Abstract: The estimations of land use changes and greenhouse gas emissions induced by biofuels remain highly controversial. After some first estimates in 2009, the California Air Resource Board releases new estimates in 2014. This paper explains two striking new results. First, the absolute reduction in the estimate of average US soya biodiesel is much greater than the reduction in the estimate of average US corn ethanol (by respectively 33 and 10g CO2eq/MJ). According to the new estimates, these two biofuels now induce more similar greenhouse gas emissions. Second, the newly reported EU and US canola biodiesel estimates are very different (respectively greater than 35 and 10g CO2eq/MJ).
