Immediate action required »
Immediate action required
Immediate action required☜The scale and likelihood of the anticipatable consequences of climate change demand immediate action on climate change by society. Humanity should act immediately to avoid or minimise the climate changes and impacts that are avoidable, and prepare to adapt to those that are not.☜59C6EF

can be made from agricultural waste
can be made from agricultural waste☜There is no need for new cultures to produce biochar, since existing cultures produce plenty organic waste material, such as corn stalks. These simply need to be converted to biochar and buried in the soil.☜98CE71

can produce energy as side effect
can produce energy as side effect☜The preparation of biochar from organic material (through pyrolysis) can produce fuel (syngas and bio-oil) as a side product☜98CE71

can remove huge amounts of CO2 »
can remove huge amounts of CO2
can remove huge amounts of CO2☜systematic burying of biochar produced from all the agricultural waste produced in the world would remove so much carbon dioxide from the atmosphere that it would offset the CO2 produced by fossil fuel☜98CE71

improves the fertility of the soil »
improves the fertility of the soil
improves the fertility of the soil☜more experiments need to be done, but at least in some circumstances, e.g. in the Amazon rain forest, soils to which biochar has been added seem to be much more fertile☜98CE71

Monocultures harm biodiversity »
Monocultures harm biodiversity
Monocultures harm biodiversity☜At the scale required to sequester significant quantities of carbon, biochar production would necessitate additional land take from wild habitats, promote monocultures and harm biodiversity.☜EF597B

Virtually untested »
Virtually untested
Virtually untested☜The dynamics of the interaction of adding charcoal soil is very poorly understood and almost untested.☜EF597B
