
Output:
basic calculation rules have been constituted within
the Renewable Energy Sources Directive by late 08.
Adopted by the German legislation in 2009.
Introductory Remark
Testing results on GBEP methodological framework
What I want to tell you:
1. We applied the GBEP framework to the
German method
- which is based on the EU rules.
2. We compared some exemplary calculation using
different methods and applied the logic of the
GBEP framework for analyzing the differences.
Introductory Remark
Testing results on GBEP methodological framework
The “German method”
As determined within the:Ordinance on requirements pertaining to sustainable production of bioliquids for electricity production (Biomass-electricity-sustainability ordinance)

an analogous one is prepared for biofuel for transport

Testing the “German method”
Step 1: GHGs Covered
German Sustainability Ordinance (adopted from EU RED)
IFEU meth. previously proposed for Regulation
CO2 Yes (1) Yes (1)
CH4 Yes (23) Yes differentiation made betw. fossil: (21)and non-fossil CH4 (18.25)
(values acc. to Kyoto-Prot.)
N2O Yes (296) Yes (310)(value acc. to Kyoto-Prot.)
HFCsConsidered to be negligiblePFCs
SF6
othersRemark: meanwhile IPCC 2007 factors should be applied

Step 2: Source of biomass
German Sustainability Ordinance (adopted from EU RED)
Please explain definition of waste:
Substance that the holder intended to discard
Substance that had zero or negative economic value
Substance for which the use was uncertain
Substance that was not deliberately produced and not ready for use without further processing
Substance that could have adversely affected the environment
No definition just a general that certain feedstock of less “value” like agricultural crop residues (straw, husks, nut shells and even bagasse and non refined glycerine) will enter/leave the system boundary with zero emission.

Step 3: Land use change
German Sustainability Ordinance (adopted from EU RED)
Direct land use changes are taken into account
Yes
Indirect land use changes are taken into account
Not yet!
(in line with a European amendment the German regulation will adopt this)
A combination of both is included Yes (bonus for production on previously degraded land will subtracted from dLUC value.

Step 4: Biomass feedstock production
German Sustain. Ordinance (adopted from EU RED)
1. Sources of direct GHG emissions and removals are accounted for:
YES
Emissions from operating farm/forestry machinery YES
Emissions from energy used in irrigation YES
Emissions from energy used in transport of feedstocks
NO (this is included in step 5)
Emissions from energy used to prepare feedstocks YES
CO2 emissions from lime/dolomite applications YES
N2O emissions resulting from the application of nitrogen fertilizers:
YES
_direct; __volatilization; __runoff/leaching YES (model by JRC)

Step 7: By-products and co-products
German Sustain. Ordinance (adopted from EU RED)
1. By/Co-products from the biomass are accounted for.
YES
2. By/Co-products from non-biomass feedstocks are accounted for.
YES
3. Explain definition of by/co-products No specific definition
4. An allocation method is used (Y or N): YES
Allocation by energy content YES
Method to determine energy content: Lower heating value (of dry matter or fresh substance ?)

Step 10: Comparison with replaced fuel German Sust. Ordinance (adopted from EU RED)
….8. Emissions from extraction/production are accounted for (Y or N)
Yes
8a. Direct and embodied emissions in extraction/production accounted for:
___ Fuel combustion from drilling Yes (but unclear)
___ Fugitive methane emissions from equipment Yes (but unclear)
___ Fuel combustion from turbines and compressors
Yes (but unclear)
___ Transportation emissions from helicopters and supply vessels
Yes (but unclear)

Comparing exemplary calculations
We compared some exemplary calculation using
different methods and used the GBEP framework
for analyzing the differences.
Exemplary case: sugar cane ethanol (Brazil)
Models:
RTFO (U.K. Calculator by DfT)
EU Default values
IFEU model
CA-GREET (California for LCFS)

Conclusion
The GBEP methodological framework is an
outstanding tool to get a detailed portrait and
profound characterization of any GHG method
for bioenergy.
Completed templates may appear to provide an
overflow of information. However such piles of
information are extremely wanted when GHG
balances are considered increasingly in decision
making.
