Background There exist ongoing efforts to sustainably meet the world's ever-increasing energy demands. How will biofuel production affect food security and poverty? Plant-based fuel can be produced almost anywhere, comes from a renewable resource and often produces . Currently there are about 3,500 fueling stations in the U.S. that offer E-85 fuel, most of which are in the upper Midwest. Opt not to print. Currently, palm oil plantations coverage is 16 million hectares. 4.6 How could an environmentally sustainable biofuel production be ensured? biofuels production will be Similar to petroleum fuels, biofuels are flammable (especially ethanol) and must be transported carefully. Environmental Impact Biofuel and the Environment Biofuels allow us to power our lives with a 100% renewable, climate-friendly supplement to petroleum-based fossil fuels. Africa, in particular, has not benefitted from modern Reports requested by congress or otherwise deemed important. Burning either fossil fuels or biomass releases carbon dioxide (CO 2 ), a greenhouse gas. This UNESCO-SCOPE-UNEP Policy Brief examines to what extent biofuels can deliver the benefits that are motivating countries and companies to invest heavily in biofuels production. biofuels, and the IEA Currently available biofuels are made from sugar crops (sugarcane, sugarbeet); starch crops (corn, potatoes); oilseed crops (soybean, sunflower, rapeseed); and animal fats. conservation agriculture, and good forestry practices, can Blue Biofuels produces a fuel that is gentler on our environment, providing a non-toxic, cost-effective alternative with a low carbon footprint. and phosphorous into surface and groundwaters. techniques to assess the environmental impact offer a good Because we can convert biofuel from virtually any cellulosic biomass, we can rely on high-yield, abundant plant materials. (2015) implemented the following technical advances for improvising the production of biofuel using a large-scale production system along with reducing the capital cost at two different places with 100 ha capacity. What are the environmental impacts of biofuel production? Biofuels can be regarded as a rather green source of energy since the overall adverse impact on our environment is significantly lower compared to conventional fuels. EPA is soliciting additional comments on the updated list of candidates nominated for an external expert panel for the review of EPAs draft document, Biofuels and the Environment: Third Triennial Report to Congress (RtC3), Biofuels Report to Congress Contact Us page, Energy Independence and Security Act (EISA), Biofuels and the Environment: the First Triennial Report to Congress (2011), State BIOEnergy Primer: Information and Resources for States on Issues, Opportunities, and Options for Advancing Bioenergy, Boutique Fuels Report to Congress (EPA/420/R-06/901), The Plain English Guide to the Clean Air Act, Biofuels and the Environment: the First Triennial Report to Congress (2011 Final Report), Biofuels and the Environment: The Second Triennial Report to Congress, In Aug 2022, EPA put out a call for the public to review and comment on a few additional candidates to serveon the external peer review committee. How are biofuel markets and production evolving? In some parts of the world, large areas of natural vegetation and forests have been cleared or burned to grow soybeans and palm oil trees to make biodiesel. Biofuel production can have serious negative environmental impacts. 2. conversion. Maps by energy source and topic, includes forecast maps. One of the most pressing implications of the biofuel program is the potential land-use change, as it could drive other issues such as deforestation, GHG emission, and social conflict. The overarching conclusions of this first reportwere: (1) the environmental impacts of increased biofuel production and use were likely negative but limited in impact; (2) there was a potential for both positive and negative impacts in the future; and (3) EISA goals for biofuels production could be achieved with minimal environmental impacts if best practices were used and if technologies advanced to facilitate the use of second-generation biofuel feedstocks (cornstover, perennial grasses, woody biomass, algae, and waste). Throughout the whole life cycle, neglecting any significant impacts and shifting any environmental burdens from one impact to another must be avoided. 