UN review favors sugarcane over corn

By | December 09, 2009
The United Nations has released an overview of recent major research reviews of first-generation biofuels from experts around the world. The UN report highlights a wide variety of issues related to global biofuels production, including current trends, environmental impacts and the potential impacts of increased demand and land use change.

The report stated that net greenhouse gas (GHG) savings resulting from emissions associated with biofuels production vary depending on feedstock used, conversion technology and methodological assumptions. Sugarcane was found to have the highest GHG savings, ranging from 70 percent to more than 100 percent when compared to emissions from fossil fuels. Comparatively, emissions from corn ethanol were found to have a savings of 60 percent to a 5 percent increase in emissions over fossil fuels.
