Unlike petroleum or coal, the soybeans, corn,switchgrass\u00a0and other biological materials that are made into biofuels are not dug up from underground, nor do they release long-stored carbon as carbon dioxide into the atmosphere when burned. Instead, when biofuels are burned, carbon dioxide they recently captured is release back into the atmosphere.<\/p>\n<div class=\"singleimage center\">\n<div class=\"thumb tright\">\n<div class=\"thumbinner\">\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-1856\" src=\"https:\/\/www.htoilmachine.com\/blog\/wp-content\/uploads\/2019\/01\/CarbonCycle-1.jpg\" alt=\"\" width=\"540\" height=\"417\" \/><\/p>\n<div class=\"thumbcaption\">This carbon cycle diagram shows the storage and annual exchange of carbon between the atmosphere, hydrosphere and geosphere in gigatons &#8211; or billions of tons &#8211; of carbon (GtC). Burning fossil fuels adds about 5.5 GtC of carbon per year into the atmosphere. Carbon released by burning biofuels is partly balanced by carbon fixed during biofuel feedstock growth.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p>&nbsp;<\/p>\n<p>This advantage has sometimes been exaggerated into the claim that <a href=\"https:\/\/www.htoilmachine.com\/pro\/biodiesel-technology-c-22\/\">biodiesel<\/a>, ethanol and other biofuels are\u00a0carbon neutral.Unfortunately, this is not always true. For example, fossil fuels that release carbon dioxide are used in farming, fertilizer production, transportation and many aspects of biofuel processing during the full life cycle of most biofuels.<\/p>\n<p>&nbsp;<\/p>\n<p><a id=\"Indirect_Land_Use_Impacts\" name=\"Indirect_Land_Use_Impacts_of_Biofuels\"><\/a><\/p>\n<h2><span class=\"mw-headline\">Indirect Land Use Impacts of Biofuels<\/span><\/h2>\n<p>Cropping changes, the conversion of forests into cropland and other\u00a0land-use\u00a0changes connected with the growing of biofuel crops all have greenhouse gas, and thus climate change implications. Worldwide land-use patterns can be affected by small variations in commodity prices, and these effects need to be considered in a full\u00a0life-cycle analysis.<\/p>\n<p>Two articles in the February 2008 issue of the journal\u00a0<i>Science<\/i>\u00a0called widespread attention to these so-called\u00a0indirect land use impacts\u00a0of biofuels. (See Fargione et al, 2008 and Searchinger et al, 2008.)<\/p>\n<p>The study of indirect land-use impacts is in its infancy, and predictions and measurements of these impacts are highly uncertain. Biotech companies and others have claimed that crop yield improvements will reduce greenhouse gas emissions by making farmland more productive, meeting the world\u2019s food and fuel needs with fewer acres, and reducing pressure to convert forests to farmland. In an ideal world this might all be true. But in the real world, land use change is driven by complex economic, social and political forces. Productivity is only one factor.<\/p>\n<p><a id=\"Differences_among_Biofuels\" name=\"Differences_among_Biofuels\"><\/a><\/p>\n<h2><span class=\"mw-headline\">Differences among Biofuels<\/span><\/h2>\n<p>Various efforts have begun to evaluate the sustainability of biofuel production systems. For example, some groups are working to create third-party\u00a0certification standards, reflecting a growing awareness that there are great differences among the greenhouse gas\u00a0footprints\u00a0and other environmental and social impacts of biofuels. In one extreme and widely publicized example, the clearing and burning of rainforests for\u00a0<a class=\"external_link\" href=\"https:\/\/www.htoilmachine.com\/pro\/palm-oil-processing-c-20\/\" rel=\"nofollow\">oil palm<\/a>\u00a0plantations in Indonesia is alleged to have caused enormous releases of carbon dioxide and other greenhouse gases as well as other serious environmental problems. At the other end of the spectrum, fuel made from waste vegetable oil or spoiled grain typically causes few concerns.<\/p>\n<p>Estimating the net effect of any given biofuel on atmospheric greenhouse gas levels or climate change requires extremely complicated calculations with many debatable assumptions. Many of the analyses to date have concluded that grain ethanol, biodiesel, and especially\u00a0cellulosic ethanol substantially reduce greenhouse gas emissions, in comparison to gasoline and diesel. Other researchers have called these results into question, however. (See, for example, Pimentel and Patzek, 2005.) Despite these different views, it is clear that biofuels are most likely to contribute to greenhouse gas reductions if they are produced with a minimum of fossil energy inputs and without significant land use changes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Can we reduce greenhouse gases with biofuels?
