How VGS Students Are Leading the Sustainability Revolution in Ho Chi Minh City
From rooftop gardens to AI-powered waste sorting systems, VGS students are transforming their campus into a living laboratory for sustainable innovation — and inspiring their communities to follow suit.
A Campus-Wide Sustainability Ecosystem
Walking through the Van Lang Global School campus in Ho Chi Minh City's District 7, visitors immediately notice something different. Solar panels line the walkways, providing shade and clean energy simultaneously. Rainwater harvesting tanks, designed and built by engineering students, collect water for the school's extensive garden network. In the cafeteria, a student-designed digital display shows real-time energy consumption data, waste diversion rates, and the carbon offset achieved by the school's sustainability initiatives.
These visible changes are just the surface of a deeper transformation. Over the past three years, VGS has systematically integrated sustainability into every aspect of school operations and curriculum, driven largely by student initiative and innovation. The result is a campus that functions as a living laboratory — every system, from waste management to energy production, serves as both a practical solution and a teaching tool.
The Green Innovation Lab
At the heart of VGS's sustainability program is the Green Innovation Lab (GIL), a purpose-built makerspace where students develop, prototype, and test sustainability solutions. Founded in 2024 with seed funding from the VGS Parent Association and corporate sponsors, the GIL has produced some remarkably sophisticated projects.
The most celebrated is SmartSort, an AI-powered waste classification system developed by a team of five Grade 11 students. Using computer vision and machine learning, SmartSort can identify and sort waste into twelve categories with 94% accuracy — significantly outperforming the industry standard. The system has reduced contamination in VGS's recycling stream by 67% since its implementation.
From Campus to Community
"When we started, we just wanted to solve our own school's waste problem," explains Le Thanh Tung, one of the SmartSort developers. "But then local businesses started asking if they could use our system too. That is when we realized this could be bigger than just a school project." SmartSort has since been piloted at two local shopping centers and a hospital, with plans to expand to all District 7 public buildings by mid-2027.
The rooftop hydroponic garden project tells a similar story of campus innovation scaling to community impact. What began as a biology class experiment has grown into a fully operational urban farm producing over 200 kilograms of vegetables per month. The produce supplies the school cafeteria, with surplus donated to local food banks. More importantly, the project has spawned a community outreach program where VGS students teach urban farming techniques to residents in nearby apartment complexes.
Curriculum Integration
Sustainability at VGS is not an extracurricular afterthought — it is woven into the academic fabric of the school. In mathematics classes, students analyze real energy consumption data from the school's solar array. In literature, they explore environmental narratives from Vietnamese and global authors. In economics, they model the financial viability of sustainable business practices using data from the school's own green initiatives.
"The key insight was that sustainability is not a subject — it is a lens through which every subject becomes more relevant and engaging," says curriculum coordinator Dr. Pham Thi Mai. "When students see the direct connection between what they learn in class and real-world challenges they care about, motivation and retention increase dramatically."
Recognition and Future Plans
VGS's sustainability program has attracted international attention. The school received the UNESCO ASPnet School Award for Environmental Innovation in 2026, and was featured in a Harvard Graduate School of Education case study on sustainability education in developing countries. Principal Dr. Tran Van Minh sees this as just the beginning: "Our students are proving that young people in Vietnam are not just learning about sustainability — they are leading it. The innovations coming out of this campus will shape how our city and our country approach environmental challenges for decades to come."
