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.
