| 原文摘要 | This paper describes a technology (biochar sequestration) that can meet the challenges of global climate change by reducing greenhouse gas emission from fossil fuels. When combined with bionergy production, this biochar sequestration is a clean energy technology that reduces emissions as well as sequesters carbon. It also locks up rapidly decomposing carbon in plant biomass in a much more durable form. The various advantages of this technology in terms of storage capacity, emission reduction, pollution control, and ease of monitoring are discussed. In addition, biochar sequestration does not require a fundamental scientific advance and the underlying technology is robust and simple. It does, however, require studies to optimize biochar properties and to evaluate the economic costs and benefits of large-scale deployment. |
