This white paper by Robeco’s quant research and sustainability team outlines a framework for integrating sustainability directly into portfolio optimization alongside risk and return.
A 3D optimization approach jointly targets return, risk, and sustainability, avoiding the hidden costs of constraint-based ESG integration.
Proprietary climate, biodiversity, and SDG metrics capture distinct, weakly correlated sustainability dimensions, enabling diversified impact.
Empirical results show material sustainability improvements can be achieved with modest increases in tracking error.
How might this framework reshape portfolio construction as investor sustainability preferences continue to evolve?
