Sustainable Equity

Our Sustainable Equity investment team looks for the leaders of tomorrow.

Generating returns from sustainable structural growth

The Sustainable Equity team invests in companies delivering solutions to the world’s environmental and social challenges. We focus on structural growth opportunities linked to sustainability: decarbonisation, climate adaptation, water, healthcare impact, financial and digital inclusion, and access to education.

Our investment approach blends proprietary sustainability insight, deep fundamental research, and high-conviction, benchmark-agnostic portfolio construction. Through active engagement and KPI-driven reporting, we aim to allocate capital to companies whose growth supports a more sustainable future.
