The report suggested that biofuels may one day offer a viable alternative, but also that "the implications of the use of biofuels for global security as well as for economic, environmental, and public health need to be further evaluated".<a href="#cite_note-IEA-2">[2]</a> and According to Francisco Blanch, a commodity strategist for <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Merrill_Lynch" title="Merrill Lynch">Merrill Lynch</a>, crude oil would be trading 15 per cent higher and gasoline would be as much as 25 per cent more expensive, if it were not for biofuels.<a href="#cite_note-3">[3]</a> Gordon Quaiattini, president of the <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Canadian_Renewable_Fuels_Association" title="Canadian Renewable Fuels Association">Canadian Renewable Fuels Association</a>, argued that a healthy supply of alternative energy sources will help to combat gasoline price spikes.<a href="#cite_note-autogenerated1-4">[4]</a> <h3>"Food vs. fuel" debate[<a href="/web/20150305184539/http://en.wikipedia.org/w/index.php?title=Issues_relating_to_biofuels&action=edit&section=3" title="Edit section: "Food vs. fuel" debate">edit</a>]</h3> <div class="hatnote relarticle mainarticle">Main article: <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Food_vs_fuel" title="Food vs fuel" class="mw-redirect">Food vs fuel</a></div> Food vs fuel is the debate regarding the risk of diverting farmland or crops for biofuels production in detriment of the <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Food_supply" title="Food supply" class="mw-redirect">food supply</a> on a global scale. Essentially the debate refers to the possibility that by farmers increasing their production of these crops, often through government subsidy incentives, their time and land is shifted away from other types of non-biofuel crops driving up the price of non-biofuel crops due to the decrease in production.<a href="#cite_note-babcock-5">[5]</a> Therefore, it is not only that there is an increase in demand for the food staples, like corn and cassava, that sustain the majority of the world's poor but this also has the potential to increase the price of the remaining crops that these individuals would otherwise need to utilize to supplement their diets. A recent study for the <a href="/web/20150305184539/http://en.wikipedia.org/wiki/International_Centre_for_Trade_and_Sustainable_Development" title="International Centre for Trade and Sustainable Development">International Centre for Trade and Sustainable Development</a> shows that market-driven expansion of <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Ethanol" title="Ethanol">ethanol</a> in the US increased maize prices by 21 percent in 2009, in comparison with what prices would have been had ethanol production been frozen at 2004 levels.<a href="#cite_note-babcock-5">[5]</a> A November 2011 study states that biofuels, their production, and their subsidies are leading causes of agricultural price shocks.<a href="#cite_note-6">[6]</a> The counter-argument includes considerations of the type of corn that is utilized in biofuels, often field corn not suitable for human consumption; the portion of the corn that is used in ethanol, the starch portion; and the negative effect higher prices for corn and grains have on government welfare for these products. The "food vs. fuel" or "food or fuel" debate is internationally controversial, with disagreement about how significant this is, what is causing it, what the impact is, and what can or should be done about it.<a href="#cite_note-7">[7]</a><a href="#cite_note-8">[8]</a><a href="#cite_note-9">[9]</a><a href="#cite_note-10">[10]</a> <h3>Poverty reduction potential[<a href="/web/20150305184539/http://en.wikipedia.org/w/index.php?title=Issues_relating_to_biofuels&action=edit&section=4" title="Edit section: Poverty reduction potential">edit</a>]</h3> Researchers at the <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Overseas_Development_Institute" title="Overseas Development Institute">Overseas Development Institute</a> have argued that biofuels could help to reduce poverty in the developing world, through increased <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Employment" title="Employment">employment</a>, wider <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Economic_growth" title="Economic growth">economic growth</a> multipliers and by stabilising oil prices (many developing countries are net importers of oil).