Prospective Assessment of the Carbon Footprint of a National Power Generation System -- Energy Valorisation of Bio-glycerol: Carbon Footprint of Co-pyrolysis Process of Crude Glycerol in a CHP Plant -- Decarbonisation of Electricity Generation: Efforts and Challenges -- Carbon Footprint of Brazilian Highway Network.This book presents revealing case studies on carbon footprint calculation and mitigation in various industrial sectors. There are numerous sectors whose carbon footprints need to be calculated, and effective ways to mitigate the greenhouse-gas emissions from these sectors need to be found. Using representative case studies, this book highlights the carbon footprint of national power generation systems, crude glycerol production plants and the Brazilian highway network system, as well as the integration of renewable energy sources in expansion planning, so as to promote and implement power system decarbonization.
