Sustainable Biomass Program links greenhouse gas calculation to existing chain data
The Sustainable Biomass Program (SBP) has launched a calculation tool that allows companies with an SBP certificate to calculate and report their greenhouse gas emissions in the biomass chain. The GHG Calculator retrieves its data from the Data Transfer System, the system in which SBP records information about certified biomass throughout the chain. Through this connection, the certification body aims to reduce the number of manual steps and minimize the risk of input errors.
Measurability plays an increasingly important role in the biomass debate. In addition to the origin of the raw material, it also concerns emissions during production, processing, transport, and use. For companies that purchase or trade wood pellets, wood chips, or other solid biomass, it is becoming increasingly important to record emissions at each link in the chain.
Less manual labor in the supply chain
According to SBP, the calculator retrieves the necessary data directly from the Data Transfer System. Because that system is already used for the exchange of supply chain information, companies need to manually enter fewer figures. This reduces the risk of errors and, according to SBP, limits the need for specialized calculation knowledge.
The tool is built in accordance with SBP Instruction Document 6D, the European Renewable Energy Directive (RED III), and the Japanese SBP instruction document. In this way, it aligns with regulations in the markets where certified biomass is used for energy production and where requirements regarding sustainability and greenhouse gas reduction apply.
Users can choose between default values and actual company data. This reveals the difference between a calculation based on general assumptions and a calculation using proprietary figures. Additionally, the tool can compare default values from the European RED and the Japanese system of feed-in tariffs and feed-in premiums against results based on measured data, and in some cases, compare market- and location-specific emission factors for electricity.
From raw material to end user
The calculator was primarily developed for end-users of biomass, such as energy companies or industrial parties that need to report on their use. However, SBP also sees value earlier in the chain. Producers can estimate the CO2 footprint of their product, traders can weigh the impact of transport choices, and certifying bodies can use the data during audits.
That broader use aligns with the nature of the emissions. Emissions do not originate in a single location but are linked to the origin of the raw material, the energy required for processing, the distance to the end user, and the mode of transport. The picture can shift at each step, and the choice between actual data and default values also influences the outcome.
Independent assessment by SGS
SBP reports that the calculator has undergone an independent limited assurance review by SGS, an internationally operating testing and certification company. During this review, the methodology and operation of the tool were assessed, and no material issues were identified.
That assessment says something about the design, not about each individual calculation. The outcome remains dependent on the quality of the entered data and the way companies record their processes. However, the structure of the tool has been externally reviewed. In a sector where figures on climate gains are closely monitored, that counts.
Relevance for the Netherlands
This development is important for the Netherlands because biomass occupies a controversial but still present place in the energy supply and the broader biobased economy. Policymakers, businesses, and civil society organizations want verifiable data regarding origin, sustainability, and climate impact.
A calculation tool like this does not settle that debate, but it can help verify claims. When supply chain parties use the same methodology, emission figures can be compared with one another. It then becomes easier to distinguish biomass streams with a low climate impact from chains in which production or transport weighs heavily.
Meanwhile, societal demand extends beyond greenhouse gases alone. Sustainable biomass also impacts biodiversity, land use, soil quality, and competition with other applications of wood and residues. The calculator focuses on climate reporting. However, other criteria remain necessary for a comprehensive assessment of sustainability.
Data are becoming more decisive for trust
The launch aligns with a shift in the biomass sector, in which certification is moving from paper declarations to digital chain information and calculations that comply with regulations. SBP itself calls the tool a step towards more accessible and consistent greenhouse gas reporting.
For companies, this can yield practical benefits: less manual processing means a lower risk of errors and potentially lower administrative burdens. For regulators and customers, comparability is what matters most. As the data becomes more accurate, it becomes clearer where in the chain the most emissions originate and where there is room for improvement.
The calculation tool therefore does not provide a judgment on biomass, but rather figures that allow buyers and regulators to verify a claim. Whether those figures also lead to lower emissions in the chain depends on the choices companies make afterwards.
