Carbon mitigation is a term denoting strategies/technologies to decrease anthropogenic carbon dioxide emissions. Carbon mitigation can be achieved by direct capture of CO₂ from the air by industrial means, or by biomass-based methods. Some biomass-based methods (like biomass-CCS or biomass with carbon capture and storage) have the potential for “carbon-negative emissions”. An article by James S. Rhodes and David W. Keith in a recent issue of the open access journal, Climate Change, gives some insights on biomass-CCS, and its possible impacts on biomass-based mitigation.
