Two new studies have been released recently in peer-reviewed scientific journals, shedding more light on the carbon footprint of biofuels.
“Biofuels,
Land Use Change, and GHG Emissions: Some Unexplored Variables”, published
in Environmental Science and Technology,
studied “indirect land use change” and finds that “there are no real data on
what actually happens as demand increases for land for biofuel production in
one part of the world and potentially leads to land clearing, because it is
impossible to track these relationships in the real world.”
“Improvements in Life
Cycle Energy Efficiency and Greenhouse Gas Emissions of Corn Ethanol”, published in Journal of Industrial Ecology, finds
that the lifecycle GHG emissions of modern corn-based ethanol production are on
average 51 percent lower than that of gasoline.
