Microplastics: Macro risks and the cost of inaction

November 10, 2025 Share

Why should investors care about microplastics?

Effective packaging management is emerging as a key indicator of companies’ resilience and strategic foresight. Our Institute’s report, produced in collaboration with Planet Tracker, explores the financial and sustainability implications of microplastics exposure.

Here are some of the findings:

  • Concerns about the tiny particles created as plastics degrade have moved well beyond environmental debates. Regulators, investors and consumers increasingly see them as legal liabilities, financial exposures and reputational tests.
  • Companies without clear, organization-wide packaging policies risk being unprepared for tightening regulations and may appear less credible on sustainability to investors and customers.
  • Companies that lead with clear recycling goals and circular packaging strategies can reduce legal risks, build customer trust, and stay ahead of evolving climate and sustainability standards.
