Investors are increasingly integrating environmental, social, and governance (ESG) issues into their investment decisions. Currently, more than half of managed assets in Europe are linked to ESG factors, while in Japan, ESG investment has grown dramatically in recent years.In principle, ESG investment can help to bridge the gap between profit-driven investment and economic and social sustainability in Asia and the Pacific. However, a number of challenges, such as unclear and varied sustainable investment criteria, untested impacts on corporate value and social issues, and the lack of quality data cloud the potential for increasing ESG investment. This book aims to contribute to developing a framework for future analysis and monitoring to ensure the growth of ESG investment.
