Global Schools Program Launches Case Study Guidebook on International Day of Multilateralism and Diplomacy for Peace

New York, New York (April 24, 2026) — The UN Sustainable Development Solutions Network's (SDSN) Global Schools Program is pleased to launch the case-study guide "Practicing Education for Sustainable Development: Case Study Guide for Educators, Volume 3.” The release coincides with the International Day of Multilateralism and Diplomacy for Peace, a United Nations observance that highlights the importance of consultation, inclusion, and solidarity.

“This guide brings together the work of educators and students across the Global Schools community who are actively shaping what education for sustainable development can look like in practice,” said Amanda Abrom, co-author and Global Schools Director. “It reflects a shared commitment to embedding sustainability, creativity, and real-world relevance into teaching and learning. As this work continues to grow, we remain focused on supporting our global network with accessible resources, practical insights, and ideas that can be adapted and applied across diverse contexts.”

The guidebook includes the experiences of approximately 30 Global Schools Advocate Alumni, detailing their work on Education for Sustainable Development (ESD) projects across varying levels of curricular integration. It includes a synopsis of ESD lessons, activities, and implementation strategies for primary and secondary education stakeholders, as well as insights into school-wide approaches and key lessons learned.

This year, educators were asked to self-identify the primary level of ESD integration at their school by selecting one of the four categories:

• Classroom Level: ESD concepts integrated into individual subjects or lessons;
• Collaborative Projects & Interdisciplinary Learning: Joint initiatives across subjects and grade levels;
• Schoolwide Approach: Coordinated ESD practices embedded into institutional culture;
• Community Partnerships and Outreach: School-community collaborations advancing action beyond the classroom.

These classifications aim to make the case studies more relevant and adaptable for educators worldwide.

Global Schools extends its gratitude to the educators featured in this publication: Adamson-Abiodun Temitayo, Amadou Mariko, Amanda Winnett, Amar Sad, Batool Kazmi, Büşra Dursun, Crystal Pottebaum, Dorothea Müller, Edwin Quinosa, Emmanuel Omeiza Momoh, Federica Quartesan, Glenda Torres, Gloria Romlin, Jessica Flórez Murcia, Jo Au Lok Yee, Mani Ram Ghimire, Marcela Villán, Maria Jonaper Palmares, Mariella Fasanelli, Mary Akatch, Megan Vosk, Murali Krishnan, Nwa Abbas, Rafi Cristobal, Samreen Haider, Sania Rasool, Shweta Awasthi, and Yaya Dama.

Global Schools hopes that this guidebook will inspire educators to incorporate ESD into their curricula and communities, contributing to the advancement of the Sustainable Development Goals and a more sustainable future.

Selected testimonials from featured educators include:

“Through Casnati for ESD, we have developed a regenerative learning ecosystem that integrates Education for Sustainable Development as a systemic approach across curriculum, governance, and partnerships. The Global Schools Program has played a key role in connecting this locally grounded work to a broader international framework aligned with the SDGs.” – Federica Quartesan, Global Schools Advocate, Lead, Casnati for ESD at Centro Studi Casnati, Italy

“The most profound impact of this project was seeing every student, regardless of their background, develop the critical consciousness needed to address global injustices. By moving beyond simple reusing and recycling toward a deep, personal commitment to resource stewardship, we are not just teaching a curriculum; we are nurturing the mindset that a sustainable world is built through our collective, everyday choices.” – Jo Au Lok Yee, Global Schools Advocate, IBPYP Teacher at the Australian International Academy of Education (Strathfield) & Education Operations Director at Inspire Tomorrow Education

“Through the 'For... Better' initiative with the Global Schools Program, I implemented practical solutions aligned with the Sustainable Development Goals, using technology and social media, and addressing the interests of this generation, with the aim of instilling sustainable thinking, empowering our students with leadership and innovation skills. Today, their sustainable mindset enables them to creatively develop solutions for environmental and community challenges.” – Amar Sad, Global Schools Advocate, Mentor, Syria

“Through Challenge-Based Learning, the Sustainable Development Goals became more than global targets for my students. They became personal responsibilities rooted in their own communities. When learners begin to see themselves in the work of sustainable development, they don’t just understand the goals; they start acting on them.” – Edwin Quinosa, Global Schools Advocate, Social Studies Teacher, De La Salle Santiago Zobel School, Philippines

“Through the Sustainability Summit, our students did not just learn about the SDGs—they began to see themselves as active contributors to change. Global Schools helped us turn sustainability from a topic in the classroom into a living school culture.” – Büşra Dursun, Global Schools Advocate, Biology Teacher and Sustainability Educator, Türkiye

“My Green Voices Project: Language for Sustainability, which I used for this case study, was inspired by my teaching experience in a rural agrarian community, where students faced environmental challenges such as deforestation and bush burning. The project gave them a platform to creatively engage with sustainability and was recognized among the top 11 projects at the 2024 Teachers CoP Conference in Azerbaijan. Since joining the Global Schools program in 2021, this experience has shaped my journey, helping me secure a Commonwealth Scholarship for my Master’s in Publishing Studies at the University of Stirling, United Kingdom, which I completed last year, as well as fellowships, including the Young African Leaders Initiative and the Mastercard Foundation, which supported my travel to Ghana.” – Emmanuel Omeiza Momoh, Global Schools Advocate, Educational Officer 2, Government Secondary School, Yashikira, Kwara State, Nigeria
