Dirty Biofuels: Leaked Data Shows Some Worse Than Fossil Fuels
February 10, 2012 According to leaked data from the European Commission obtained by EuroActiv, greenhouse gas emissions from some biofuels are higher than those from fossil fuels, when Indirect Land Usage Change (ILUC) is factored in.
EuroActiv reports:
ILUC happens when forests and wetlands are cleared to compensate for lands taken to grow biofuels elsewhere.
One recent report predicted that all of Malaysia’s tropical peatswamp forests would be destroyed by the end of the decade because of ILUC - with alarming consequences for greenhouse gas emissions - unless the expansion of palm oil production was halted.
To measure the climate impact of fuels, Brussels favours assigning default values based on a calculation of their full lifecycle emissions, hence the debate over ILUC factors and biofuels.
In its recent review of the Fuel Quality Directive, the EU proposed a default value of 107g CO2 equivalent per megajoule of fuel (CO2/mj) for oil from tar sands, as compared to 87.5g CO2/mj for crude oil, reflecting the greater environmental harm that its production causes.
