Sustainable Biofuels

Bioenergy is included in many proposed strategies to reduce anthropogenic greenhouse gas emissions and limit the magnitude of global warming. Liquid biofuel production typically requires large areas of land for the production of feedstocks, resulting in a range of tradeoffs for the climate, local economies, and the environment. As part of the Great Lakes Bioenergy Research Center, we study current land use and land availability for next generation biofuels and bioproducts to understand the production potential and environmental outcomes of bioenergy production and how it could contribute to climate and conservation goals.
