We are pleased to announce the update of our 2BS biofuel GHG calculator. From 1 June 2026, calculator v7 will come into effect. It must be used for all your GHG calculations from that date. In the context of your audits, no calculation using the previous version (v6.63) will be accepted.
This new version is available in two formats:
- A dematerialised online calculator, accessible here (recommended format)
The results produced by this tool are considered compliant by default during the audit. However, the auditor will verify the raw values entered.
- A calculator in Excel format, downloadable from your personal account.
The calculations performed in this file will be reviewed by the auditor to ensure their compliance, particularly in the event of modifications made by the user. The raw values entered will also be checked.
Please note, however, that the use of the 2BS biofuel calculator is not mandatory. What is required is compliance with the calculation methodology described in document 2BS-PRO-03, regardless of the tool used to perform your GHG calculations.
Impact of the update v6.63 -> v7:
This update only affects the EEC factor, in particular, direct and indirect nitrous oxide (N2O) emissions from crop cultivation, which can be found in section 4) of our calculator.
NDirect – N = ((ESN + EON ) •EF 1ij) + [ECR • EF1]
This update mainly concerns the change in the EF1ij emission factor, which is now based on the Stehfest & Bouwman method in accordance with the Implementing Regulation 2022/996.
As a result, several additional parameters must now be entered into the calculator:
- Soil texture
- Soil organic Carbon content
- Crop specification (vegetation)
For areas in France, these parameters are automatically filled in with default classifications if you answer “Yes” in cell D30, using the database of French postal codes and pedoclimatic data.
If you are not in France, as with the previous version, the calculator can be modified to automatically obtain the postal codes and pedoclimatic data for your country, or you can enter them manually. If the default classifications from France are used for one of these parameters, evidence must be provided during the audit to justify the choice made.
If you do not apply the default classifications for France, please answer “No” in cell D30 and fill in the three parameters manually.
Regarding the Stehfest & Bouwman model parameters to be specified, you have access to additional information and a proposal for equivalences between the new input data and those of the IPCC 2019 in the “N2O (Stehfest & Bouwman)” sheet.
- Important: the pH value is now mandatory in the EEC calculator. For France, you can access regional pH values in the “Valeurs Moyennes Régionales” sheet.
- For your information, this update will change the results of the EEC calculation. For dry climates, the results may increase, and for humid climates, they may decrease. However, the results depend on nitrogen (N) inputs and, in particular, the Stehfest & Bouwman classification (soil texture, carbon content, crop type, climate, and pH).
