Biochar is a carbon-rich solid obtained from the heating of biomass in the (near) absence of oxygen in a process called pyrolysis. Its soil incorporation is increasingly discussed as a means to sequester carbon in soils and, thus, to help mitigate climate change. When deployed in agricultural...

Biochar is a carbon-rich solid obtained from the heating of biomass in the (near) absence of oxygen in a process called pyrolysis. Its deployment in soils is increasingly discussed as a promising means to sequester carbon in soils and, thus, to help mitigate climate change. For a wide range of...

This note synthesises the available literature examining the impact of agricultural support on greenhouse gas (GHG) emissions as well as its impact on water, biodiversity, and land. In keeping with the Secretariat's impartiality, the note reports the findings as they appear in the literature....
