UK Study Highlights Uncertainty in Calculating Indirect Land Use Emissions

Britain’s Renewable Fuels Agency this week released the Gallagher Review, a report on the indirect effects of biofuels production that was prompted by the Searchinger and Fargione studies published in Science earlier this year. (See this blog’s earlier post on the forthcoming study.) The summary of the conclusions of the Gallagher Review include some very telling comments: Quantification of GHG emissions from indirect land-use change requires subjective assumptions and contains considerable uncertainty. “Current lifecycle analyses Read More >

Questioning the Relationship Between Biofuels and Food Costs

A new study released by Texas A&M’s Agricultural and Food Policy Center undermines one of the key assumptions used in the studies that attributed a huge “carbon debt” to biofuels. The assumption used by Searchinger et al. is that biofuel production increases the cost of all commodity grains, encouraging countries to convert additional land – such as rainforest, peat land, and savannah – to agricultural production. The Searchinger paper calculates that agricultural production will have Read More >

British Government to Study Indirect Impacts of Biofuels

Last week, Britain’s Renewable Fuels Agency (RFA) launched a series of studies of the indirect land-use impacts of biofuels, following a lecture by Princeton’s Tim Searchinger, lead author of “Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land Use Change” published in Science in February. The RFA intends to publish a draft report in May, prior to negotiation of EU-wide biofuels targets to 2020 in Brussels later this year. Britain is set Read More >

Indirect Land Use Thoughts

Dear Colleagues: I have spent a lot of time the last few weeks trying to think through the indirect land use change (ILUC) issue. I have divided my thoughts into two questions that I am asking myself: 1) are we in fact currently able to estimate these changes with any degree of confidence?, and 2) if we could estimate such changes, would it be a good idea to base policy on those estimates? My current Read More >
