This blog has been authored by Brenda Giacometti Komel, Director of Global Community Development at Take Action Global, where she leads community growth, partnership development, and global engagement initiatives that connect educators and learners around the world. With a background in international development, human rights, sustainability, and education, she has worked across the globe supporting collaborative initiatives that empower teachers and young people as changemakers.

Teachers are at the heart of education transformation. As the world grapples with the interconnected challenges of climate change, biodiversity loss, inequality, and sustainable development, educators are increasingly being called upon to help learners navigate complexity, develop critical thinking skills, and become active participants in shaping a more sustainable future.

Yet teachers cannot be expected to carry this responsibility alone. To effectively prepare learners for the challenges of the 21st century, educators need access to high-quality resources, professional learning opportunities, global networks, and meaningful support systems that recognize their expertise and amplify their impact.

At Take Action Global (TAG), we believe that teachers are among the most powerful catalysts for change. Through global collaboration, project-based learning, and real-world action, we work alongside educators to help transform classrooms into spaces where students learn not only about global challenges but also how to become part of the solution.
 

Supporting teachers through global collaboration

One of the most significant challenges teachers face is finding practical ways to connect global issues to locally-relevant learning experiences. While sustainability and climate education are increasingly recognized as priorities, many educators report needing greater support, resources, and opportunities for collaboration.

Take Action Global addresses this need by connecting teachers to a global network of peers who share ideas, best practices, and innovative approaches to teaching sustainability and global citizenship. By fostering cross-cultural collaboration and providing free educational resources, educators can access tools that help bring real-world learning into their classrooms while remaining aligned with local curricula.

This approach not only strengthens teacher capacity but also helps reduce professional isolation by creating opportunities for educators to learn from one another across borders and contexts.
 

Climate Action Project and LEGO Build the Change: Two classroom initiatives empowering teachers to inspire student action and drive local impact

A flagship example of this work is the Climate Action Project (CAP), one of the world's largest climate education initiatives.

Each year, teachers and students from around the globe come together to explore climate-related topics through collaborative learning experiences, project-based activities, and meaningful dialogue with peers from different countries. The initiative provides educators with ready-to-use resources, lesson plans, professional learning opportunities, and access to a vibrant international community committed to climate education.

More importantly, CAP is designed to support teachers as facilitators of learning rather than requiring them to become climate experts. Through structured activities and global connections, educators gain the confidence and resources needed to engage students in complex environmental issues while fostering critical thinking, creativity, communication, and problem-solving skills.

Another initiative helping teachers bring sustainability education to life is Build the Change, offered in collaboration with the LEGO Group.

Through a series of student challenges, Build the Change encourages learners to imagine, design, and share solutions to real-world issues related to sustainability and community resilience through a playful learning approach. The challenges provide educators with fun, accessible entry points for discussing complex global topics while promoting creativity, collaboration, and student agency. These are flexible resources that can be adapted across age groups, learning environments, and curriculum areas.

By creating opportunities for student voice and participation, the initiative reinforces an important principle: young people are not only future leaders but active changemakers today.
 

Why supporting teachers matters

As UNESCO and the Teacher Task Force have pointed out multiple times in the past, global efforts to achieve SDG 4 and preparing learners for an increasingly complex world depends on a well-supported teaching profession. Teachers need access to relevant professional learning, practical resources, collaborative networks, and opportunities to contribute their expertise to educational transformation.

At TAG, we have seen firsthand how educators rise to the challenge when they are provided with meaningful support, trusted as professionals, and connected to a global community of

practice. The more than 26 million teachers and students reached through our programs across over 190 countries are a testament to the multiplier effect that occurs when educators are empowered to lead.

Every day, teachers participating in initiatives such as the Climate Action Project and Build the Change are helping learners develop the knowledge, skills, values, and agency needed to create a more sustainable and just future.
