Equities and bonds

Creating positive impact through public equities and bonds, with a long-term horizon

Seasoned first mover with longstanding track record

As one of the first pioneers to offer dedicated impact strategies through listed assets, we know what we are doing. Over the last 25 years we have developed a systematic and successful investment approach. Our robust track record speaks for itself. We apply a forward-looking lens, focusing on the ambition and capacity of companies to drive transformative change within their respective sectors.

Industry-leading impact investment analysis

Integrated financial and sustainability analysis is at the heart of our selection process. We determine the valuation of companies both from an inside-out (impact on people and planet) and from an outside-in (risks and opportunities) perspective. Our selection process is guided by our Minimum Standards: a very strict set of exclusion criteria to ensure that all forms of harmful activities are excluded.

Active stewardship

Stewardship is an integral part of our investment management process, with engagement, voting and advocacy as the key pillars. From the moment company analysis begins, we have ongoing one-on-one conversations with companies to discuss sustainability topics. We do this both by following a formal engagement agenda and on an ad hoc or event-driven basis. View our Stewardship page.
