RSB's GHG calculator developed by Roundtable on Sustainable Biomaterials (RSB), It is an indispensable tool for the accounting of greenhouse gas emissions (GEE). Essential in the transition to a low carbon economy, The calculator stands out for the rigor and transparency, supporting organizations that operate with biomass, biofuels and other sustainable products in accordance with international standards.

What is RSB and its GHG calculator?
A RSB It is a non -profit global organization that promotes sustainability in the biomass and bioenergy sectors through internationally recognized certification standards. Yours GHG calculator It is an advanced technical spreadsheet, Excel -based, designed to calculate GEE emissions throughout the entire life cycle of sustainable products, from agricultural production to the final use stage (if applicable).
This tool is used by companies certified by RSB, Auditors and Consultants, to ensure that products meet the criteria of Environmental and Climate Sustainability required for certification and legal conformity.
Standards and Methodologies that RSB GHG Calculator meets
The RSB calculator was developed based on principles of technical rigor and international harmonization, And it is compatible with:
- European Directive of Renewable Energy - RED II / (EU) 2018/2001
The calculator reflects the life cycle analysis methodology required by the European Union, especially with regard to the calculation of energy emissions and the maximum limits allowed for sustainable products. - GHG Protocol – Corporate Standard & Product Life Cycle Standard
Although GHG Protocol has a wider scope (covering any type of company or product), The Accounting Principles (as materiality, consistency and completeness) are reflected in the RSB calculator. It is particularly compatible with the approach to scope 1, 2 e 3, Focusing on emissions per functional unit. - ISCC I E ISCC PLUS
The calculator also fulfills the criteria of International Sustainability and Carbon Certification, especially for European and global markets. O ISCC, Just like RSB, requires the calculation methodology to be transparent, verifiable and technically consistent with RED II. - ISO 14040/14044 (Life Cycle Evaluation)
Although the RSB spreadsheet is not a complete LCA software tool, It adopts the fundamental principles of A.C.V., especially regarding allocation, definition of system borders and functional unit.
Comparative between RSB, GHG Protocol and ISCC
Criterion | RSB GHG Calculator | GHG Protocol | ISCC Calculator |
Main focus | Sustainable biomass and bioenergy | Corporate and various products | farming, Biomass and Energy |
Regulatory base | RED II, ISO 14040/44, GHG Protocol | WRI/WBCSD, ISO 14064 | RED II, ISO 14040/44 |
Tool type | Parametrized Excel spreadsheet | Guides and frameworks | Integrated spreadsheet and software |
Usability | Average (requires technical knowledge) | Alta (customizable, but generic) | Average (sectoral) |
Audit and Verification | RSB certification with 3rd part | Voluntary or regulatory | ISCC certification with 3rd part |
Detail level | Alto (Focus on traceability) | Medium to (depends on the application) | Alto (for the agricultural and industrial sector) |
GHG Protocol
- Similarities:
- Scope accounting 1, 2 e 3
- Focus on emissions transparency
- Differences:
- RSB more specific for biomaterials
- More rigorous sustainability criteria
ISCC (International Sustainability & Carbon Certification)
- Convergence points:
- Productive chain traceability
- Sustainability Criteria
- RSB distinctive elements:
- Greater emphasis on social aspects
- More comprehensive calculation methodology
RSB calculator differentials
- Specificity of the sector - The calculator is designed for specific contexts of biomass, waste, Biofuels and Biochemicals, What makes it more accurate for this niche than generic tools.
- Facilitated Audit - Its standardized models and the traceability of the entries facilitate the audit and the certification process.
- Modularity and Transparency - Each stage of the life cycle is represented separately, allowing point to point analysis.
- OWN EMISSION FACOR - It is possible to use RED II default factors or enter primary data verified, giving technical flexibility.

Conclusion
The RSB GHG calculator consolidates as a reliable tool and aligned with the main international carbon emissions accounting standards. For companies that want to work with climate responsibility and enter regulated markets, It offers methodological security, transparency and traceability, at the same time as it allows comparability with widely recognized methodologies, Like GHG Protocol and ISCC.
Be for certification purposes, REPORT REGULATORY OR POSITION, the adoption of tools such as RSB represents a strategic step towards sustainability with credibility.
