What is the Transformative Change Assessment (TCA)?

The IPBES Transformative Change Assessment is a landmark global science-policy assessment that:
  • Explores how we can address the root causes of biodiversity loss and pathways for transformative change
  • Was developed over 3 years by 101 experts from 42 countries
  • Synthesizes over 7,000 references and 800+ visions of sustainable futures
  • Includes over 400 case studies of strategies and actions for systems-wide change

The IPBES Transformative Change Assessment offers a powerful lens for understanding—and advancing—systemic change. But how can these insights be applied in practice? On May 8, 2025, the Transformations Community joined cCHANGE, and SocSES to host a global webinar exploring just that: how boundary organizations can activate the TCA to catalyze collective action for sustainability.

Watch the full session and learn how the TCA can support transformative action.
