Established in 2018, Green Hour aims to promote a sustainable lifestyle through education, events and campaigning. Having already organised multiple beach cleanups, 'plogs' as well as Hong Kong's first 'Plastic Attack', Green Hour has begun establishing itself in the area. More recently, Green hour has started its Bun Run initiative, rescuing surplus food items from being sent to landfill and distributing them, as well as other essentials, to those in need in the community. To date, Green Hour supports roughly 100 individuals on a weekly basis, with plans to expand over the coming months.
