United StatesImpax is a specialist investor in the transition to a more sustainable economy. We believe superior capital returns across asset classes can be generated by investors who better understand the opportunities and risks associated with the transition to a more sustainable global economy.
Impax’s sustainable investment approach is built on three main steps:
1. Risk and opportunity assessment related to industries or activities
Using proprietary tools including the Impax Sustainability Lens, thematic taxonomies, and Fixed Income sectoral tiering, we identify risks and opportunities associated with the transition to a more sustainable economy across industries and asset classes.
2. Resilience analysis related to companies and issuers
At the company and issuer-level, we evaluate investments’ resilience in navigating various environments in the transition to a more sustainable economy. This enables a deeper and broader understanding of corporate structures, oversight mechanisms, risk management capabilities and processes and transparency.
- Corporate Resilience Analysis – Proprietary analysis for equities (formerly known as “ESG”) which considers governance structures, the management of material environmental and social risks, climate risks (physical and transition), human capital management, and controversies.
- Issuer Resilience Analysis – Proprietary analysis for fixed income investments (formerly known as “ESG”) which considers governance structures, climate risks, human capital indicators, and controversies.
3. Stewardship
Insights from our resilience analysis guide our engagement and proxy voting efforts. These stewardship activities enable more effective monitoring of our companies and issuers and aim to strengthen their structures, processes and disclosures over time.

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.
