The Impax Sustainability Centre acts as our centre of excellence providing knowledge, tools and expertise on investing in the transition to a more sustainable economy to Impax and our clients. This allows Impax to meet the growing expectations of clients, regulators and other stakeholders. It also enables us to maintain our strong position in dealing with the rapidly expanding range and depth of sustainability issues.
The Impax Sustainability Centre is led by Co-Heads Lisa Beauvilain (Global Head of Sustainability & Stewardship) and Chris Dodwell (Global Head of Policy & Advocacy) who share management responsibilities and report directly into Impax’s Chief Executive, Ian Simm.
The Impax Sustainability Centre has four key areas of focus, as outlined below.

Investment sustainability & stewardship
Sustainability is fully integrated within Impax’s investment process. The Impax Sustainability Centre provides leadership, advice and oversight of investment-related sustainability research, thematic and sustainable universe development, impact measurement, development of proprietary tools and methodologies, management of Corporate and Issuer Resilience Analysis and processes*, and stewardship work including proxy voting and company-specific and thematic engagement, as well as policy insights for the investment process.
Advocacy & outreach
We aim to support policy makers who are working to create enabling environments that will accelerate the transition to a more sustainable economy. We are active across a range of channels, from traditional reactive approaches such as working through industry associations, responding to consultations, and participating in issue-specific initiatives and sign-on letters – to more innovative pro-active interventions such as publishing Impax’s perspectives and commentaries, funding research, piloting new approaches, partnering with clients, and bilateral discussions with policy makers. Impax’s efforts around “systematic stewardship” fall under this area of focus. Systematic stewardship combines company thematic engagement and policy advocacy as levers for accelerated change.
Thought leadership
Impax’s thought leadership and insights supports our investment process, as well as our clients and the industry at large. The Impax Sustainability Centre’s thought leadership provides Impax’s house view on important and evolving topics, supports research partnerships with academia and clients, and provides Impax’s firm-wide sustainability training and development.
Sustainability client advisory & reporting
The Impax Sustainability Centre also advises on sustainability in Impax’s product development, sustainable finance regulatory responses and reporting including the metrics and methodologies used to create Impax’s firm wide and client specific sustainability reporting. The Sustainability Centre also develops Impax’s firm-wide sustainability policies and is responsible for providing sustainability reporting expertise and insights to Impax’s clients.

Impax exercises its proxy voting rights and conducts its global stewardship activities on an independent basis on behalf and in the best interests of its clients, in accordance with Impax investment policies regarding good corporate governance applicable for all investee companies and not to foster a control transaction for any particular company. The application of these policies is predicated on the acquisition and ownership of securities in the ordinary course of business and were and are not acquired or held for the purpose of and do not have the effect of changing or influencing the control of the issuer of such securities, and such securities were and are not acquired in connection with or as a participant in any transaction having such purpose or effect.
Where Impax participates in collaborative engagement activities with other shareholders it does so on an independent basis and in accordance with its own policies. The purpose of such collaborative engagements is to facilitate an independent and free exchange of ideas and views among shareholders that relate to seeking improvement of the long-term performance of investee companies and/or changes in investee company practices, without the purpose of acquiring, holding or disposing of securities to effect or influence a change of control in investee companies or as a participant in any transaction having such purpose or effect.
While Impax may consult with other market participants on certain engagement efforts, Impax unilaterally determines whether and to what extent to engage with other stakeholders and all of Impax’s investment decisions are independent and based on its own, unilateral strategy for maximising return on investment.
