As sustainable development takes on an increasingly crucial role and governments adopt measures to mandate reduced carbon emissions, finding innovative means to render supply chains more eco-friendly represents a key goal in various industries. This book beings by focusing on CO2 emissions in a supply chain due to freight energy use and storage. It then continues to discuss a new perspective to graph-based total carbon footprint assessment of non-marginal technology-driven projects, and computational methods for estimation of life cycle carbon footprints of buildings.
