IISD Annual Report 2024–2025

Transforming Bold Ideas Into Real-World Change

In this annual report for 2024–25, you will see that the International Institute for Sustainable Development's (IISD's) reputation as a convenor, a trusted thought leader, and a go-to source on key issues within the sustainable development field is stronger than ever.

November 27, 2025

Right now, IISD is working with more than 100 countries on projects that connect government leaders, policy-makers, and those who influence them to ensure impacts are made strategically and at scale.

As a sustainable development think tank with more than 35 years of experience in the field, it's safe to say top-quality research will always be essential to IISD's mission. But to be effective, research cannot be conducted in a vacuum or published in isolation—it must be informed by real-world issues, shaped by a diverse range of data, voices, and knowledge holders. And ultimately, it must serve a purpose. The best research will create a foundation for action, kickstarting dialogue, policy change, investments in new projects, and commitments to make positive change.

It's this bigger picture that IISD is focused on. Increasingly, we're leaning into work that drives tangible, meaningful impact—both globally and locally. And for us to succeed, it's critical that we don’t do this alone.
