Yasushi Kondo

Professor Yasushi Kondo of Waseda University's School of Political Science and Economics is a leading expert in environmental economics and industrial ecology. Holding a PhD in Economics from the University of Tsukuba, he has pioneered input-output analysis methodologies for material flow assessment, carbon footprint quantification, and circular economy modeling.

• Key research themes: Industrial ecology, input-output economics, sustainable resource management
• Major contributions: Development of MaTrace model for material tracking, waste input-output analysis frameworks, and dynamic recycling optimization
• Scientific recognition: Sir Richard Stone Prize (2018), ILCAJ Outstanding Achievement Award (2019), multiple journal awards

His work on tracking global metal cycles, PM2.5 pollution footprints, and economic drivers of material flows has reshaped sustainability policy analysis through data-driven supply chain mapping and consumer responsibility frameworks.

• Notable findings:
  • Quantified 2M+ premature deaths from G20 consumption patterns
  • Demonstrated 94-98% recovery potential for alloying elements through improved scrap sorting
  • Identified trade-offs between steel quality and regional material cycle closure

Professor Kondo's research combines rigorous mathematical modeling with actionable policy recommendations, particularly through his affiliations with international organizations like the International Input-Output Association and the International Society for Industrial Ecology.
