RSB Greenhouse Gas Tool

Click the box below to access our GHG Calculator (no cost) or continue reading for  details on other GHG calculation options.

Biofuels applying for RSB certification are required to demonstrate a minimum 50% reduction on GHG from fossil fuels. You can use the above lifecycle GHG calculator developed by the RSB, in collaboration with the Swiss Federal Institute for Materials Testing (EMPA), Quantis and HTW Berlinto, to input your data to obtain GHG intensities for crop production, transport and processing.

Donwload our User’s Manual which provides a step-by-step guide to the RSB GHG tool, which is freely available to any user who would like to utilize it. 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 EU Renewable Energy Methodology.

Other GHG Calculation Options

As an alternative to the RSB GHG tool above, you can use any of the following to calculate your GHG values:

  • Biograce GHG calculation tool
  • Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) Model developed and maintained by the Argonne National Laboratory
  • GHGenius Model for sugarcane ethanol and UCO biodiesel traded into Canada
  • Default Values set by the EU Renewable Energy Directive, Annex V (2009/28/EC) if the specifications as defined by the Directive are met (e.g. feedstock, process,  process energy)
  • RSB offers the option of operators carrying out their own calculation to EU RED or other well-accepted methodologies
