If the society does not change habits, in five years this type of data will reach the 91 Zettabytes, quadrupling its current volume.

The evolution of the technology, with the introduction of tools such as the cloud, is revolutionising the way we work, communicate, enjoy entertainment… to live.

But the fact that users do not see what is hidden behind certain applications does not mean that their impact on the environment is invisible. The intensive data generation, whose level of storage world is in the tens of Zettabytes, also pollutes. This is especially critical in the case of the Dark Data, the data dark, useless, that are saved in the systems, which are not used and of unknown content. The infrastructure on which they reside, consume energy and end up driving out unnecessary levels of carbon dioxide to the atmosphere.

A study of Veritas Technologies determines that this year the storage of Dark Data generated 5.8 million tons of CO2. “all over the world,”, says José Manuel Petisco, director general of Veritas Spain, “the dark ones are producing more carbon dioxide than 80 different countries contribute individually”

Around 52 % of all the data that are accumulating in these times companies are data dark. And, unless the society begins to change habits, to in five years, this type of data will arrive at 91 Zettabytes, quadrupling the current volume.

“to Filter these data and to delete information which is not needed, it should become a moral imperative for companies around the world,”, pointing Petisco.

To take care of the environment, companies have to revise their strategies of management data and implement changes. “they Need to understand this type of hidden data, and the storage policies around, for we do not see grow up without as the spiral of harmful emissions to the environment,”, says the general director of Veritas.

Here “we can all play a role individually decisive, as almost all of us store data that we will never access, just because cloud storage is so cheap and is available for us – thousands of videos and photos that will never look, or emails that we can never read again- there are hundreds of millions of people by gathering without a real purpose”, explains Petisco, who insists that “businesses and consumers around the world need to learn how to manage their data for the good of the planet”.
