Climate Geo-engineering with ‘Carbon Negative’ Bioenergy

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.  The statements and conclusions contained in the report are the sole responsibility of the authors.
