Companies, Citizens, Schools, Communities… Join the movement !

An event for everyone

The Cyber World CleanUp Day (Cyber WCUD) allows anyone to organise or participate in a data clean-up operation. Individuals, organisations, schools, communities, anyone can organise a data cleansing operation and form a team capable of taking up the challenge !

Why participate ?

Cleaning up your data is an act that allows you to relieve your digital equipment (computers, tablets, smartphones), the servers of your organisation (company, local authorities, etc.) and/or to relieve the Cloud.

In this way, you are helping to extend the life of your digital equipment and limit online over-storage.

How to participate ?

You can become Ambassadors, Organisers or Participants. Each person can play a different role, depending on his or her wishes.

Your event can be private or public, i.e. open to all or only reserved for the employees of an organising company for example.

Where does the environmental footprint of digital technology come from?

The environmental footprint comes first and foremost from the mass production of digital equipment that we constantly renew. Moreover, in terms of usage, the footprint comes largely from users’ equipment and less from the huge data centres often wrongly accused of being the main factor of digital pollution.

Why is it so important to clean up your data ?

We firmly believe in the need to make the immaterial material in order to better perceive its damaging power. Accumulating data on your smartphone or computer accelerates the obsolescence of your hardware, contributing to its slowing down.


Storing massively in the cloud implies three essential things:

1/ One opening = one download

The need to download a document each time you want to consult it. E.g. : if your smartphone is not overloaded with too many photos, you can store them directly on it rather than in the Cloud, which avoids downloading them each time you open them.

2/ More complex research

The complex search for items in an anthill of documents. Who hasn’t stored a v0 file, then v0.1, then v0.1-beta, then actually v0-final in another folder? etc.? This multiplies the number of server requests to find the right file.

3/ More and more servers

Finally, even if the trend is to reduce the energy consumption of servers, the first energy saving is the one that is not consumed ! Thus, reducing the amount of data stored in the cloud means not increasing the number of servers already deployed.
