Sustainability Criteria

All biomass, biofuel, bioliquid or biomass fuel that is used to generate the CO₂ captured by the activity or as a feedstock for biochar production and any additional biomass, biofuel, bioliquid or biomass fuel consumed to produce energy for the activity must comply with one of the following sets of requirements, depending on the feedstock sourcing practices.

ID	Criteria	Documentation Required
SC1	Activities using forestry residues and downstream wood processing residues must comply with all the following criteria:
SC1.1	The feedstock must be sourced from an approved forestry certification or management program listed in Table A1 or from a region subject to an equivalent risk assessment.	The Operator must provide all of the following:- Evidence that the feedstock is sourced from an area or entity under a listed certification or management program, including evidence of the certification applicability and chain-of-custody. Where this cannot be evidenced, the Operator must provide an independent, third-party, risk based determination of low risk that a feedstock from the sourcing area is non-compliant with the principles equivalent to the FSC Forestry Management Principles and Criteria, in consultation with Isometric. Any additional documentation as required in Table A1.
SC1.2	Operators must demonstrate that woody biomass feedstocks - including both forestry residues and downstream wood processing (mill) residues - are sourced from areas of stable or increasing forest carbon stocks.	The Operator must provide one of the following:Evidence that the feedstock sourcing complies with the requirements in Article 29, paragraph 7 of Directive (EU) 2018/2001.

Where this assessment cannot be provided, the following may be considered with appropriate justification: Evidence that the average LULUCF of the state/country does not exceed the regeneration of the forest carbon stocks over the last 5 years. This is demonstrated if the net emissions are zero or under, as reported in the UNFCCC. In countries where the harvesting exceeds 5 million km², additional evidence that forest carbon stocks have not decreased over the previous 10 years is required.
SC1.3	Operators must demonstrate that woody biomass feedstocks, including both forestry residues and downstream wood processing (mill) residues, are not sourced from a primary forest.	The Operator must provide one of the following:Evidence that the feedstock sourcing complies with the requirements in Article 29, paragraph 6 of Directive (EU) 2018/2001.

3.0

Counterfactual Criteria

The counterfactual fate of feedstock to be used must be evidenced. The evidence of the counterfactual fate can take many forms including but not limited to:

Historical evidence of the counterfactual fate of the feedstock over the last 5 years provided by the feedstock supplier.

Regulatory enforcement that shifts the counterfactual fate.
An assessment of the expected fate over the last 5 years of the feedstock given the most economically viable option in a given sourcing area, including all data, documentation and assumptions used.
Retrofits can evidence the counterfactual as the pre-retrofit scenario (e.g., combustion with emissions released for bioenergy Activities).
In some cases, an affidavit from the feedstock supplier confirming the counterfactual fate of the feedstock may be considered.

All feedstocks eligible for crediting must meet one of the criteria listed in Table 2 to evaluate counterfactual storage.

Where $CO_2e_{Counterfactual} \gt 0$ :

$CO_2e_{Counterfactual}$ must be subtracted directly from $CR_{total}$ .

Table 2
Counterfactual Criteria
ID	Criteria	Documentation Required
Operatorss must demonstrate compliance with at least one of the following criteria for each feedstock. Notable examples where more than one must be satisfied include a BioCCS retrofit that can reference combustion for the consumption of feedstock for the underlying facility, but increases the demand for biomass to satisfy a parasitic energy requirement and therefore must reference a different counterfactual fate for this marginal biomass.
CC1	The $CO_2e_{Counterfactual}$ of the feedstock is quantified (See Section 3.3 of the Biomass Feedstock Accounting Module for details).	The Operator must provide a quantification of $CO_2e_{Counterfactual}$ including all documentation, data-sets, references and assumptions associated with the calculation of counterfactual storage.
CC2	Feedstock is sourced through a government managed, funded or otherwise supported wildfire mitigation program. The $CO_2e_{Counterfactual}$ of these feedstocks is 0.	The Operator must provide evidence that the feedstock originates from a government mandated, managed or otherwise supported wildfire mitigation program, including evidence of program participation and chain-of-custody.
CC3	The feedstock is rapidly oxidised or reduced such as in a high temperature environment in the counterfactual, such as an incinerator or open pit burn, resulting in negligible durable carbon storage in the counterfactual. This can include Operators that retrofit existing facilities that combust feedstock. The $CO_2e_{Counterfactual}$ of these feedstocks is 0.	The Operator must provide evidence of the feedstocks rapid oxidation/reduction in the counterfactual, such as disposal/end-use records, supplier affidavits or records of existing feedstock consumption at baseline facilities in the case of retrofits. In the case of retrofits/additive facilities, Operators must ensure that increased feedstock sourcing due to the Activity, such as to provide heat or electricity for the capture facility, is accounted for under another counterfactual criteria.

Equation 1 and equation 2 must be used to quantify the total CO₂e that is ineligible for Crediting.

 $CO_2e_{Counterfactual,\ x}\ \ = \ \ CO_2e_{Feedstock} \ \ - \ \ CO_2e_{CounterfactualEmissions}$

(Equation 1)

 $CO_2e_{CounterfactualEmissions} \ \ = \ \ min(CO_2e_{CounterfactualEmissions15}, \ \ CO_2e_{Feedstock}\ \ - \ \ CO_2e_{CounterfactualStorage50})$

(Equation 2)

Where:

$CO_2e_{Counterfactual,\ x}$ - The mass of biogenic carbon that is ineligible for crediting, in tonnes of CO₂e, for batch $x$ .
$CO_2e_{Feedstock}$ - The mass of biogenic carbon within the feedstock, in tonnes of CO₂e, for batch $x$ .
$CO_2e_{CounterfactualEmissions}$ - The mass of biogenic carbon eligible to count towards gross removals, in tonnes of CO₂e, for batch $x$ .
$CO_2e_{CounterfactualEmissions15}$ - The mass of CO₂e emissions that would be emitted from the feedstock in the counterfactual within 15 years, for batch $x$ .
$CO_2e_{CounterfactualStorage50}$ - The mass of biogenic carbon within the feedstock that would remained stored in the counterfactual after 50 years, in tonnes of CO₂e, for batch $x$ .

For each Certification Period, $CO_2e_{Counterfactual}$ must be aggregated across all feedstock batches, where $n$ is the total number of batches:

 $CO_2e_{Counterfactual}\ \ =\ \ \sum_{x=1}^{n}\ CO_2e_{Counterfactual,\ x}$

(Equation 3)

Where:

$CO_2e_{Counterfactual}$ - The total mass of biogenic carbon that is ineligible for crediting, in tonnes of CO₂e.
