Version history
Remove biogas torching parameter
Below impact threshold
May 2023
V1.1
Define gas self consumption rate of 4%
GHG results not sensitive, simplify data collection
May 2023
V1.1
Set digestate produced to 85% of the sum of feedstock input fresh mass
Precise values rarely available
May 2023
V1.1
Add possibility to have digestate separated during storage, and during spreading
Improved accuracy
June 2023
V1.1
Specify amounts and nutrient content of different phases of digestate (raw, liquid, solid)
Improved accuracy
June 2023
V1.1
Remove transport of manure and slurry in baseline and project scenario
Assumed to be the same in both scenarios, no effect in a comparative LCA
June 2023
V1.1
Add options for digestate transport via irrigation pipes or truck transport
Improved accuracy, more relevant options for Project Developers
June 2023
V1.1
Calculate digestate storage methane emission rate based on residence time in digester, rather than fixed rate of 2% of biogas produced
Improved accuracy
July 2023
V2.1
Updated parameter on amount of methane leaked during purification
Error in units conversion
September 2023
V2.2
Add possibility for projects to provide their own data on methane leakage rates during purification, instead of standard leakage rate of 0.7% of biogas leaked
Improved accuracy, increased use of project specific data
October 2023
V2.2
New section Monitoring Plan
Alignment with Standard Rules V6
March 2024
V2.3
Add share of biogas in the grid to the baseline scenario
Alignment with Riverse Standard Rules V6 and increase conservativeness.
March 2024
V2.3
Added equations for calculation GHG reductions
Increased transparency.
May 2024
V3.0
Aligned terminology with ISO 14064-2:2019
Improved consistency with the voluntary carbon market. LCA principles still apply.
May 2024
V3.0
Added risk assessment template for environmental and social do no harm
Provide more detailed and prescriptive assessment framework, clearer instructions for project developers.
May 2024
V3.0
Removed text for sections that are the same for all methodologies:
Measurability
Real
Additionality
Technology readiness level
Minimum impact
Independently verified
Repeated text from the Standard Rules.
May 2024
V3.0
Added Monitoring Plan section
Alignment with Riverse Standard Rules V6.
May 2024
V3.0
Remove Rebound Effect and Independently Validated criteria
Alignment with Riverse Standard Rules V6.
May 2024
V3.0
Added uncertainty assessment section
Alignment with Riverse Standard Rules V6.
May 2024
V3.0
Model infrastructure instead of full data collection, move under “Digestion and biomethane management” section
Simplification, results not sensitive to impacts
May 2024
V3.0
Model activated carbon based on energy production, instead of direct data collection
Simplification, results not sensitive to impacts
May 2024
V3.0
Change biomethane combustion methane emissions from fossil to biogenic
Error
May 2024
V3.0
Reintroduce transport of manure and slurry in baseline scenario
Completeness, often collected project transport distance anyway
May 2024
V3.0
Add five different energy cover crop options, instead of a single proxy
Improved accuracy, increased use of project specific data
May 2024
V3.0
New Leakage requirements
More rigorous eligibility criteria, and clear requirements and instructions for Project Developers (after public consultation)
July 2024
V3.0
Include methane emissions from manure and slurry storage in project and baseline scenarios
Public consultation feedback, erroneously assumed previously that they are the same in project and baseline scenarios
July 2024
V3.0
Create project scope requirements
Specify the project scope as one anaerobic digestion site
October 2024
V3.1
Add minimum list of ESDNH risks
Align with Standard Rules V6.2
October 2024
V3.1