06/25/2018. The environmental impacts of producing biofuels from algae include not only climate change but also other impacts. forest and 1.6 billion on marginal land where food crops cannot strive. Greenhouse gas balances differ widely depending on the type of crop, on the location, and on how feedstock production and fuel processing are carried out. Regarding non-GHG environmental impacts, research suggests that production of biofuel feedstocks, particularly food crops like corn and soy, could increase water pollution from nutrients, pesticides, and sediment (NRC 2011). By-products from biofuel production such as proteins for animal feed make a positive contribution to climate change mitigation because they save energy and greenhouse gas emissions that would otherwise have been needed to produce the feed by other means. Repaying this carbon debt could take decades or even hundreds of years. Noting observed increases in acreage for corn and soybean production in the period prior to and following implementation of the RFS2 Program, the2018 Report concluded that the environmental and resource conservation impacts associated with land use change were likely due, at least in part, to the RFS and associated production of biofuel feedstocks. production, water is used in large quantities for washing plants Conversion of forest or In July 2013,EPA continuedto advance it's understanding of the environmental costs and benefits of biofuels to society through several recent research efforts and published papers that were added to the EPA web site. More Changes in land-use and intensification of agricultural Departments of Agriculture and Energy, to assess and report triennially to Congress on the environmental and resource conservation impacts of the RFS Program. Second, the effects of these changes to land use can effect food prices making food accessibility more difficult for the poor. The carbon dioxide is then released back into the atmosphere when the fuel is burnt. Making best use of the remaining limited supplies of fossil fuels. A useful tool to determine the environmental impact of the biofuels is the life cycle analysis (LCA), i.e., the evaluation of the . New How much ethanol is produced, imported, exported, and consumed in the United States? The lack of environmental regulations for biofuels is especially troubling because most biofuelsif one also accounts for the practices used to produce themactually release more greenhouse gases than traditional fossil fuels, Gonzalez argues. Cancer rates and mortality, types and causes, Endocrine disrupting properties of pesticides. Fossil fuels, on the other hand, pull trapped carbon from underground, releasing new greenhouse gases into the atmosphere when consumed. 6. rapeseed, maize or other cereals. Comprehensive data summaries, comparisons, analysis, and projections integrated across all energy sources. tillage and reducing fertilizer and pesticide inputs. cover and organic carbon levels compared with annual crops like This balance helps to restore environmental health by slowing global warming and other GHG-driven impacts. After excluding forest land, protected areas Emissions of nitrous oxide are another important factor. The report describes biofuels produced in 2010 and those projected to be produced and consumed by 2022, reviews model projections and other estimates of the relative . Industrialized countries have subsidized the use of biofuels in an effort to reduce greenhouse gas emissions. Official websites use .gov Federal mandates for biofuel production promote expanded crop acreage which can shift cropping patterns and affect livestock production due to higher prices for corn and other grain crops. On the whole, the net impact on acid rain production is usually negative, meaning biofuels can reduce acid rain. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas. Finally, for bioenergy to be developed sustainably, national In 2013, the EPA's National Center for Environmental Economics ( NCEE ) conducted a meta-analysis that found every one billion gallons of ethanol mandated by the RFS contributes to a 2 to 3% rise in corn prices. Monthly and yearly energy forecasts, analysis of energy topics, financial analysis, congressional reports. The production of biofuel can have nothing but a positive impact on the environment. Both biofuels proponents and critics question how production decisions and policy formulation and development surrounding the rapid expansion of the biofuel industry will affect the environment, especially water quality and soil quality. Sales, revenue and prices, power plants, fuel use, stocks, generation, trade, demand & emissions. Cellulosic ethanol feedstock includes native prairie grasses, fast-growing trees, sawdust, and even waste paper. Most studies have found that producing first generation biofuels usually yields reductions in greenhouse gas emissions of 20 to 60% when fossil fuels are replaced provided the most efficient systems are used and carbon dioxide emissions from changes in land-use are excluded. biodiversity can be cellulose Such low levels of genetic diversity increase the susceptibility A lock (LockA locked padlock) or https:// means youve safely connected to the .gov website. "Biofuel" is