Biofuels not as ‘green’ as many think
Go back to basics when calculating the greenhouse impact and carbon neutrality of biofuels, researchers urge
Statements about biofuels being carbon neutral should be taken with a grain of salt. This is according to researchers at the University of Michigan Energy Institute after completing a retrospective, national-scale evaluation of the environmental effect of substituting petroleum fuels with biofuels in the US. America’s biofuel use to date has in fact led to a net increase in carbon dioxide emissions, says lead author John DeCicco in Springer’s journal Climatic Change.
