Introduction

The Renewable Energy Directive[1] (the Directive) sets out sustainability criteria for biofuels and bioliquids. For biofuels, corresponding criteria are set out in the Fuel Quality Directive[2]. They apply to biofuels and bioliquids produced in the EU and to imported biofuels and bioliquids.

A part of these sustainability criteria is a mechanism to ensure that the biofuels and bioliquids used to meet EU targets have greenhouse gas savings of at least 35% compared to the fuels they replace[3] when substituting fossil fuels with biofuels. In order to facilitate compliance with this criterion, the Directive contains in part A of Annex V default values for greenhouse gas savings for different fuel production pathways.

As a general rule, producers may always cite a default value for the biofuel and the bioliquid they supply, as an alternative to calculating an actual value. However, for raw materials cultivated in the Union, default values may only be used if the raw materials are cultivated in areas included in lists submitted by Member States, where emissions from cultivation can be expected to be lower than or equal to those reported under part D of Annex V of the Directive[4].

The Directive requires the Commission to report, by 31 March 2010, on whether a similar approach could be applied for raw materials cultivated in third countries. This is the report complying with that obligation[5].

This Report uses the article numbers of the Renewable Energy Directive to refer to specific provisions. Table 1 below indicates where corresponding provisions for biofuels are found in the Fuel Quality Directive. References in this Report to "the Directive" refer to the Renewable Energy Directive. Where the Fuel Quality Directive contains a corresponding provision, they apply equally to that Directive.

Article 19: Calculation of the greenhouse gas impact of biofuels and bioliquids | Article 7d: Calculation of life cycle greenhouse gas emissions of biofuels |

Annex V: Rules for calculating the greenhouse gas impact of biofuels, bioliquids and their fossil fuel comparators | Annex IV: Rules for calculating life cycle greenhouse emissions from biofuels |

DEFAULT VALUES FOR GREENHOUSE GAS EMISSIONS

The default values in the Directive divide the greenhouse gas emissions from biofuel and bioliquids production pathways into three parts: "cultivation", "processing" and "transport and distribution". The default values in the Directive are based on the JEC Well-to-Wheel study[6]. The "cultivation" element typically contributes 30 – 70 % of overall emissions, depending on the pathway; "processing" is responsible for 25 – 60 %, and the remaining emissions (often relatively minor, normally in the range of: 2 – 20 %) come from "transport and distribution".

The main constituents of the cultivation element, according to the JEC Well-to-Wheel study, are fertiliser production, machinery emissions and N2O emissions from soil[7]. The last of these accounts for 40 – 70 % of the cultivation emissions (in some cases even more), depending on the pathway. Some examples can be seen in table 2 below, where total cultivation emissions and N2O emissions from soil are compared, together with overall total pathway emissions[8].

Table 2: Greenhouse gas emissions from cultivation compared to total pathway emissions

Cultivation emissions [gCO2eq./MJ] | Total pathway emissions [gCO2eq./MJ] | Cultivation as percentage of total pathway emissions | N2O emissions [gCO2eq./MJ] | N2O emissions as percentage of cultivation emissions |

Sugar beet ethanol | 12 | 33 | 35% | 6,2 | 54% |

Sugar cane ethanol | 14 | 24 | 60% | 6,9 | 47% |

Rape seed biodiesel | 29 | 46 | 63% | 18,0 | 62% |

Sunflower biodiesel | 18 | 35 | 50% | 9,4 | 53% |

Fertiliser production and machinery emissions from cultivation are not expected to be difficult to estimate for different regions. By contrast, N2O emissions show substantial spatial variation and are difficult to estimate. Different approaches to doing this exist and the uncertainty is considerable. In view of the above, this report focuses on the feasibility of reliably estimating regional N2O emissions in third countries.

STATUS OF RESEARCH IN THE FIELD OF N 2 O EMISSISIONS FROM CULTIVATION OF CROPS

There are two different ways of modelling N2O emissions:

- process-based eco-system models replicating the processes and factors causing emissions in the soil;

- statistical techniques identifying correlations between controlling factors and emissions recorded through field measurements[9].

