Climate saviour or climate endgame?
Almuth Ernsting and Deepak Rughani, Updated December 2008
This is a critical analysis of proposals for 'carbon negative' bioenergy, including biochar (agrichar) and bioenergy with carbon capture and storage, as a means of reducing atmospheric carbon dioxide concentrations and mitigating climate change. It includes a wider discussion about the impacts of large-scale bioenergy, and about alternative adequate responses to the current crisis.
