In 2025, climate education moved beyond awareness and into action.
Through the League for Green Leaders, students from five different countries didn’t just learn about sustainability – they measured their impact, changed real behaviors, and collaborated across borders to reduce our collective carbon footprint. What started as classroom learning became meaningful climate action with tangible results.
One of the most powerful outcomes of this year was seeing students understand that their everyday choices matter.
By tracking their decisions on transportation, food choice, and recycling, students collectively achieved over 22 tons of reduced carbon footprint. More importantly, they learned and experienced how to make more sustainable choices in their own lives – a greener mindset that will last far beyond a single school year.
Climate action became personal, practical, and empowering. “I’m trying to cut meat from my diet because it is very bad for the environment. “, “I decided to limit the amount of energy used in my home.” students told us how they expanded their learning to life.
The League for Green Leaders program brought together students from five countries in 2025, creating a truly global learning experience. Through collaboration and shared challenges, students explored sustainability not as an abstract concept, but as their shared responsibility.
They worked together to:
This global collaboration helped students see climate change as a connected, worldwide issue – and themselves as part of the solution.
In 2025, we also took a major step toward making climate education more accessible worldwide.
We began adding five new languages to our game iBiome-Changing Ice, allowing more students to engage with climate science in their own language. By combining game-based learning with real-world environmental challenges, iBiome game series helps students understand complex topics like ecosystems, climate systems, and human impact in a hands-on and engaging way.
This expansion means more learners, more inclusivity, and more impact in classrooms around the world.
None of this would be possible without our League Ambassadors – educators who are leaders in teaching sustainability and champions of meaningful STEM education.
These ambassadors:
Their leadership ensures that climate education is not an add-on, but a core part of how students learn, collaborate, and lead impactful action.
