Les gouvernements de nombreux pays de l’OCDE, mais aussi de plusieurs pays non membres, s’emploient activement à promouvoir la production et la consommation de nouveaux carburants de transport issus de produits agricoles. Le rapport conclut qu’il existe d’autres solutions que les politiques actuelles de soutien des biocarburants qui permettraient aux gouvernements de réaliser plus efficacement leurs objectifs.

En 2007, les biocarburants ont reçu 15 milliards USD de subventions dans les pays membres de l’OCDE. Ont-ils pour autant apporté des bénéfices en termes de protection du climat ou de sécurité énergétique ? Dans le cadre des politiques actuelles, le soutien aux biocarburants n’est pas lié à leurs performances environnementales, alors même que tous les biocarburants sont loin d’afficher le même bilan écologique. A vrai dire, il se pourrait qu’une grande partie de l’éthanol et du biodiesel produit aujourd’hui engendre au bout du compte davantage d’émissions de gaz à effet de serre que les carburants traditionnels que sont l’essence et le diesel. Les rapports réunis dans cet ouvrage examinent la dimension économique des biocarburants et évaluent les perspectives de production de biocarburants conventionnels dans les pays de l’OCDE, les possibilités d’exportation de l’éthanol brésilien et le potentiel de certains biocarburants de seconde génération dans l’optique de l’approvisionnement des marchés mondiaux en carburants. La Table ronde dont ils sont issus a analysé les aspects essentiels qui doivent guider les gouvernements dans la détermination du soutien apporté aux biocarburants, notamment les émissions de gaz à effet de serre produits par ces carburants sur l’ensemble de leur cycle de vie et l’impact plus général des cultures énergétiques sur l’environnement. Sont également analysés, les progrès intervenus récemment en matière d’élaboration de systèmes de certification pour les biocarburants, sachant que ces systèmes sont un outil essentiel pour lier le soutien à l’abaissement effectif des émissions de gaz à effet de serre – qui ne saurait toutefois pas empêcher la destruction des forêts tropicales et leur remplacement par des surfaces consacrées à la production de biocarburants. En conclusion, l’ouvrage présente une courte liste de réformes préconisées pour faire en sorte que les politiques de soutien aux biocarburants contribuent véritablement à l’atténuation des émissions de gaz à effet de serre.

Biofuels received USD 15 billion in subsidies in OECD Member countries in 2007, but did they deliver benefits in terms of climate change or oil security? Present policies make no link between support for biofuels and their environmental performance, and biofuels do not all perform equally well. In fact, much of the current ethanol and biodiesel production may result in higher overall emissions of greenhouse gases than using conventional transport fuels - gasoline and diesel. The papers published in this report examine the economics of biofuels and assess the potential of conventional biofuel production in OECD countries, Brazilian ethanol exports and some second generation biofuels to supply world markets with transport fuels. This Round Table analyses the critical issues for governments in determining support for biofuels, particularly the level of greenhouse gas emissions throughout the life-cycle of these fuels and the wider environmental impacts of farming biomass. It also reviews recent progress in developing certification systems for biofuels – an essential tool for tying support to achievement in reducing greenhouse gas emissions, although certification cannot be expected to prevent rainforest destruction for the development of biofuel crop plantations. The report concludes with a short list of recommendations for policy reform if support for biofuels is to contribute effectively to mitigating greenhouse gas emissions.

Bioenergy has been critical to humanity since the cave dwellers first used wood to cook their food and stay warm at night. Ancient forms of bioenergy ¿ firewood and cow dung patties ¿ remain primary fuel sources for rural and poor people. New sources of bioenergy including ¿black liquor¿, biodiesel, cellulosic ethanol and many more, have great promise and generate great controversy. This book gives an overview of bioenergy developments and examines the main issues and possible socioeconomic implications of these developments and their potential impacts on land use and the environment, especial

A new economic opportunity for sub-Saharan Africa is looming large: biofuel production. Rapidly rising energy prices are expected to remain high for an extended period of time because of the increasing demand in prospering and populous countries such as China and India, the depletion of easily accessible supplies of crude oil, and concern over global climate change. As a result, there is renewed interest in biofuels as an alternative to fossil fuels.Africa is uniquely positioned to produce these new cash crops for both domestic use and export. The region has abundant land resources and prefere

Biochar is the carbon-rich organic matter that remains after heating biomass under minimization of oxygen during a process called pyrolysis. Its relevance to deforestation, agricultural resilience, and energy production, particularly in developing countries, makes it an important issue. This report offers a review of what is known about opportunities and risks of biochar systems. Its aim is to provide a state of the art overview of current knowledge regarding biochar science. In that sense the report also offers a reconciling view on different scientific opinions about biochar providing an ove

Biofuels could provide up to 27% of total transport fuel worldwide by 2050. The use of transport fuels from biomass, when produced sustainably, can help cut petroleum use and reduce CO2 emissions in the transport sector, especially in heavy transport. Sustainable biofuel technologies, in particular advanced biofuels, will play an important role in achieving this roadmap vision. The roadmap describes the steps necessary to realise this ambitious biofuels target; identifies key actions by different stakeholders, and the role for government policy to adopt measures needed to ensure the sustainable expansion of both conventional and advanced biofuel production.

Biofuels and the Globalization of Risk offers a fresh, compelling analysis of the politics and policies behind the biofuels story, with its technological optimism and often-idealized promises for the future. This essential new critique argues that investment in biofuels may reconfigure risk and responsibility, whereby the global South is encouraged to invest its future in growing biofuel crops, often at the expense of food, in order that the global North may continue its unsustainable energy consumption unabated and guilt-free. Thus, Smith argues, biofuels may constitute the biggest change in North--South relationships since colonialism.
