HISTORY
World Cleanup Day
WCD is the biggest civic action movement in human history. It has been officially recognised by the UN and it takes place each year on 20th September.
Since 2018, over 139 million people from 211 countries and territories have joined forces on WCD to help create a cleaner planet, collecting more than 873,289 tonnes of waste.In 2025, a record-breaking 25 million people participated across 190 countries and territories. As a result, habitats have been restored and animals, plants, rivers, lakes, parks, and streets have been protected from pollution.
Digital Cleanup Day
The first Digital Cleanup Day was organised in Estonia by a telecommunications company in 2019. Telia Estonia had identified digital waste as a growing environmental concern, and decided to invite individuals, organisations, schools, and businesses to clean their digital environments and get rid of unused data, redundant files and forgotten emails. Over 70 companies and several thousand people took part and about 1 million GB of data was deleted.
Participation kept growing nationally until by 2023, around 400 organisations and more than 10,000 people were taking part. Telia Estonia recognised digital pollution as a global challenge, and approached Let’s Do It World, the Estonian-based organisation behind the global World Cleanup Day movement, with a proposal to expand Digital Cleanup Day internationally.
