Use our online tool to easily calculate your greenhouse gas (GHG) emissions.

The RSB GHG calculator tool incorporates the RSB Global, EU RED and CORSIA GHG Calculation methodologies and is available for free to RSB participating operators and members. Other users may also request access to the tool for a one-off fee of 200 Euros.

The RSB GHG calculator tool enables you to calculate the supply chain GHG emissions of a fuel or material and see easily whether you meet the RSB minimum GHG reduction threshold.

Anyone applying for RSB certification of fuels is required to demonstrate that the fuel achieves a minimum 50% GHG reduction compared with the fossil fuel baseline, or 60% if they are a new installation. For materials (i.e. all non-energy products), a minimum 10% GHG emission reduction is required.
