We assessed agricultural bioenergy pathways using existing and newly developed life cycle energy analyses so as to compare the potential of these pathways to replace fossil fuel in Canada. Energy gains after subtracting life cycle fossil energy inputs ...

Many pathways have been proposed for including land use in a post-2012 climate agreement. Several involve new accounting structures which are quite different from the rules established in the Marrakech Accords and related decisions. However, a mechanis...

This paper presents a framework that encompasses a full range of options for including land use, land-use change, and forestry (LULUCF) within future agreements under the United Nations Convention on Climate Change (UNFCCC). The intent is to provide op...

At best, common renewable energy strategies can only offset fossil fuel emissions of CO2 - they cannot reverse climate change. One promising approach to lowering CO2 in the atmosphere while producing energy is biochar bio-energy, based on low-temperatu...

New and renewable fuels are the major alternatives to conventional fossil fuels. Biomass in the form of agricultural residues is becoming popular among new renewable energy sources, especially given its wide potential and abundant usage. Pyrolysis is t...
