Sustainable Consumption and Production

Policy Researcher

Ryu Koide is a policy researcher at the Institute for Global Environmental Strategies (IGES), focusing on policy analysis and data science of sustainable consumption and production (SCP) and low-carbon lifestyles. With his background in resources and environmental engineering, public policy, and statistical analysis, Koide places emphasis on interdisciplinary research analysing consumer lifestyles and evaluating policies and projects for facilitating the transition towards sustainable societies.　
His recent research work includes identifying opportunities for low-carbon lifestyles through life cycle assessment, downscaling planetary boundaries into consumption-based targets, analysing carbon footprints of consumer segments using expenditure survey microdata, developing impact and scalability assessment framework of sustainability projects, and assessing national policy integration of sustainable consumption and production. Before joining IGES, Koide served as a consulting engineer specialised in environmental management in Asia, Africa, and South America with a strong emphasis on capacity building of local and national governments.
