Carbon debt for some biofuels lasts centuries

(11/30/2011) It has long been known that biofuels release greenhouse gas emissions through land conversion like deforestation. But an innovative new study by the Center for International Forestry Research (CIFOR) published in Ecology and Society has computed how long it would take popular biofuel crops to payoff the "carbon debt" of land conversion. While there is no easy answer—it depends on the type of land converted and the productivity of the crop—the study did find that in general soy had the shortest carbon debt, though still decades-long, while palm oil grown on peatland had the longest on average.


Palm oil biofuel from peatlands has big climate impact, finds study

(11/08/2011) Biofuels produced from oil palm plantations established on tropical peatlands are a substantial source of greenhouse gas emissions, reports a comprehensive new assessment conducted for the International Council on Clean Transportation (ICCT).


Europe should lift duty on RSPO-certified palm oil to encourage use, says Dutch group

(09/21/2011) To encourage uptake of palm oil that is less damaging to the environment, the European Union (EU) should lift the import duty on palm oil certified under Roundtable on Sustainable Palm Oil (RSPO), said a Dutch industry group.


Greening the world with palm oil?

(01/26/2011) The commercial shows a typical office setting. A worker sits drearily at a desk, shredding papers and watching minutes tick by on the clock. When his break comes, he takes out a Nestle KitKat bar. As he tears into the package, the viewer, but not the office worker, notices something is amiss—what should be chocolate has been replaced by the dark hairy finger of an orangutan. With the jarring crunch of teeth breaking through bone, the worker bites into the “bar." Drops of blood fall on the keyboard and run down his face. His officemates stare, horrified. The advertisement cuts to a solitary tree standing amid a deforested landscape. A chainsaw whines. The message: Palm oil—an ingredient in many Nestle products—is killing orangutans by destroying their habitat, the rainforests of Borneo and Sumatra.


Greener palm oil arrives in the United States

(06/29/2010) The first shipment of palm oil certified under sustainability criteria have arrived in the United States, according to the Roundtable on Sustainable Palm Oil (RSPO).


Smart biofuels that don't hurt people or the environment are possible

(07/16/2009) Sustainable biofuels can be a reality but only in combination with reductions in fuel demand and increased productivity on existing agricultural lands, argue researchers writing in the journal Science. Five years ago biofuels were seen as a panacea for the world's energy hunger and the need to address climate change, but increased production of biofuels soon contributed to a clutch of problems, including competition with food, resulting in rising prices, and large-scale conversion of rainforests and tropical grasslands for feedstocks, resulting in biodiversity loss and increased greenhouse gas emissions. Environmentalists and scientists condemned many biofuels — including ethanol produced from Midwestern corn ethanol and biodiesel generated from European rapeseed and Southeast Asian palm oil — as a short-sighted energy solution. Some biofuels were found to be even worse for the environment, and more costly, than conventional gasoline. However some researchers remain optimistic that smart biofuel production could help meet energy demand without hurting people or the planet. In a Science Policy Forum piece, David Tilman and colleagues explore some of these options, noting that biofuels can be produced in substantial quantities at low environmental cost


Biofuels 200 times more expensive than forest conservation for global warming mitigation

(08/27/2008) The British government should end subsidies for biofuels and instead use the funds to slow destruction of rainforests and tropical peatlands argues a new report issued by a U.K.-based think tank. The study, titled "The Root of the Matter" and published by Policy Exchange, says that "avoided deforestation" would be a more cost-effective way to address climate change, since land use change generates more emissions than the entire global transport sector and offers ancillary benefits including important ecosystem services.


Biofuels can reduce emissions, but not when grown in place of rainforests

(07/22/2008) Biofuels meant to help alleviate greenhouse gas emissions may be in fact contributing to climate change when grown on converted tropical forest lands, warns a comprehensive study published earlier this month in the journal Environmental Research Letters. Analyzing the carbon debt for biofuel crops grown in ecosystems around the world, Holly Gibbs and colleagues report that "while expansion of biofuels into productive tropical ecosystems will always lead to net carbon emissions for decades to centuries... [expansion] into degraded or already cultivated land will provide almost immediate carbon savings." The results suggest that under the right conditions, biofuels could be part of the effort to reduce humanity's carbon footprint.


Biofuels are worsening global warming

(02/07/2008) Converting native ecosystems for production of biofuel feed stocks is worsening the greenhouse gas emissions they are intended to mitigate, reports a pair of studies published in the journal Science. The studies follow a series of reports that have linked ethanol and biodiesel production to increased carbon dioxide emissions, destruction of biodiverse forest and savanna habitats, and water and air pollution.


Palm oil is a net source of CO2 emissions when produced on peatlands

(12/17/2007) Researchers have confirmed that converting peat forests for oil palm plantations results in a large net release of carbon dioxide, indicating industry claims that palm oil helps fight climate change are unfounded, at least when plantations are established in peatlands.


Is the oil-palm industry using global warming to mislead the public?

(11/23/2007) Members of the Indonesian Palm Oil Commission are distributing materials that misrepresent the carbon balance of oil-palm plantations, according to accounts from people who have seen presentations by commission members. These officials are apparently arguing that oil-palm plantations store and sequester many times the amount of CO2 as natural forests, and therefore that converting forests for plantations is the best way to fight climate change. In making such claims, these Indonesian representatives evidently are ignoring data that show the opposite, putting the credibility of the oil-palm industry at risk, and undermining efforts to slow deforestation and rein in greenhouse gas emissions.
