Jingzheng Ren is Assistant Professor of Modelling for Energy, Environment and Sustainability at the Department of Industrial and Systems Engineering of Hong Kong Polytechnic University (PolyU). He has also been nominated as adjunct/honorary associate professor of University of Southern Denmark (Denmark) and associated senior research fellow of the Institute for Security & Development Policy (Stockholm, Sweden). Prof. Ren serves as board member of several scientific journals and published more than 150 papers, authored 1 book, edited more than 10 books and published more than 40 book chapters. His research focuses on process system engineering for better sustainability and mathematical models for solving energy and environmental problems and promoting sustainability transition Antonio Scipioni, University of Padova. Professor at the Industrial Engineering Department. He is the Director of CESQA, a leading research group with outstanding research results in the field of environmental and energy management. He is the member of the national committee on environment that approve standards on environmental management issues. He has managed as scientific director several European funded projects for the University of Padova with partners from all over Europe and with a specific focus on Energy issues and sustainability. Alessandro Manzardo is a senior associate researcher in the field of footprint and sustainability assessment in the Department of Industrial Engineering at the University of Padova. He is the chair of the Italian committee at the ISO/TC 207 committee on ISO standards related to environment. He is an active member in several UNEP-Life Cycle Initiative processes on the definition of Life Cycle Assessment and Sustainability methods (e.g. Footprints). He has scored several papers on energy-related topics with specific focus on Hydrogen Energy. Hanwei Liang is an assistant professor in the Collaborative Innovation Center on Forecast and Evaluation of Meteorological Disaster, School of Geography and Remote Sensing, Nanjing University of Information Science & Technology. She obtained her Ph.D. in Engineering from Nagoya University in 2014. Her research mainly focuses on civil engineering and applications of operations research for sustainability.
