Climate change often feels overwhelming and disconnected from our daily lives, which makes progress slow. At YCIS Hong Kong, the students explored how empowering young people to align their passions with climate action can lead to tangible solutions. Through interdisciplinary collaboration—scientists painting CO₂-absorbing murals, gardeners and tech enthusiasts building sustainable herb gardens, and creating pathways from recycled materials—they transformed climate action into something visible and achievable. This talk will highlight how student-led, passion-driven initiatives can drive meaningful change, demonstrating that classrooms can be the starting point for collective climate solutions. The speaker hopes to inspire a new wave of environmental action. Fiona is a higher school student passionate about combining environmental stewardship with innovative solutions.