<a href="#cite_note-ODI1-11">[11]</a> However, this potential is described as 'fragile', and is reduced where feedstock production tends to be large scale, or causes pressure on limited agricultural resources: capital investment, land, water, and the net cost of food for the poor. With regards to the potential for poverty reduction or exacerbation, biofuels rely on many of the same policy, regulatory or investment shortcomings that impede <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Agriculture" title="Agriculture">agriculture</a> as a route to <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Poverty_reduction" title="Poverty reduction">poverty reduction</a>. Since many of these shortcomings require policy improvements at a country level rather than a global one, they argue for a country-by-country analysis of the potential poverty impacts of biofuels. This would consider, among other things, land administration systems, market coordination and prioritizing investment in <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Biodiesel" title="Biodiesel">biodiesel</a>, as this 'generates more labour, has lower transportation costs and uses simpler technology'.<a href="#cite_note-biofuelsandpovreduction-12">[12]</a> Also necessary are reductions in the tariffs on biofuel imports regardless of the country of origin, especially due to the increased efficiency of biofuel production in countries such as Brazil.<a href="#cite_note-ODI1-11">[11]</a> <h3>Sustainable biofuel production[<a href="/web/20150305184539/http://en.wikipedia.org/w/index.php?title=Issues_relating_to_biofuels&action=edit&section=5" title="Edit section: Sustainable biofuel production">edit</a>]</h3> <div class="hatnote relarticle mainarticle">Main article: <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Sustainable_biofuel" title="Sustainable biofuel">Sustainable biofuel</a></div> Responsible policies and economic instruments would help to ensure that biofuel commercialization, including the development of new <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Cellulosic_ethanol" title="Cellulosic ethanol">cellulosic technologies</a>, is <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Sustainable" title="Sustainable" class="mw-redirect">sustainable</a>.

For co-production of biochar to be widely adopted, the soil amendment and carbon sequestration value of co-produced charcoal must exceed its net value as a source of energy.<a href="#cite_note-17">[17]</a> Some commentators claim that removal of additional cellulosic biomass for biofuel production will further deplete soils.<a href="#cite_note-18">[18]</a> <h3>Impact on water resources[<a href="/web/20150305184539/http://en.wikipedia.org/w/index.php?title=Issues_relating_to_biofuels&action=edit&section=8" title="Edit section: Impact on water resources">edit</a>]</h3> Increased use of biofuels puts increasing pressure on water resources in at least two ways: water use for the irrigation of crops used as feedstocks for biodiesel production; and water use in the production of biofuels in refineries, mostly for boiling and cooling. In many parts of the world supplemental or full irrigation is needed to grow feedstocks. For example, if in the production of corn (maize) half the water needs of crops are met through irrigation and the other half through rainfall, about 860 liters of water are needed to produce one liter of ethanol.<a href="#cite_note-19">[19]</a> However, in the United States only 5-15% of the water required for corn comes from irrigation while the other 85-95% comes from natural rainfall. In the United States, the number of ethanol factories has almost tripled from 50 in 2000 to about 140 in 2008. A further 60 or so are under construction, and many more are planned.

