The National University of Singapore’s Lee Kuan Yew School of Public Policy (LKYSPP) has formally launched a time pressing initiative to build its Institute on Environment and Sustainability (IES). The mission is to create Southeast Asia’s leading think tank for generating “fit for purpose” sustainability policy analysis, skills, and thought leadership. It is devoted to helping governments and private sector “close the gap” between policy tools and desired outcomes in Singapore, ASEAN and Asia. We will tackle the region’s most pressing climate, environment, and sustainability challenges by helping to identify, design and trigger effective sustainability policy pathways.
