New Studies Support Cellulosic Ethanol

A team of researchers led by Jason Hill and David Tilman at the University of Minnesota have published an interesting assessment of the health costs of both greenhouse gas and fine particulate matter from corn ethanol, gasoline and cellulosic ethanol. The study is available in the Proceedings of the National Academy of Sciences early release for Feb. 10. The conclusion is favorable to cellulosic ethanol: The benefits of shifting from gasoline and the current generation Read More >

Biofuels and Irreversible Climate Change

Last week, the paper Irreversible climate change because of carbon dioxide emissions was published in the early edition of the Proceedings of the National Academy of Sciences. The article received coverage on the airwaves, blogosphere, and in the traditional media. Susan Solomon, the lead author on the paper was interviewed by NPR, “We’re used to thinking about pollution problems as things that we can fix,” Solomon says. “Smog, we just cut back and everything will Read More >

I Say Sustainable, You Say…

The Guardian newspaper reported last week that environmental activist and reporter George Monbiot had successfully petitioned Britain’s Advertising Standards Authority (ASA) to ban an ad containing the tagline, “Biofuels — A Lower-Priced, Sustainable Answer to OPEC’s Oil.” The ad was sponsored by the Renewable Fuels Association, the Canadian Renewable Fuels Association, the European Bioethanol Fuel Association, and the Brazilian Sugarcane Industry Association. Though Monbiot’s petition is not publicly available, the ASA’s adjudication response indicates it Read More >

Comparing Energy Sources

Stanford University Professor Mark Z. Jacobson recently published a new paper in the journal Energy & Environmental Science, “Review of solutions to global warming, air pollution, and energy security.” According to Stanford News Writer Louis Bergeron, Jacobson has conducted the first quantitative, scientific evaluation of the proposed, major, energy-related solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water Read More >

Europe to Study Indirect Land Use

The European Parliament on Dec. 17 adopted amendments to the Renewable Energy Sources Directive, raising targets for production of biofuels but at the same time setting strict sustainability standards to monitor and reduce greenhouse gas emissions from the use of road transport fuels. The Parliament’s adopted text makes clear that it intends to calculate climate change emissions from international land use, but that the science is not currently available to do so: Whereas (11) In Read More >
