Findings have major implications for climate change policy
Turning native ecosystems into “farms” for biofuel crops causes major carbon emissions that worsen the global warming that biofuels are meant to mitigate, according to a new study by the University of Minnesota and the Nature Conservancy.
High oil prices, energy security considerations and fears about global warming have helped revive interest in renewable energy sources like biofuels, which burn cleanly and can be produced from plants.
