The lion’s share (88%) of PSI signatories observed have developed policies designed to help them incorporate sustainability considerations into investment decision-making, compared with just over half (55%) of non-signatories. Seventy-one percent of signatories have published policies governing engagement or proxy voting on sustainability issues, compared with 35% of non-signatories, the analysis finds.

Taken together, the findings suggest that PSI signatories have tended to integrate sustainability earlier and more systematically than non-signatory peers, with a tighter tie between risk-management practices and long-term business planning.