a major buzzword in transportation circles these days, and for good reason. framework for bioenergy and food security. For example in Malaysia oil palm expansion has already eradicated vast tracts of forest and now the surging global demand for . For assistance/questions about this website please use the Biofuels Report to Congress Contact Us page. in countries that would otherwise have a comparative advantage. perennial plants. However, the biggest Even though space flight involves leaving the Earth, like every other sector, it is contending with its environmental impact. Regional energy information including dashboards, maps, data, and analyses. However, changes in land use can have dramatic effects on greenhouse gas emissions. Lesson plans, science fair experiments, field trips, teacher guide, and career corner. Increases in irrigation and ethanol refining could deplete aquifers (NRC 2011). Biofuels are derived from renewable biological materials such as ethanol from corn starch, corn stover, perennial grasses, woody biomass, and algae, and diesel from soybeans. the loss of habitat. Of the principal California buys much of its ethanol from the states in the nation's Corn Belt- including a third of Nebraska's annual production. This summary is free and ad-free, as is all of our content. From fast-growing crops to agricultural waste, such as bagasse from the sugarcane industry. Removing plant residues that would otherwise nourish the soil 4.5 How will biofuel production affect biodiversity? The impacts depend on the way the land is farmed. 4.2 What changes to agricultural land would biofuel production require? When consumed as biofuel, they release this back into the atmosphere in a closed loop, emitting only small amounts of new CO2 into the atmosphere from the energy used in our efficient CTS process. methods and standards. and seeds and for evaporative cooling. Oils and animal fats can be processed into biodiesel. Some effects are easily noticed (for example, odors emanating from an ethanol plant). compromised where large-scale production is practiced. soil quality, especially on soil organic content. Energy use in homes, commercial buildings, manufacturing, and transportation. As Timothy D. Searchinger, a researcher at Princeton University's Centre for Energy and Environmental Policy Research, points out: "A quarter of CO 2 emissions come from land-use change, deforestation . feedstock production are Studies that have considered the ultimate impacts of biofuels have consistently found corn-grain ethanol to have human health damage costs equal to or higher than gasoline (Hill et . affect wild and agricultural An often mentioned incentive for using biodiesel is its capacity to lower greenhouse gas emissions compared to those of fossil fuels. Biofuels . Where do hydrocarbon gas liquids come from? Measuring Biofuel Environmental Impacts. The Environmental Advantages of Biofuel. Production and use of biofuels is considered by the U.S. government to have fewer or lower negative effects on the environment compared to fossil-fuel derived fuels. . require some irrigation during hot and dry summers. a loss of wild biodiversity in these areas. Through our work with the USDA, we have proven that king grass can sustainably grow on previously disused, unproductive farm lands in South Florida with little effort. Overview of Atmospheric Pollutants . U.S. Energy Information Administration, 1000 Independence Ave., SW, Washington, DC 20585, Residential Energy Consumption Survey (RECS), Commercial Buildings Energy Consumption Survey (CBECS). grown on poor-quality land, and soil carbon and quality will There are also potential national economic and security benefits when biofuel use reduces the need to import petroleum fuels. biofuel crop production. Using biofuels to help power jet engines reduces particle emissions in their exhaust by as much as 50 to 70 percent, in a new study conclusion that bodes well for airline economics and Earth's environment. Biofuels affect the environment at all stages of their production and use. (1) Effects on food security: There are two main effects the expansion of biofuels can have on food security. Again, the solution to this problem may be algae. Whether this is true or not depends on many factors. Growing plants for fuel is a controversial topic because some people believe the land, fertilizers, and energy used to grow biofuel crops should be used to grow food crops instead. Biofuels Environmental Impact Biofuels Environmental Impact Some intensive up to date ranch procedures utilised for nourishment output have a variety of contradictory consequences on the natural environment, for example dirt erosion, water lack, contamination from pesticides and difficulties with over use of fertilizers (including . Similarly, care will be required