Harmonised national greenhouse gas emission calculators

User-friendly greenhouse gas calculators have been developed in Germany, the Netherlands, Spain, and the United Kingdom. Their templates are adjusted to local production characteristics. However, users cannot add new kinds of input values or influence the calculation formula (as they can do in the BioGrace excel calculation tool). The BioGrace consortium came into cooperation with the owners of the national calculators seeking  harmonisation by requesting them to use the same standard values. The calculators now produce the same results when entering the same input figures as can be concluded by the following comparison table.
