About the Global Movement
From one country to 139 million people.
World Cleanup Day is the biggest civic environmental movement in human history, uniting 212 countries and territories on the UN Calendar.
The Spark · 2008
How 50,000 Estonians started a global wave.
In 2008, in the small Baltic nation of Estonia, over 50,000 people—equal to 4% of the country's population—stood up on a single day to clean up the entire country. In just five hours, they removed over 10,000 tons of illegally dumped waste.
The simplicity and spirit of the “Let's Do It!” attitude spread across borders. Other nations adopted the one-country, one-day model, evolving into a 36-hour green wave following time zones from Fiji across Asia, Europe, Africa, and the Americas to Samoa.
Today, World Cleanup Day is an official United Nations International Day (UN General Assembly Resolution 78/122), mobilizing up to 25 million active participants each year.

Our Philosophy
Three Core Values
Cooperation
Go far together
We bring together citizens, businesses, NGOs, and governments. Waste belongs to no one and affects everyone.
Positivity
Solutions over blame
We do not point fingers or prophesy doom. We inspire constructive, uplifting community action against trash blindness.
People
Every volunteer is a leader
Systemic change starts within people. Anyone can pick up trash, lead a neighborhood crew, and transform culture.