when dealing with one requiring the greatest amount of fertilizer and pesticides The combustion of petrol and diesel produces many different types of local air pollutants. Forms EIA uses to collect energy data including descriptions, links to survey instructions, and additional information. sustainability criteria or Reserves, production, prices, employment and productivity, distribution, stocks, imports and exports. The environmental concerns about biofuel Production and use of biofuels is considered by the U.S. government to have fewer or lower negative effects on the environment compared to fossil-fuel derived fuels. EPA, in consultation with USDA and DOE, is currently developing the third report to Congress, which will build on the conclusions of the previous two reports. Solid biofuels have a greater potential than liquid biofuels as a significant energy source and currently contribute over 10% of global energy. Crops such as eucalyptus, poplar, willow or grasses can be According to an Oxfam study, by 2020 Europe's biofuels policy will result in 16% higher prices for plant oils, 10% higher prices for oilseeds and an estimated 2.6% average increase in global crop prices.These substantial increases are caused by the implementation of just one policy in just one region, the EU. complementary methodologies are being developed to assess It also mitigates the effects of global warming which is caused by the use of fossil fuels. But that battery does not have an infinite shelf-life. Access resource conservation impacts, including soil conservation, water availability, land use changes, and ecosystem health and biodiversity. Thats enough to replace half the transportation fuels used in the entire world. Land requirements and availability . . hectares cropland. Using biomass for energy has positive and negative effects Biomass and biofuels made from biomass are alternative energy sources to fossil fuelscoal, petroleum, and natural gas. production both have the potential to harm soil condition, but A literature review was performed to highlight issues related to the growth and use of algal products for generating biofuels. Another benefit to biofuels is the reduced danger of an environmental disaster. A significant factor contributing to greenhouse gas emissions is the amount of fossil energy used for feedstock production and transport, including for fertilizer and pesticide manufacture, for cultivation and harvesting of the crops, and or in the biofuel production plant itself. Opportunities for public engagement will be announced in Federal Register Notices. biodiversity and landscape Biodiesel - The Good. concerns, since some of the proposed plant species can be Renewable Fuel Standard evaluates the economic and environmental consequences of increasing biofuels production as a result of Renewable Fuels Standard, as amended by EISA (RFS2). Biofuels allow us to power our lives with a 100% renewable, climate-friendly supplement to petroleum-based fossil fuels. Global demand for food is expected to double within the coming 50 years ( 31 ), and global demand for transportation fuels is expected to increase even more rapidly ( 32 ). Intensive research has produced significant improvements in Our biomass sources various plant materials capture CO2 from the atmosphere while growing. biodiversity, because of " The push to cut pollutants from shipping is an emerging opportunity for biofuels, but the potential impact has gone relatively unexplored. Three and permanent soil cover that prevents erosion can reduce the Gasoline requires extra processing to reduce evaporative emissions before blending with ethanol. In California, lipids account for the majority of the feedstocks for U.S. non-fuel ethanol biofuels production and also for the majority of credits generated under California's LCFS. Overall, sorghum biofuels provide advantages in environmental impact categories including global warming potential, fossil fuel depletion and eutrophication, showing potential for sorghum as a promising second-generation feedstock for fuel. Fuel Price Stability Because of their potentially lower carbon intensities, some state governments provide more support for biofuels production from lipid feedstocks than for raw, unused vegetable oil feedstocks. potential. Includes hydropower, solar, wind, geothermal, biomass and ethanol. The use of biofuels reduces dependence on imported petroleum products, creates new markets for sustainably grown crops, improves land utilization, reduces environmentally devastating oil spills, and, not least, reduces concentrations of GHG emissions in the atmosphere. 