Now more than ever, the world needs changemakers making our planet sustainable


At Green School, our mission is to nurture changemakers with a passion and a relentless commitment to make our world sustainable. We believe each one of our students has a unique potential to affect change and make a difference.

Whether that’s through starting their own permaculture farms, setting off a global movement to ban plastic, advocating for climate change right out of college or following their passion to pursue a university degree.


Meet some of our changemakers and hear how their ideas are shaping the world.

Nicholas was in the first-ever grade 8 class at Green School Bali. He could only spend one year here, but it had a profound impact on his journey.
