Millions of volunteers in 150 countries uniting to clean up the world in a single day. Be part of the biggest civic action in human history, and help launch a cleaner future. On 15 September, volunteers and partners worldwide will come together to rid our planet of trash – cleaning up litter and mismanaged waste from our beaches, rivers, forests, and streets. A powerful ‘green wave’ of cleanups will start in New Zealand and end 36 hours later in Hawaii, with millions of people working towards one goal: a clean and healthy planet. World Cleanup Day harnesses the power of everyday people to achieve incredible things by joining together. Its beauty lies in cooperation and collaboration: building bridges between disparate communities, and including all levels of society – from citizens, to business, to government.
