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...

The possibility of encouraging the growth of forests as a means of sequestering carbon dioxide has received considerable attention because of concerns about the threat of global climate change due to the greenhouse effect. Would this approach be as inexpensive as studies have suggested? We...

The total expected cost of sequestering carbon in agricultural soils is estimated under different government-based and market-based policies. A possible government-based EQIP programme offering a per-acre subsidy to adopt conservation tillage and a market-based carbon credit programme where...
