Biochar is a greenhouse gas removal (GGR) technology that can potentially make a major contribution to the UK’s net zero target achieving greenhouse gas emission reductions when applied to agricultural lands, peatlands and other locations. However, the big questions are: how can we make sure it is environmentally sustainable and economically viable? And are there any technological improvements that can facilitate the realisation of these goals?

Human greenhouse gas emissions are the root cause of climate change, affecting the Earth’s natural equilibrium. The effects of climate change are likely to include temperature rise, sea level rise, ocean acidification, and increased frequency and severity of extreme weather events (e.g., drought and flooding),…
