A lack of trustworthy sustainability data is dampening investor interest in India, according to a new report by Deloitte and the Fletcher School at Tufts University. The study, titled "Investor Trust in Sustainability Data," highlights that 78 percent of institutional investors in India allocate up to 30 percent of their funds to organisations with clearly defined and measurable Environmental, Social, and Governance (ESG) objectives. However, the scarcity of credible data is becoming a significant barrier to sustainable investment.