Both approaches can be used to develop emissions factors such as those presented by the IPCC for accounting of greenhouse gas emissions under the UNFCCC. The IPCC proposes three different approaches of increasing complexity according to available data and models. The simplest one is called Tier 1, where emission factors are multiplied by values for e.g. fertilizer application. However, the Tier 1 approach is a broad simplification. An indication of the uncertainty is the -70%, +300% uncertainty range given for the direct emissions default factors provided by IPCC[10] for the Tier 1 approach. Even this range does not capture some field measurements made.[11]

An example of a process based model is the DNDC-model. This was used to calculate the N2O emissions for the European crops presented in the JEC Well-to-Wheel report[12]. A process-based model such as the DNDC model may deliver accurate results, as a range of environmental factors can be considered, including their interactions. Nevertheless, the result hinges on the quality of the input data including the validation over the domain in which it is applied. On a global level with regional resolution, the current available data would not be of sufficient quality.

An alternative to a process based model is a statistical model , such as the one developed by Stehfest and Bouwman (the S&B model). The model represents the frontier of current statistical understanding of N2O emissions. However, the model is uncertain as pointed out by Smeets et al.[13] and some shortcomings exist, in particular;

a) the model is based on around 1000 field measurements, but none of those are from boreal areas,

b) organic soils are excluded since those measurements strongly influenced the predicted emission from mineral soils,

c) crop type is recognised as an important parameter for N2O emissions, however, the sample of field measurements used as a basis of the model is not extensive enough to cover all crops. There is thus a need to improve the statistical model by reducing its uncertainties by increasing the amount of field measurements under varying conditions[14].

The Joint Research Centre (JRC) of the Commission is working on analysis of N2O emissions disaggregated down to regional level. The current level of sophistication is a global implementation of the Stehfest and Bouwman model[15] for a range of crops used for biofuels and bioliquids. However; the accuracy of the input data, together with the fact that most biofuels and bioliquids fall under the grouping "other crops", when crop type is of major importance for determining the emissions, strongly suggests that this work does not now provide the basis for binding legislative proposals.

APPROPRIATE ACTION TO ADDRESS THE UNCERTAINTY OF N 2 O EMISSIONS FROM CULTIVATION IN THIRD COUNTRIES

The understanding of factors influencing N2O emissions from agricultural soils is evolving rapidly, but is still rather limited. In the light of this a better understanding of the issue is needed before attempts can be made to address the issue in relation to third countries.

The Commission has made the results obtained by the current work of JRC available on its website, together with a description of the methodology and the data used. In doing this, the Commission aims to obtain feedback on the methodology and the data used, in order to improve the modelling, which at a later stage might serve as a basis for a legislative proposal. Of particular relevance is the improved understanding of N2O emissions from crops typically cropped in third countries, and the inclusion of those in N2O models. Statistical data on key parameters, such as soil characteristics, fertilizer use and yields are also limited in some regions and need attention.

CONCLUSION

Article 19(4) of the Directive requires the Commission to assess the feasibility of extending this requirement to third countries. In light of above, the Commission is of the view that, while desirable, it is not yet feasible to set up legally binding lists of areas for third countries where a major component of the underlying calculation is uncertain and can easily be

questioned, and where third countries have had no possibility to contribute on the methodology and data used.

It is therefore not appropriate, at least at this stage to produce legislative lists for third countries based on the current modelling of N2O emissions from agriculture. However, it is important to enhance the understanding of the topic and survey the data used in view of a new assessment in 2012. The Commission has thus published the preliminary results of the JRC work together with all necessary data and description of methodology to support such a process on the webpage of the JRC[16]. It will use this as the basis for a discussion with third countries in the framework of its dialogue and exchange with them under Article 23(2) of the Renewable Energy Directive.

[7] IPCC default methodology assumes that continuous cultivation on mineral soils without changing cultivation practices does not change the soil carbon content. According to the same methodology, continuous cultivation on organic soils leads to significant soil carbon losses. However, a very limited amount of crops are grown on organic soils in the EU. Consequently, the JEC Well-to-Wheel study, which describes typical circumstances, does not include soil carbon changes from cultivation.
