Professor Beng Wah Ang is an Emeritus Professor at the Department of Industrial Systems Engineering and Management at the National University of Singapore, where he has established himself as a preeminent scholar in energy economics and systems analysis over a distinguished academic career. His foundational work bridges industrial engineering and economic modeling, creating robust analytical frameworks that have transformed how energy consumption and environmental impacts are measured and understood globally. Throughout his tenure at NUS, Professor Ang cultivated a research program that consistently addressed critical challenges in sustainable development, earning him international recognition as a thought leader in energy policy analysis. His transition to emeritus status represents the culmination of decades of scholarly excellence while maintaining active engagement in advancing the field through continued publication and mentorship.
Professor Ang's pioneering development of the Logarithmic Mean Divisia Index method has revolutionized decomposition analysis in energy economics, providing researchers and policymakers with a rigorous mathematical framework to quantify driving factors behind energy intensity and carbon emission changes across sectors and regions. This seminal contribution, now considered the standard methodology in the field, has enabled precise attribution of economic and structural factors influencing energy consumption patterns, directly informing national and international climate policy decisions. With his publications accumulating over 38,000 citations, his methodological innovations have been formally adopted by major international organizations including the International Energy Agency and the Intergovernmental Panel on Climate Change for their analytical protocols. The global implementation of his approaches across more than 50 countries demonstrates the exceptional versatility and scientific rigor of his frameworks in diverse economic and energy system contexts.
Beyond his technical contributions, Professor Ang has profoundly shaped the energy economics community through extensive mentorship of doctoral students and early-career researchers who now lead critical initiatives in academia, government agencies, and international organizations worldwide. His editorial leadership of leading energy economics journals and participation in high-level advisory panels for Asian development institutions have significantly influenced research directions and policy frameworks across the Asia-Pacific region. Even in emeritus status, his work continues to underpin cutting-edge research on sustainable energy transitions and decarbonization strategies, with his methodologies being continuously adapted to address emerging challenges in renewable energy integration and circular economy systems. Professor Ang's enduring legacy lies in establishing the analytical bedrock upon which contemporary energy policy formulation and climate mitigation efforts are systematically constructed.
