The catalyst behind the initiative
The Case Study Database
Developed and championed by Regions4, the Case Study Database is a unique and growing collection of real-world examples showcasing how regional governments are driving impactful solutions to today’s most pressing environmental, social, and economic challenges.
By documenting these success stories, the database serves as a powerful resource for subnational governments worldwide, enabling them to learn from proven strategies and adapt them to their own regional contexts. Whether addressing climate change, biodiversity conservation, disaster resilience, or sustainable development, these case studies highlight actionable solutions that can be replicated and scaled.
Each case study provides in-depth insights into:
The institutional framework that enabled its success
Key project components
Direct and indirect impacts
Financial sustainability
Successes, challenges and lessons learned
To ensure global accessibility, all case studies are available in Spanish, French and English
Your region can also submit a case study on the website!
