Assets under management in the impact and ESG space are close to an all-time high, somewhere between $1.5 and $1.6 trillion. So why is capital actually leaving the sector? In this episode of the State of Sustainability, host Saif Hameed takes a detour from resilience and volatility to dig into what's going wrong, and where the genuine opportunities still exist.

The short answer: the industry has an identity problem. ESG labels get applied to mainstream tech stocks on the basis that they carry low environmental risk. Returns across impact funds are wildly inconsistent and the gap between what the sector promises and what it can actually deliver has become impossible to ignore.

Saif traces how impact investing developed along two tracks. Private markets had early pioneers like the Acumen Fund building something genuinely mission-led. Public markets then borrowed the language through ESG frameworks, with rather looser results.

Three lessons from that history:
ESG was never designed to do this job. It emerged in the 1990s as a risk-assessment tool, not as a valid basis for investment inclusion. Retrofitting it into a mainstream strategy was always going to cause problems.

The trade-off question needs an honest answer. You cannot simultaneously maximise financial returns and social impact without giving something up. The industry has spent years avoiding that conversation.

Measurement doesn't scale. Comparing affordable housing projects with renewable energy infrastructure under a single performance framework produces numbers that mean very little.

Where does that leave things? Saif argues the sector needs a significant rebrand and a serious recalibration of financial expectations. But there are three areas where impact investing still has real potential: generating brand equity and strategic value for corporate venture capital; venture philanthropy, where charitable capital gets recycled for compounding impact rather than disappearing into operational costs; and catalytic first-loss capital inside blended finance structures run by multilateral development institutions.

The through-line: accepting below-market returns might be the only way to preserve what impact investing was actually supposed to be.
