1. WP 5: GHG emission reduction (&) certification Stefan Majer, Maik Budzinski
BIOSURF Kick-off, Palais Liechtenstein, Vienna,

2. Introduction to WP 5
In the recent years, the demonstration of GHG mitigation effects from the production and use of biofuels has gained significance importance
The EU RED 2009/28/EC has set mandatory GHG-mitigation thresholds for the use of biomethane as a transportation fuel and includes a methodology for the calculation as well as a number of default values:
Biogas* from municipal organic waste 73%
Biogas* from wet manure 81%
Biogas* from dry manure 82%
Default values for Biomethane are limited to wastes and residues, no values available for biomethane from energy crops
The application of the RED methodology for biomethane provides some challenges and open questions

3. Main Objectives of WP5
Development of guidelines on calculating entitlement to CO2-certificates for the biomethane
Definition and assessment of a number of exemplary biomass-to-biomethane- value-chains with regards to their environmental impacts.
Based on these assessments:
a number of recommendations for the adaptation of the RED GHG calculation methodology can be developed and
the most prominent drivers for emissions in the analysed biomethane pathways can be identified and described.

4. Methodology (acc. to EU RED)
Main Objectives of WP5
Data
Methodology (acc. to EU RED)
potential methane emission reduction due to processing of:
allocation of by-products,
organic waste,
credits for avoided emissions,
agricultural by-products (incl. manure),
emission factors,
methane leakage,
etc.
substitution of mineral fertiliser,
discussion of best available data and highlighting further need for research
recommendations for the adaptation of the RED GHG calculation methodology

5. Activities and Tasks

6. Activities and Tasks Task 5
Activities and Tasks Task 5.1 Lead: AKB participants: EBA, FNR, HBA, DBFZ, GBA
Methane emission reduction due to processing agri by-products
Analysis of emission reduction potential due avoided methane emissions caused by storage and application of untreated farm fertilizer and on methane emission caused by depositing animal by-products on landfills as well as C and N2O losses through catch crops and straw rotting process.

7. Activities and Tasks Task 5
Activities and Tasks Task 5.2 Lead: REA participants: DBFZ, EBA, GBA, FNR
Methane emission reduction due to processing organic waste
Analysis of emission reduction potential from the use of organic waste in biogas units and thus avoided landfill site deposition.

8. Activities and Tasks Task 5
Activities and Tasks Task 5.3 Lead: AKB participants: DBFZ, FNR, GBA, EBA
GHG emission saving due to replacement of chemical fertilisers
Detailed analysis of the GHG emission reduction potential achievable by applying the fermentation residue as organic fertiliser replacing industrial chemical fertilisers.

9. Activities and Tasks Task 5
Activities and Tasks Task 5.4 Lead: DBFZ participants: AKB, FNR, EBA, REA
GHG emissions caused by biomethane production (Life Cycle Analysis)
Definition specific exemplary process chains (based on the information and results provided by tasks and WP 4) and assessment of their GHG-emissions and their GHG mitigation potential.
Exemplary process chains will reflect country specific substrate compositions, supply scenarios as well as scenarios for the use of the digestate.
As a result of these tasks a number of recommendations for the adaptation of the RED methodology to calculate GHG emissions will be given.

10. Activities and Tasks Task 5.5 Lead: DBFZ participants: EBA, AKB, REA
Methodology for entitlement to CO2 certificates
The results of the work carried out in Tasks 5.1 – 5.4 will be integrated into Guidelines on calculating entitlement to C02 certificates by biomethane producers.

11. Activities and Tasks Deliverables in WP 5
D5.1: Recommendations for the adaptation of the GHG calculation methodology for biomethane systems included in Annex V of the EU RED (Month 18);
D5.2: Assessment of GHG reduction potentials due to the use of animal excrements and organic waste streams as biogas substrates and the replacement of industrial chemical fertilisers by digestate (Month 20);
D5.3: Methodology for the calculation and certification of GHG emission caused by the production of biomethane (in the whole Life Cycle) (Month 22);
D5.4: Description of the most prominent drivers of emissions in LCA for biomethane production (Month 24);
D5.5: Comprehensive Methodology on calculating entitlement to CO2 certificates by biomethane producers (Month 30).

12. Time schedule and next steps
First proposal to discuss the exemplary process chains for the LCA in Task 5.4
Discuss main input parameters for LCA to be provided by Tasks
Begin Literature review on upstream emissions from synthetic fertiliser production
