Can we use plants to draw carbon dioxide from the atmosphere and then lock it away in forms that will prevent it being re-released? Biochar and afforestation are two related geoengineering techniques that aim to draw carbon dioxide out of the atmosphere by growing biomass and storing it by converting it into a charcoal (biochar) or allowing the amount of biomass to accumulate (afforestation). This seminar involved three panelists who made brief presentations on the science of biochar, the climatological impacts of large-scale afforestation, and potential side-effects of large scale implementation of biochar as a means of carbon sequestration. These presentations were followed by a question and answer period with the audience and discussion amongst the participants.
This event was part of a seminar series: “The science, governance and ethics of climate intervention techniques.”
