Summary/Abstract
The prospect of global scale biochar application to soils highlights the importance of a sophisticated and rigorous certification procedure. This paper proposes that a sustainability framework for biochar could be adapted from existing frameworks developed for bioenergy. Sustainable land use policies, combined with effective regulation of biochar production facilities and incentives for efficient utilization of energy, and improved knowledge of biochar impacts on ecosystem health and productivity could provide a strong framework for the development of a robust sustainable biochar industry. The objective of this work is to discuss the concept of integrating biochar properties with environmental factors and with a sustainable biochar certification procedure.
