Fighting back plastic pollution in every corner of the city

Green Hour has been working tirelessly since 2018 to ensure that our streets, hiking trails and beaches remain clean.

Plastic pollution is a serious issue globally. Hong Kong is no different.

Through our #Trashtag Challenge we aim to bring the community together to green our city whilst having fun, meeting new people and doing something good both for ourselves and for the wider community.

Corporate Beach Cleanup

Hong Kong has hundreds of beaches. Many of them are susceptible to trash both from visitors and washed in from the sea.

See how you can help!
