ANG Beng Wah

Biography

ANG Beng Wah (B.W. Ang) is Emeritus Professor at the Department of Industrial Systems Engineering and Management (ISEM), National University of Singapore (NUS). He specializes in energy, climate change and sustainability. More recently, his focuses are on energy transition, deep decarbonization, net-zero emissions and green economy.

He proposed the logarithmic mean Divisia index (LMDI) decomposition technique, which has been widely used by researchers, national agencies and international organizations to study factors affecting national energy consumption and carbon emissions, as well as to monitor sectoral and economy-wide energy efficiency trends.

He is a Co-Editor of Energy Economics, and a member of the editorial boards of several other international academic journals including Energy Policy, Energy, and Economics of Disasters and Climate Change. He has consistently been named a highly cited researcher by Clarivate Analytics and in other citation analysis sources.

He received his BSc from the then Nanyang University and PhD from the University of Cambridge, respectively in 1977 and 1981. Before joining NUS, and from 1981 to 1983, he was a post-doctoral researcher in the Energy Research Group at the Cavendish Laboratory of the University of Cambridge. He has previously served as Head of the ISEM Department and Executive Director of the Energy Studies Institute, NUS.