This finding has been backed by reports of the <a href="/web/20150305184539/http://en.wikipedia.org/wiki/UN" title="UN" class="mw-redirect">UN</a>,<a href="#cite_note-70">[70]</a> the <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Intergovernmental_Panel_on_Climate_Change" title="Intergovernmental Panel on Climate Change">IPCC</a>,<a href="#cite_note-71">[71]</a> and some other smaller environmental and social groups as the <a href="/web/20150305184539/http://en.wikipedia.org/wiki/European_Environmental_Bureau" title="European Environmental Bureau">EEB</a><a href="#cite_note-72">[72]</a> and the Bank Sarasin,<a href="#cite_note-73">[73]</a> which generally remain negative about biofuels. As a result, governmental<a href="#cite_note-74">[74]</a> and environmental organizations are turning against biofuels made in a non-sustainable way (hereby preferring certain oil sources as <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Jatropha" title="Jatropha">jatropha</a> and <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Cellulosic_ethanol" title="Cellulosic ethanol">lignocellulose</a> over <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Palm_oil" title="Palm oil">palm oil</a>)<a href="#cite_note-75">[75]</a> and are asking for global support for this.<a href="#cite_note-76">[76]</a><a href="#cite_note-77">[77]</a> Also, besides supporting these more sustainable biofuels, environmental organizations are redirecting to new technologies that do not use <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Internal_combustion_engine" title="Internal combustion engine">internal combustion engines</a> such as <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Zero_emission#Zero_emission_engines" title="Zero emission">hydrogen and compressed air</a>.<a href="#cite_note-78">[78]</a> Several standard-setting and certification initiatives have been set up on the topic of biofuels. The "Roundtable on Sustainable Biofuels" is an international initiative which brings together farmers, companies, governments, non-governmental organizations, and scientists who are interested in the sustainability of biofuels production and distribution. During 2008, the Roundtable is developing a series of principles and criteria for <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Sustainable_biofuel" title="Sustainable biofuel">sustainable biofuels</a> production through meetings, teleconferences, and online discussions.<a href="#cite_note-79">[79]</a> In a similar vein, the <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Bonsucro" title="Bonsucro">Bonsucro</a> standard has been developed as a metric-based certificate for products and supply chains, as a result of an ongoing multi-stakeholder initiative focussing on the products of <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Sugar_cane" title="Sugar cane" class="mw-redirect">sugar cane</a>, including ethanol fuel.<a href="#cite_note-BonsucroGuide-80">[80]</a> The increased manufacture of biofuels will require increasing land areas to be used for agriculture. Second and third generation biofuel processes can ease the pressure on land, because they can use waste biomass, and existing (untapped) sources of biomass such as crop residues and potentially even marine algae. In some regions of the world, a combination of increasing demand for food, and increasing demand for biofuel, is causing deforestation and threats to biodiversity. The best reported example of this is the expansion of oil palm plantations in Malaysia and Indonesia, where rainforest is being destroyed to establish new oil palm plantations. It is an important fact that 90% of the palm oil produced in Malaysia is used by the food industry;<a href="#cite_note-81">[81]</a> therefore biofuels cannot be held solely responsible for this deforestation. There is a pressing need for sustainable palm oil production for the food and fuel industries; palm oil is used in a wide variety of food products. The Roundtable on Sustainable Biofuels is working to define criteria, standards and processes to promote sustainably produced biofuels.<a href="#cite_note-82">[82]</a> Palm oil is also used in the manufacture of detergents, and in electricity and heat generation both in Asia and around the world (the UK burns palm oil in coal-fired power stations to generate electricity). Significant area is likely to be dedicated to sugar cane in future years as demand for ethanol increases worldwide. The expansion of sugar cane plantations will place pressure on environmentally sensitive native ecosystems including rainforest in South America.<a href="#cite_note-83">[83]</a> In forest ecosystems, these effects themselves will undermine the climate benefits of alternative fuels, in addition to representing a major threat to global biodiversity.<a href="#cite_note-84">[84]</a> Although biofuels are generally considered to improve net carbon output, biodiesel and other fuels do produce local air pollution, including <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Nitrogen_oxide" title="Nitrogen oxide">nitrogen oxides</a>, the principal cause of <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Smog" title="Smog">smog</a>.[<a href="/web/20150305184539/http://en.wikipedia.org/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed">citation needed</a>] <h2>Politics[<a href="/web/20150305184539/http://en.wikipedia.org/w/index.php?title=Issues_relating_to_biofuels&action=edit&section=17" title="Edit section: Politics">edit</a>]</h2> <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Steven_Rattner" title="Steven Rattner">Steven Rattner</a>, former "auto czar" for <a href="/web/20150305184539/http://en.wikipedia.org/wiki/U.S._President" title="U.S. President" class="mw-redirect">U.S. President</a> <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Barack_Obama" title="Barack Obama">Barack Obama</a>, wrote an <a href="/web/20150305184539/http://en.wikipedia.org/wiki/Op-ed" title="Op-ed">Op-ed</a> for The New York Times in June, 2011, entitled "The Great Corn Con," characterizing ethanol as "an example of government policy run amok."