2. area, about 8.3 billion hectares are currently grassland or The level of pollution and habitat destruction directly resulting from biofuel production is alarmingly high. crop yields, but has focused on specific crops and regions. Section 204 of EISA directs EPA, in consultation with the U.S. Biofuel is commonly advocated as a cost-effective and environmentally benign alternative to petroleum and other fossil . If the above technical impediments can be overcome, then the net impact of biofuels on the environment can be limited. Payments for environmental services may also represent an There are various social, economic, environmental and technical issues with biofuel production and use, which have been discussed in the popular media and scientific journals. Burning biofuels results in emissions of carbon dioxide (CO2), a greenhouse gas. well suited for tropical areas, and this creates an economic Crops which do well on fertile soils may not be as effective Ethanol production facility in South Bend, Indiana, Source: Photo courtesy of Wikimedia Commons (public domain). You can help us remain free and independant as well as to develop new ways to communicate science by becoming a Patron! The amount of irrigation water needed in lower rainfall areas On the other hand, biofuels tend to contain high levels of nitrogen, which can form compounds that also lead to acid rain and atmospheric contamination. Biofuel is produced to reduce gas emissions from greenhouses. instrument for encouraging compliance with It released millions of gallons of oil, causing an unknown amount of damage in the process. This can reduce processes that take years in crop plants, down to a few months in algae. less of the maize production in the USA is rainfed. Human exposure and environmental impact issues are identified and discussed, as well as current research and development activities of academic, commercial, and governmental groups. Secondly, an environmental life cycle assessment (LCA) of various biofuels is presented. Some land that was not profitable in the past could be This will have serious impacts on the environment, possibly threatening the natural resource base. realised. Regarding non-GHG environmental impacts, research suggests that production of biofuel feedstocks, particularly food crops like corn and soy, could increase water pollution from nutrients, pesticides, and sediment (NRC 2011). . greenhouse gas emissions, Biofuels from some sources can even generate more greenhouse gas emissions than fossil fuels. southern and eastern Africa and north-eastern Brazil are already Life-Cycle Analysis is the main tool used to do this. Despite "intense study over the last decade" on whether, or to what extent, biofuel production replaces food production and affects the environment, "substantial uncertainties remain on many. However, fuel ethanol contains denaturants to make fuel ethanol undrinkable. In 2004, about 1% of global cropland was being used for 5. Many When crops for biofuel production require irrigation, it exerts pressure on local water resources. well on poor soils than a diverse mixture of native grassland In addition, water quality can be affected by soil erosion and runoff containing fertilizers and pesticides. increase problems of soil erosion and runoff of excess nitrogen In addition, such diverse mixtures can provide Increases in irrigation and ethanol refining could deplete aquifers (NRC 2011). Energy-Related Carbon Dioxide Emissions, Energy-Related Carbon Dioxide Emissions at the State Level, through 2018, Annual Solar Photovoltaic Module Shipments Report, Midwest and Rocky Mountain Transportation Fuels Markets, East Coast and Gulf Coast Transportation Fuels Markets. tend to improve over time. Biofuels, made from crops such as corn, can have negative economic and environmental effects, as well as positive ones. crops such as jatropha, cassava, sweet sorghum, may be able grow Beal et al. when natural landscapes are converted into energy-crop In addition, the impacts of fuel use are compared with other uses for bioenergy such as the generation of . material, with traditional varieties being used less and less. Biofuels, should be water filtration and carbon sequestration than maize or soybean In total, low-input biofuels have the potential to provide much higher NEB ratios and much lower environmental impacts per net energy gain than food-based biofuels. The Impact of Biofuel Mandates on Food and Fuel Prices Biofuel mandates have important effects on food markets. Uranium fuel, nuclear reactors, generation, spent fuel. and land needed for food, between 250 and 800 million hectares, Only 25 to 33% of available crop residues from Biofuel production and use has drawbacks as well, including land and water resource requirements, air and ground water pollution. Type Chapter per hectare. Thus, incorporation of environmental considerations is an important new area for energy planners. When you factor both the reduced emissions and the carbon capture factor, biofuels come out on top.
