Change The

Schools are a microcosm of the city. They share the same environmental problems as cities - waste, air quality, energy-inefficient buildings and carbon emissions.

Why Sustainable Schools?

Schools are a Microcosm of the City

Just like the city, schools are constrained by space, money, and time. And in a school, just like the city, there are diverse interests that aren't always aligned.

But, at the scale of the school, the seemingly daunting sustainability challenges of the city become addressable - they show up at a scale that students can get their arms around, in a system that's easier for them to influence, and on a timeframe in which outcomes are more quickly apparent.

So rather than just being a place where students learn about sustainability problems, schools are an ideal context in which to model sustainability solutions and cultivate eco-literacy.

The campus can be a living laboratory. And if we get it right on the campus, schools can show the city how it's done. Schools can show us the sustainable future we want.

A School Leader's Perspective

A Whole-School Approach to Sustainable Development

"When Greta Thunberg stood outside the Swedish Parliament in September 2018 with a sign saying ‘School Strike for Climate’, she captured the imaginations of young people everywhere, including those at Chinese International School (CIS) in Hong Kong.

I recall that moment vividly, for I had only just joined CIS and was keen to discover what the students at my new school thought of her initiative. Their response was simple: sustainable development should be our number one concern."

What is a Sustainable School?


Many schools aspire to the ideal of a sustainable campus but live with the reality of older buildings that weren't designed to the highest environmental standards. But there are multiple ways to improve the environmental performance of a campus, from energy efficient appliances to redesign retrofits, low-impact cleaning materials and green landscaping - and they're all a source of learning opportunities to supplement what's taught in the classroom.


To develop eco-literate students with the capacity to create and lead a sustainable society, we must do more than teach about sustainability, we must equip them with the skills and competencies to tackle real-world environmental challenges. A comprehensive experiential eco-literacy curriculum is embedded in the campus and everything the school does, from the way the buildings are designed, to the type of food served in the canteen and how decisions are made. There's material here for every subject and every grade level.


Sustainability is a community practice - it depends on a network of relationships inside and outside the school, relationships which require effective collaboration and cooperative decision-making to maintain.

These skills are among those the students will need to tackle our many environmental challenges. The road to becoming a sustainable school, therefore, offers many opportunities for staff and students to model and learn these skills.


Sustainable schools have a culture of sustainability. They do more than teach sustainability and model it in certain ways, their commitment to it is reflected in their mission and values, they integrate it into their governance and operations, including: long-term strategy, policy, decision-making, target-setting, partnerships with suppliers and daily practices, and they continuously engage a wide range of students, parents, staff and members of the external community in sustainabliity initiatives.


Sustainable schools understand the fundamental role of communication in supporting the other 4Cs and embedding sustainability in the ethos culture and everyday practises of the school community. Sustainable schools develop communication strategies, dialogues and narratives that facilitate and enrich their sustainability journey.

Scaling our Impact

In one sense, the world’s not such a big place – from one person (100) to the whole planet (109) is only 9 steps. But let’s face it, trying to influence everyone just isn’t practical.

On the other hand, influencing just a few people doesn’t have much impact. Perhaps there’s a trade-off between a scale that’s easy and one that makes a difference. Maybe there’s a sweet spot somewhere in the middle?

Turns out it’s 105 … or roughly the population of 100 schools and the school system is a great vehicle for scaling change. Which is why, at Metanoia, we’re focusing on schools. 100 of them to start with for optimum reach and optimum impact.

And we’ll scale from there. When you do the math, it would only take 10,000 Metanoia’s to change the world.
