Yes, this wonderful virtual world that we work in every day. This digital universe filled with cloud, Wi-Fi and thousands of internet searches that make us forget the environmental impact of our excessive consumption of new technologies. Behind each message, call, email or video downloaded, viewed or sent, hides real energy consumption.
What is the carbon footprint?
This is the amount of CO² emitted by an activity/person/group/organisation through its consumption of energy and raw materials. It contributes to global warming and translates into the amount of forest area needed to emit that much carbon dioxide.
The arrival of the Internet has had a significant impact on our daily life and our habits. Today, to transmit a message we use email, SMS, instant messaging and social networks and therefore less paper and transport.

And to store all this information you need data that have a huge environmental impact.
In short, clicking is polluting.
How does an email pollute?
Behind the sending and storing of an email hides an internet network and computer servers that work 24/7, 365 days a year.
