The methodology follows the Intergovernmental Panel on Climate Change (IPCC) guidelines for national greenhouse gas inventories and is supported by comprehensive global data collected by the JRC. The methodology was the basis for the Commission decision on the guidelines for the calculation of land carbon stocks.

The new system, adopted in June by the European Commission, encourages industry, governments and NGOs to set up voluntary certification schemes for all types of biofuels.

It will help to ensure that all biofuels (including those imported into the EU) are sustainable and deliver high greenhouse gas (GHG) savings, at least 35% when compared to fossil fuels. It also excludes specific land categories, such as primary forests, wetlands, peatlands and areas with high diversity.

The JRC provided extensive technical and scientific support to the Commission Directive and Communications. This included designing practical measures and procedures for calculating the GHG emissions of various options for producing biofuels and bioliquids. The accompanying global data layers on climate regions and soil types have also been developed by the JRC, following IPCC specifications.

The standard methodology and the carbon stock coefficients together with the data layers will enable economic operators to determine what changes in land carbon stocks might arise from the conversion of land for biofuels production.

The calculation of default values for GHG savings is a complex procedure, which must take into consideration a number of parameters such as the type of fertiliser or pesticide used when growing biofuels, the fuel used by agricultural vehicles (tractors) or the distance to the processing plant and users.

Other JRC contributions included:

Calculating the typical and default values for GHG savings (Annex V of the Directive 2009/28/EC "on the promotion of the use of energy from renewable sources");

Adapting and updating the list of pathways to technical and scientific progresses;

Selecting the most scientifically appropriate data sources;

Providing technical answers and support to third parties on the assessment of GHG emissions and on the values specified in the Directive.

Background
The package adopted on 10 June 2010 by the European Commission, in support of the 2009/28/EC Directive, provided for:

Sustainable biofuel certificates: The Commission encourages industry, governments and NGOs to set up 'voluntary schemes' to certify biofuel sustainability and explains the standards these must meet to gain EU recognition. One of the main criteria is that they have independent auditors which check the whole production chain, from the farmer and the mill, via the trader, to the fuel supplier who delivers petrol or diesel to the filling station. The Communication sets standards requiring this auditing to be reliable and fraud-resistant.

Protecting untouched nature: The Communication establishes that biofuels should not be made from raw materials from tropical forests or recently deforested areas, drained peatland, wetland or highly biodiverse areas. It also provides guidelines for the assessment, making clear for instance that the conversion of a forest to a palm oil plantation would fall foul of the sustainability requirements.

The promotion of biofuels with high greenhouse gas savings: The Communication reiterates that EU countries have to meet binding national targets for renewable energy and that only those biofuels with high greenhouse gas savings count towards those targets. It also explains how to calculate those savings. Biofuels must deliver greenhouse gas savings of at least 35% compared to fossil fuels, rising to 50% in 2017 and to 60%, for biofuels from new plants, in 2018.
