Impact investing, which counts a variety of causes among its beneficiaries, is much harder to quantify, compared with carbon accounting. According to panellists at the seventh annual Global Research Alliance for Sustainable Finance and Investment (GRASFI) conference on 2 September at SMU, there is currently no perfect solution. Koh Lin-Net, institutional relations lead at Temasek Trust hoped the academic community could help the sector collect the data cost-effectively using technology. The moderator of the panel was SMU Associate Professor of Finance and Co-Director of Singapore Green Finance Centre Liang Hao. It is the first time GRASFI convened in person in Asia between 2 and 4 September 2024.
