Investing in the present for our future

30+ Years

The Global Sustainable Equity Team share a simple yet ambitious mission: to deliver outstanding investment returns to clients; to be leaders in sustainable investing; and, as active managers, to play a part in making the world a better place.

Investing with intentionality

We seek to intentionally identify companies which have a positive impact while avoiding those that do harm. As such, we invest in companies with resilience and compounding growth characteristics that seek to address environmental and social change. As co-signatories of the Net Zero Carbon 20 initiative, we are fully committed to delivering a low carbon strategy in line with carbon-neutrality targets.

Committed to a consistent, repeatable process

The four pillars of our sustainable investment approach remain as pertinent today as they did three decades ago while the advancement of sustainable knowledge has continually shaped our investment approach. Overall, the strategy remains rooted in its core beliefs.


A transparent approach to leading sustainable investing

Our proprietary methodology to align each portfolio company to the UN Sustainable Development Goals is one of the first investment methods formally recognised by the UN. As leaders in sustainable investing, we share our success.
