Sustainability has become an urgent priority for schools worldwide. At Cogdel Cranleigh School Changsha (CCSC), we have taken meaningful steps to embed environmental stewardship into our school culture. Our award-winning initiative, the CCSC Sustainability Pledge, is a student-led programme designed to instil responsible environmental habits and promote sustainability at all levels of the school community.
Identifying the Challenge
As an international school, we recognised that while students were aware of global environmental issues, there was a gap between knowledge and action. We sought to bridge this gap by embedding sustainability into daily school life, encouraging students to take ownership of their impact on the environment. We introduced the CCSC Sustainability Pledge to ensure that every student and staff member contributed to sustainable practices in a tangible way.
Implementation and Key Initiatives
The Pledge operates across different age groups with age-appropriate sustainability commitments. Primary students focus on simple actions like turning off lights and carrying reusable water bottles, middle school students go meat-free one day a week and avoid single-use plastics, while high school students track their carbon footprints and write articles on environmental issues for the school newspaper.
In addition to these sustainability-focused habits and activities, we have made physical improvements to our campus. The school cafeteria has eliminated disposable containers and plastic straws, and every classroom now features reusable water bottle stations. Recycling bins have tripled in number, and energy-efficient lighting has been installed throughout the campus. Perhaps the most impactful project has been the transformation of a previously unused space into a school allotment, where students grow vegetables that are either used in the cafeteria or donated to the local community.

To further support this initiative, students took the lead in creating an internal sustainability audit. A group of middle and high school students assessed energy usage, waste production, and recycling habits, providing recommendations for further improvement. This student-driven approach fosters a sense of responsibility and allows students to witness firsthand the results of their efforts.
Impact and Evidence of Success
Since launching the CCSC Sustainability Pledge, we have seen measurable improvements in waste reduction and environmental awareness. Daily food waste has dropped by 35kg, and plastic waste has significantly decreased. The school allotment has provided a practical and educational opportunity for students to learn about sustainable agriculture while also benefiting the wider community.
Beyond the campus, our initiative has inspired local community groups to adopt similar sustainability strategies. We actively share our practices with neighbouring schools, amplifying the impact of our efforts. One notable example is our collaboration with a nearby public school, where CCSC students conducted sustainability workshops, introducing younger students to simple environmental actions that can be implemented at home and in their classrooms.
Students have also taken their knowledge beyond the school gates, advocating for environmental responsibility in their own communities. Several students have initiated personal sustainability projects, such as organising neighbourhood recycling drives and launching social media campaigns to raise awareness about single-use plastics. These independent efforts illustrate how the programme has inspired students to become proactive environmental stewards.
Sustainability and Longevity
To ensure the long-term success of the initiative, we have embedded sustainability themes into our curriculum. Students calculate water savings in mathematics lessons and explore the feasibility of renewable energy in science and engineering courses. Additionally, sustainability committees, composed of students, staff, and faculty, set and review new sustainability goals regularly.
By making sustainability student-led, we cultivate a culture where each new cohort takes responsibility for continuing the initiative. Partnerships with local environmental organisations and other schools further strengthen the programme’s longevity.
Looking ahead, CCSC aims to establish an annual sustainability conference, bringing together students from international schools across China to exchange ideas and best practices. This initiative will not only reinforce our own sustainability efforts but also encourage cross-school collaboration in tackling global environmental challenges.
Additionally, we are exploring ways to integrate emerging technologies into our sustainability initiatives. With the rise of AI and data analytics, we plan to introduce digital tools that allow students to track their energy and water consumption more accurately. By using real-time data, students can gain deeper insights into their environmental impact and make more informed decisions about conservation strategies.
Embedding Diversity, Equity, Inclusion, and Justice (DEIJ)
A key principle of the CCSC Sustainability Pledge is ensuring that all students, regardless of background, can contribute to and benefit from sustainability efforts. By tailoring age-appropriate actions, we ensure participation from every student, reinforcing a sense of shared responsibility. The school allotment not only teaches sustainable land use but also addresses social justice by supporting food access in the local community.
Our curriculum incorporates discussions on environmental justice, educating students about how climate change disproportionately affects marginalised communities. This holistic approach ensures that sustainability is not just an environmental issue but also a matter of equity and inclusion.
Beyond the direct educational benefits, we have also fostered a culture where sustainability is linked to wellbeing. Research suggests that engaging with nature has positive effects on mental health, and we have witnessed this firsthand. Our school allotment has become not just an environmental project but a space for relaxation and mindfulness, where students take breaks from their academic workload while contributing to a meaningful cause.

Practical Takeaways for School Leaders
For international schools looking to implement a similar initiative, here are some key recommendations:
- Start with Student Leadership: Empower students to take charge of sustainability initiatives. Their engagement ensures longevity and enthusiasm.
- Make Actions Age-Appropriate: Assign sustainability commitments based on age groups to ensure accessibility and impact.
- Integrate Sustainability into the Curriculum: Connect environmental topics to subjects like mathematics, science, and social studies.
- Foster Community Partnerships: Work with local organisations to amplify impact and provide real-world learning experiences.
- Monitor and Evaluate Progress: Track key metrics like waste reduction, recycling rates, and energy savings to measure success and adapt strategies accordingly.
“A key principle of the CCSC Sustainability Pledge is ensuring that all students, regardless of background, can contribute to and benefit from sustainability efforts.”
The CCSC Sustainability Pledge has transformed sustainability from an abstract concept into an actionable, schoolwide movement. By integrating environmental responsibility into daily school life, we have fostered a culture where students are not just passive learners but active changemakers. Our experience demonstrates that with student leadership, practical commitments, and a structured approach, international schools of all sizes and orientations can successfully embed sustainability into their communities. By sharing our journey, we hope to inspire other schools to embark on their own sustainability journeys and collectively work towards a more environmentally responsible future.
