The world's interest in reducing petroleum use has led to the rapid development of the biofuel industry over the past decade or so. However, there is increasing concern over how current food-based biofuels affect both food security and the environment. Second-generation biofuels, however, use widely available sources such as non-food lignocellulosic-based biomass and fats, oils, and greases. They make practical consideration of how land use can simultaneously support both the world's food needs and some of its energy needs. This volume consolidates some of the most recent investigations into these issues. The chapters focus on these categories of research: The problems currently connected with biofuels relating to land use and the environment Investigations into the potential for land use to be managed more effectively and sustainably Research that focuses on new and developing options for second-generation biofuels This volume is recommended for all biofuel researchers, from the PhD student to the experienced scientist. It also offers an essential foundation to anyone interested in how biofuels relate to the future of our world.

While energy prices, energy security, and climate change are front and center in the national media, these issues are often framed to the exclusion of the broader issue of sustainability--ensuring that the production and use of biofuels do not compromise the needs of future generations by recognizing the need to protect life-support systems, promote economic growth, and improve societal welfare. Thus, it is important to understand the effects of biofuel production and use on water quality and quantity, soils, wildlife habitat and biodiversity, greenhouse gas emissions, air quality, public health, and the economic viability of rural communities.

In December 2007, the Congress expanded the renewable fuel standard (RFS), which requires rising use of ethanol and other biofuels, from 9 billion gallons in 2008 to 36 billion gallons in 2022. To meet the RFS, the Departments of Agriculture (USDA) and Energy (DOE) are developing advanced biofuels that use cellulosic feedstocks, such as corn stover and switchgrass. The EPA administers the RFS. This report examines, among other things: (1) the effects of increased biofuels production on U.S. agriculture, environment, and greenhouse gas emissions; (2) federal support for domestic biofuels production; and (3) key challenges in meeting the RFS. Includes recommendations. Charts and tables.

Biofuels made from algae are gaining attention as a domestic source of renewable fuel. However, with current technologies, scaling up production of algal biofuels to meet even 5 percent of U.S. transportation fuel needs could create unsustainable demands for energy, water, and nutrient resources. Continued research and development could yield innovations to address these challenges, but determining if algal biofuel is a viable fuel alternative will involve comparing the environmental, economic and social impacts of algal biofuel production and use to those associated with petroleum-based fuels and other fuel sources. Sustainable Development of Algal Biofuels was produced at the request of the U.S. Department of Energy.

Biofuels global emergence in the last two decades is met with increased concerns over climate change and sustainable development. This report addresses the core issue of biofuel sustainability of biofuels and related feedstocks, drawing from a wide range of sustainability related studies, reports, policy initiatives. The report critically examines the economic, environmental and social sustainability dimensions of biofuels and review the major certification initiatives, schemes and regulations. In doing so, the report relies on extensive review of a number of country case studies covering a broad range of current biofuel-feedstocks systems. The report analysis clearly distinguish feedstock efficiency (in terms of biofuel yields per unit of land) from sustainability, especially under limiting resource (irrigated water) or sensitive areas (carbon stocks). Also, long run economic viability depend on the future policy support, technical innovations in biofuel systems, economics of biofuel supply and demand and trade-offs between food and energy uses as well as feedstock productivity gains. Biofuels can present both advantages and risks for environmental sustainability; the latter being often difficult to measure or monitor and may conflict with economic sustainability unless great strides in productivity gains are achieved. Social sustainability is the weakest link in current biofuel certification schemes owing to intrinsic local factors and as efforts target more few negative social impacts; much less focus is placed on inclusive processes that strengthen marginal stockholders participation and benefits. Biofuel certification schemes need to be more smallholder inclusive, perhaps through policy initiatives. Finally, poor developing countries, especially with abundant land and biomass production potential, need to prioritise food security and poverty reduction. In many cases, biofuel models that encourage small scale integrated bioenergy systems may offer higher rural development impacts. FDI-induced larger-scale biofuel projects, on the other hand, may be suitable in those situations where countries have sufficient industrial capacity, besides land and biomass potential, and when these biofuel projects can be fully integrated into domestic energy strategies that do not conflict with food production potential and food security.

Fossil independence and substantial reductions in CO2 emissions seem to be possible with 2nd generation biofuels. New technologies allow a full carbon-to-fuel conversion of non-edible plant parts such as straw or wood, and the cultivation of algae or salt-resistant plants uncouples bioenergy from food production. Nevertheless, impacts on biodiversity, global land and water use are widely unclear and their competitiveness with 1st generation biofuels and electric mobility is an open question. An interdisciplinary team of Empa, University of Zurich and the Institute of Climate, Environment and Energy in Wuppertal evaluated the most sustainable production techniques and assessed their potential for our future mobility.

The Energy Independence and Security Act (EISA) of 2007 established specific targets for the production of biofuel in the U.S. Meeting these targets will increase demand for traditional ag. commodities used to produce ethanol, resulting in land-use, production, and price changes in the farm sector. This report summarizes the estimated effects of meeting the EISA targets for 2015 on regional ag. production and the environment. Meeting EISA targets for ethanol production will expand U.S. cropped acreage by 5 million acres by 2015, an increase of 1.6% over what would otherwise be expected. Much of the growth comes from corn acreage, which increases by 3.5% over baseline projections. Water quality and soil carbon will also be affected.
