The connection to land use is discussed in many biofuel contexts. Using land for production of biofuels could lead to food production being moved, potentially affecting both food prices and green house gas emissions. Land use thus becomes an impact factor for climate performance of biofuels depending on where crops used for production are grown.
Calculating the impacts from direct land use change, DLUC, is possible, even if there are uncertainties in how results could be assessed. ILUC – indirect land use change – is however a far more complicated term.
f3 has a new fact sheet explainging the basis for the most recent research on ILUC and how it affects the performance of biofuels. The fact sheet is at this point only available in Swedish.
