2. Across the market, IMM practices have grown increasingly sophisticated as investors shift from building consensus for IMM to strengthening its integration within investment processes.
3. As the market grows and matures, impact investors increasingly demand insight into impact performance.
4. Impact measurement and management incurs some costs—yet also generates financial benefits.
