A recent survey found that, although institutional investors are driving hedge fund managers to embrace sustainable investing, many challenges remain, including inadequate data; shortage of expertise; lack of consensus on definitions and standards; and greenwashing problems. The survey report (Report) was a joint effort by the Alternative Investment Management Association (AIMA), KPMG International, CREATE-Research and the Chartered Alternative Investment Analyst Association. This article discusses the key takeaways from the Report.
