UK Department for Transport (DfT) publishes paper on regional level actions to avoid ILUC

2011.06.24
Results of a study by Ecometrica/E4tech on possible regional level iLUC avoidance actions. Includes case studies of SE Asian palm oil and European OSR/wheat. The focus is on regional approaches to yield improvement and waste reduction. The paper stops short of trying to define policy approaches, and implementation would require addressing potential baseline/additionality issues.

The IEA, 27% biofuels and the cost of indirect land use change

2011.06.07
A few weeks ago, the IEA published a roadmap for biofuels in transportation. This argues that 27% of transport energy needs worldwide could be met with biofuels by 2050, saving a cumulative 20 billion tonnes (Gt) of carbon dioxide emissions over the next 40 years – all without affecting food security. The headline messaging for the report has been broadly represented (domesticfuel.com, thebioenergysite.com, thelowcvp.org.uk) as a call for continuation and expansion of existing biofuel mandates. By 2050, the roadmap assumes 32 exajoules of biofuel production, split 50:50 between crop-based and waste-based fuels, and that the crops will require 70 million hectares (Mha) of land to grow.

Michigan iLUC study (Kim and Dale) revisits iLUC baseline questions

2011.05.26
Kim and Dale in ‘Biomass and Bioenergy’ propose a no-iLUC conclusion by asserting that iLUC cannot have happened in any region where overall arable area is shrinking. Many in the field would dispute this interpretation.
