Impax is committed to helping companies navigate the transition to a more sustainable economy. In so doing, we aim to mitigate risks and enhance opportunities for our clients.

We proactively engage with our portfolio companies and issuers to help us determine how they understand and perceive their own risks and opportunities. It is a valuable input to our investment decision-making process, which relies on a comprehensive understanding of the character and quality of our investee companies.

Effective engagement also provides an avenue for us to add value by encouraging companies to better manage their risks and to highlight issues that we believe pose the greatest challenges to the transition to a more sustainable economy.

Read about our recent global engagement activities and the impact of our work in the Engagement and Policy Advocacy Report 2022.

Our global engagement strategy is currently focused on four core issues:

  • Climate change
  • Environmental issues such as pollution and resource depletion
  • Human capital issues such as diversity, equity, inclusion, environmental justice, and health and safety
  • Corporate governance

We engage directly with our portfolio companies, including meeting with management teams and filing shareholder resolutions, and undertake collaborative engagements with other investors on critical issues. Proxy voting is also an important catalyst for dialogue.
