Biochar
Trees in Hard Landscapes, A Guide for Delivery, published by the Trees and Design Action Group in September 2014, suggests that biochar is: ‘…the name for charcoal when it is used as a soil amendment.’
Keeping 1.5°C Alive: Closing the Gap in the 2020s, version 1.0, published by the Energy Transitions Commission in September 2021, defines Biochar as: “The thermal decomposition of biomass in the absence of oxygen forms a charcoal known as biochar. This can be added to soils to improve soil fertility and to act as a stable long-term store of carbon.” (Definition from UK Committee on Climate Change (2018), Biomass in a low-carbon economy.)
