GHG Calculator

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

The RSB GHG lifecycle calculator is a free tool available to producers, processors, and all other parts of the supply chain. The GHG calculator enables you to see easily whether you meet the RSB minimum 50% reduction of GHG from fossil fuels.

Anyone applying for RSB certification is required to demonstrate a minimum 50% reduction of GHG from fossil fuels.

RSB GHG Calculator Tool

Download our User’s Manual which provides a step-by-step guide to the RSB GHG tool, which is freely available to any user. If you’d like to do your own calculation without using RSB’s online calculator, look at RSB GHG Calculation Methodology (RSB-STD-01-003-01) which describes the methodology as implemented in the calculation tool, or the EU Renewable Energy Methodology.