After mapping rigorous regulations for cleaner fuels in 2009, the European Commission decided not to set specific fuel targets from 2020 to 2030. Instead the Commission recommended <a href="#cite_note-87">[87]</a> a “more holistic and integrated approach” to creating an efficient biofuels policy. The EC also called for “an improved biomass policy” to “maximize the resource efficient use of biomass in order to deliver robust and verifiable greenhouse gas savings and to allow for fair competition between the various uses of biomass resources in the construction sector, paper and pulp industries and biochemical and energy production.” Fair competition in the acquisition of biomass feedstocks is what established bio-industries are asking for. Incentives provided to biofuel producers create an uneven playing field. “The pine chemical industry, which uses a co product called crude tall oil from the paper-pulping process, says it's concerned that incentives will divert its major raw material into biofuel production,” stated a Greenwire article.<a href="#cite_note-88">[88]</a> <h2>See also[<a href="/web/20150305184539/http://en.wikipedia.org/w/index.php?title=Issues_relating_to_biofuels&action=edit&section=18" title="Edit section: See also">edit</a>]</h2> <ul> <li><a href="/web/20150305184539/http://en.wikipedia.org/wiki/Environmental_impact_of_aviation" title="Environmental impact of aviation">Environmental impact of aviation</a></li> <li><a href="/web/20150305184539/http://en.wikipedia.org/wiki/Social_and_environmental_impact_of_palm_oil" title="Social and environmental impact of palm oil">Social and environmental impact of palm oil</a></li> <li><a href="/web/20150305184539/http://en.wikipedia.org/wiki/Environmental_issues_with_energy" title="Environmental issues with energy" class="mw-redirect">Environmental issues with energy</a></li> <li><a href="/web/20150305184539/http://en.wikipedia.org/wiki/List_of_environmental_issues" title="List of environmental issues">List of environmental issues</a></li> </ul> <h2>References[<a href="/web/20150305184539/http://en.wikipedia.org/w/index.php?title=Issues_relating_to_biofuels&action=edit&section=19" title="Edit section: References">edit</a>]</h2> <div class="reflist columns references-column-count references-column-count-3" style="-moz-column-count: 3; -webkit-column-count: 3; column-count: 3; list-style-type: decimal;"> <ol class="references"> <li id="cite_note-1"><a href="#cite_ref-1">^</a> <a rel="nofollow" class="external text" href="https://web.archive.org/web/20150305184539/http://www.unep.org/resourcepanel/Publications/tabid/54044/Default.aspx">Towards sustainable production and use of resources: Assessing Biofuels</a>, 2009, <a href="/web/20150305184539/http://en.wikipedia.org/wiki/International_Resource_Panel" title="International Resource Panel">International Resource Panel</a>, <a href="/web/20150305184539/http://en.wikipedia.org/wiki/United_Nations_Environment_Programme" title="United Nations Environment Programme">United Nations Environment Programme</a></li> <li id="cite_note-IEA-2"><a href="#cite_ref-IEA_2-0">^</a> various (2006). <a rel="nofollow" class="external text" href="https://web.archive.org/web/20150305184539/http://www.iea.org/publications/freepublications/publication/weo2006.pdf">World Energy Outlook 2006</a>.

A good ethanol yield is about 480 gallons per acre per year, and a typical corn yield is 5.6 tons per acre per year. Assuming that half the crop water needs can be met through rainfall, this would mean that still 1,570 cubic meter (1.57m liter) - 280 cubic meter of water per ton, multiplied by 5.6 tons per acre - of irrigation water are needed per acre per year to produce 1,817 liter (480 gallons) of ethanol.</li> <li id="cite_note-20"><a href="#cite_ref-20">^</a> The Economist, March 1, 2008, Ethanol and water: don't mix, p. 36</li> <li id="cite_note-21"><a href="#cite_ref-21">^</a> Barnett, Cynthia.
