World Cleanup Day 2026 is targeting the participation of five per cent of the world’s population as organisers seek to trigger long-term societal change in the fight against the global waste crisis.
The ninth edition of the global civic and environmental initiative is scheduled for September 20, 2026, under the campaign message “Strive for Five.”
In a statement, organisers revealed that research suggests that when a critical mass of about five per cent of a population takes collective action, it can help trigger lasting changes in society.
According to Heidi Solba, President and Head of the Global Network of Let’s Do It World, the campaign is seeking to move beyond the traditional concept of a one-day cleanup exercise.
“When a sufficiently large part of society acts together, it becomes a force that reaches far beyond a single cleanup day. Through our ‘Strive for Five’ message, we want to invite people, businesses, schools and governments around the world to experience how individual actions can together create a societal tipping point,” said Solba.
She said the movement also wants participants to look beyond collecting waste and focus on preventing waste from being generated in the first place.
“We no longer want to focus only on cleaning up waste that has already been created. Instead, we need to mobilise people to increase awareness and cooperation and ask how we can generate less waste, change consumption habits, and strengthen communities so that the actions of one day can create a long-term and lasting impact,” Solba added.
This year’s global coordination will operate from three cities; Riga, Tallinn, and Kyiv, with each serving a distinct role in connecting the worldwide campaign.
Riga will host the international broadcast and World Cleanup Day Village, while Tallinn will operate the global call centre to maintain contact with country teams.
Kyiv, meanwhile, will serve as the global media centre, coordinating international media coverage and stories from participating countries.
The main World Cleanup Day celebration will take place in Shaoxing, China, from September 19 to 21, in cooperation with UN-Habitat and the host country.
In Ghana, activities will take place a day earlier, with a cleanup exercise scheduled for Ananse Beach in Nungua on Saturday, September 19, 2026, at 7:00 a.m.
World Cleanup Day has grown considerably since its origins in Estonia in 2008, when 50,000 people participated in a nationwide cleanup that lasted just five hours.
The initiative developed into a global movement, with the first World Cleanup Day held in 2018.
Let’s Do It World, which has coordinated the movement since 2019, said 25 million people across 190 countries and territories participated in World Cleanup Day in 2025.
Since 2018, the movement has recorded a cumulative 139 million participants across 211 countries and territories, who have collectively removed more than 870,000 tonnes of waste.
Media coverage of last year’s campaign also potentially reached 2.4 billion people globally, according to data from media monitoring company Meltwater.
The movement is also positioning World Cleanup Day as a platform for strengthening communities facing crises, with teams in countries including Ukraine, Colombia and Nepal carrying out activities amid wars, wildfires, earthquakes and floods.
Organisers say the experience raises broader questions about how collective action can help communities build trust, share knowledge, and become more sustainable and resilient.
Participation in World Cleanup Day is open to individuals, families, schools, workplaces, community groups and other organisations. Participants can join activities organised by local coordinators or organise their own cleanup in a safe and permitted location.
Organisers have advised participants to observe local regulations, use appropriate protective equipment and avoid hazardous, medical, military or unidentified materials. They have also encouraged the proper sorting and transfer of collected waste to authorised disposal or recycling services.
The United Nations recognised the growing global significance of the initiative in 2024 by adding September 20, World Cleanup Day, to its calendar of international days.
With the “Strive for Five” campaign, Let’s Do It World is seeking to turn that global recognition into broader participation and, ultimately, sustained changes in how individuals, businesses, schools, and governments approach waste and environmental responsibility.
