Sustainability assessment of biochar : evaluating the potential environmental, economic and social impacts of the production and application of biochar in Europe as an option for climate change mitigation
description Sustainable development and climate change are at the forefront of today’s political agendas, as signified by the 2016 Paris Agreement and the 2015 United Nations’ Sustainable Development Goals.
