This paper provides an overview of different certification systems, initiatives and approaches related to biofuels sustainability. The existing certification systems in the field of agriculture and forestry provide a useful and practical experience for the development of a biofuels sustainability certification

A 10% binding minimum target was proposed and included in the new RES Directive proposed in January 2008 to be achieved by all Member States by 2020. This paper aims to investigate the impact of the biofuels production and corresponding land requirements for EU 27 countries for reaching the 2020 target, based on an estimated demand for biodiesel and bioethanol for the EU27. Several scenarios were proposed, based on the assumption that part of the biofuels use will be domestically produced while another part will be imported and on a possible contribution of second generation biofuels up to a maximum of 30%. The assessment of the land requirements for producing biofuels were based on the present practices for agricultural production, current yield and the assumptions for a moderate yield increase of crop production in different countries and also on the technology performances for different feedstock. The analysis concludes with a discussion of the impact of biofuels on agricultural land use in the EU-27 based on the proposed scenarios.

In order to explore the possibilities to use these resources, the research was made on the opportunities to use biomass CHP plants in three main scenarios based on characteristics of heat demand and electricity generation. Since there is not enough available data on typical industrial needs which would be generally applicable in Vojvodina, in all three scenarios, the heat demand was taken into account only according to possibilities of the usage of hot water in district heating systems. The presumption was that the temperature of the steam extraction used for heating purposes should be 120°C. For this reason, in the following research the CHP plant which was examined was a cogeneration power plant which has the steam turbine with one controlled extraction and the condenser for the purpose of maximising the production of electricity when it is possible. Steam parameters at the i...

The report describe the developments in the overall contribution of renewable energy in each Member State since 2005 according to their first Progress Reports, the progress made in the use of each renewable energy source and their share in heating and cooling, electricity and in transport sector.

The comparative evaluation of these experiences indicates the extent of political commitment, often at the highest levels of government, and the significant progress made in developing a framework of policies and infrastructures having geographic information as a core focus. Whilst the political and institutional efforts to comply to the accession criteria are not the main driving force behind the development of GI policies and infrastructures, it clearly is contributing by raising the political profile and securing momentum. The paper is organized into five sections providing the short introduction, overview of the accession process, comparison of the twelve countries in respect to their characteristics, summary of the role of GI in the accession process, and conclusions respectively.

The assessment provides the amount of the residues produced, collected, their present uses and the residues left available for bioenergy. This study considers the crop production and yields and multi-annual yield variation for each crop. The calculation was based on specific residues to product ratios, which were determined, depending on the crop type and crop yield. Sustainable removal rates were considered in order to protect soil fertility. The results show large spatial and temporal variations of available crop residues within EU27. The average amount of crop residues available for bioenergy in EU27 was estimated at 1530 PJ/year, with a variation between 1090 and 1900 PJ/year. The average value represents about 3.2% in final energy consumption in the EU27 while the variation 2.3-4%. This variation, which is even larger at the level of Member States, may result in shortages in biomass supply in some years, when crop residues are available in a lower amount than the average.

The evaluation is geographically explicit at the scale of 1 km(2) and is based on two main computational steps. In the first step the amount of crop residues resulting from statistical assessment based on the methodology developed by Scarlat et al. [1] have been spatially allocated on the EU-27(1) territory using several auxiliary geospatial layers describing, for example, land cover, expected biomass productivity derived from soil parameters, climatic zones and topographical conditions. In the second step the number of model power plants (i.e., plants with a size of 50 MW thermal input and a raw material demand of about 100 kt/yr might be conveniently fed with available crop residues was estimated on the basis of two different allocation strategies implying a different grade of optimization. The results show that the estimated crop residue resources in EU-27 could provide fuel for about 850 plants expected to produce about 1500 PJ/yr. Mobilization needs for the residues are also estimated, leading to a total amount of 1.5 x 10(12)-2 x 10(12) tkm are necessary for the full potential exploitation.

This study aims to quantify the impact of 2020 bioenergy targets on the land use in the EU, based on the projections of the National Renewable Action Plans in four scenarios: Scenario 1. Bioenergy targets according to NREAPs; Scenario 2. Bioenergy targets according to NREAPs, no second generation biofuels; Scenario 3. Bioenergy targets according to NREAPs, reduced import of biofuels and bioliquids; Scenario 4. Bioenergy targets according to NREAPs, high imports of biofuels and bioliquids. This study also considers the credit for co-products generated from biofuel production. The analysis reveals that the land used in the EU for bioenergy would range between 13.5 Mha and 25.2 Mha in 2020. This represent between 12.2% and 22.5% of the total arable land used and 7.3% and 13.5% of the Utilised Agricultural Area (UAA). In the NREAPS scenario, about 17.4 Mha would be used for bioenergy production, representing 15.7% of arable land and 9.4% of UAA. The increased demand from biofuels would lead to an increased generation of co-products, replacing conventional fodder for animal feed. Considering the co-products, the land used for bioenergy would range between 8.8 Mha and 15.0 Mha in 2020 in the various scenarios. This represent between 7.9% and 13.3% of the total arable land used in the EU and 4.7% and 8.0% of the UAA. In the NREAPS scenario, when co-products are considered, about 10.3 Mha would be used for biofuels, bioliquids and bioenergy production, representing 9.3% of arable land and 5.6% of agricultural land. This study further provides detailed data on the impact on land use in each Member State.

A large number of national and international initiatives lately experienced rapid development in the view of the biofuels and bioenergy targets announced in the European Union, United States and other countries worldwide. The main certification initiatives are analysed in detail, including certification schemes for crops used as feedstock for biofuels, the various initiatives in the European Union, United States and globally, to cover biofuels and/or biofuels production and use. Finally, the possible way forward for biofuel certification is discussed. Certification has the potential to influence positively direct environmental and social impact of bioenergy production. Key recommendations to ensure sustainability of biofuels/bioenergy through certification include the need of an international approach and further harmonisation, combined with additional measures for global monitoring and control. The effects of biofuels/bioenergy production on indirect land use change (ILUC) is still very uncertain; addressing the unwanted ILUC requires sustainable land use planning and adequate monitoring tools such as remote sensing, regardless of the end-use of the product.
