GHG calculation tool for liquid biofuels






Since 2009 all actors in biofuel production have to perform a greenhouse gas calculation in ordert o proof compliance with a saving target. The legal background are:

  • the Renewable Energy Directive (2009/28/EC)
  • the Fuel Quality Directive (2009/30/EC)
  • the German ordinances on sustainability (Biokraft-NachV, BioSt-NachV).

Two Excel based calculation tools have been developed in order to assist market players, certification bodies and auditors with calculating and verifying:

ENZO2-Logo ENZO2 was developed by IFEU and focuses on user friendliness and the application on the German market. It is recognised by the German Federal Office for Agriculture and Food (BLE).

BiograceI-Logo BioGrace I was prepared with the assistance of IFEU in the framework of a EU financed project. It currently is managed by IFEU. It creates transparency regarding the calculation of default values and allows to calculate actual values. It was recognised by the European Commission.

Both tools are harmonised. With their recognition they can be used in combination with a certification scheme to calculate the greenhouse gas emissions and savings.

We offer consultancy and training for both tools. Feel free to contact us!
