Green IT and hybrid work: towards a more responsible digital worldLire l'article
28 March 2022
Digital technology has long been seen as an alternative for more responsible consumption, but its over-consumption can lead to certain ecological limits.
Indeed, according to the latest ArchiMag report, the world’s digital sector accounts for 4% of greenhouse gases.
Moreover, data storage alone could be capable of generating emissions of up to 14% by 2040 (Source: Big Data)
To reduce this carbon footprint, the notion of Green IT has emerged to promote initiatives in favor of sustainable development and to fight against this digital pollution.
Green IT is a set of information and communication technologies that aim to reduce the carbon footprint and contribute to achieving sustainable development goals.
The digital transition is underway, encouraging ever more digital uses, and accelerating the amount of data on a daily basis, so how can companies be made responsible for the ecological consequences of their transformation? What roles can they play in reducing digital pollution? How to promote green IT?
The COVID pandemic has accelerated digital uses: videoconferencing, e-commerce, teleworking, collaborative work, the cloud, and more.
Thanks to the cloud, companies have been able to continue their business “almost” as usual by accessing data from anywhere and from any device. It has also enabled the smooth exchange of data and the continuity of collaborative work between employees.
From an ecological point of view, the use of the cloud has also facilitated:
A study has shown that switching from traditional On-Premises software applications to their Cloud equivalent could reduce energy consumption by 87%.
The cloud, sometimes affiliated with green washing, can bring a certain limit to the energy consumption of companies.
Data centers are essential for storing billions of cloud data. However, they consume a lot of electricity because they run continuously and are a great source of heat.
Air conditioning and cooling systems account for 40-50% of data center energy consumption. (Source: planetoscope)
Especially since, with the exponential use of collaborative tools and hybrid work, energy consumption is likely to increase considerably in view of the massive amount of data sharing and bandwidth required to make the services accessible 24/7 (Teams videoconferencing, SharePoint Files and OneDrive).
If the Internet were a country, it would be the third largest consumer of electricity after China and the United States (Source Ademe)
In 2018, the CSR Platform set up a working group on “Corporate Digital Responsibility” (CDR). It was able to establish new questions and issues on the digital responsibility of companies.
Corporate Digital Responsibility includes the notion of:
The ecological dimension is becoming more and more important in companies.
85% of employees say that companies are able to act in favor of the environmental cause while promoting technological progress.
The ecological transition can take place at all levels and departments of a company: HR, Marketing or IT teams, in charge of all office equipment, data management and security, software and digital tools implemented in the company.
The CRIP has established a barometer  highlighting the desire of 2/3 of CIOs to make responsible digital technology a major issue within their companies, yet collaboration between IT and CSR teams is still weak. As with good security practices for collaborative tools, it remains important to run awareness campaigns among employees on IT eco-actions.
To achieve this, it is important to first adopt individual actions to improve digital sobriety in the exponential use of cloud data.
In order to optimize the loading time of the data, it is possible for a collaborator to put in place some good practices.
The professional emails of a hundred or so employees over a period of one year are equivalent to 13 return trips from Paris to New York (source ADEME).
Documents saved on computers consume a lot of memory and power and can slow it down, especially if they are on the desktop. Each employee should sort and delete data that is no longer needed to save space and avoid keeping unnecessary data.
The digital transition has raised several questions about its ecological impact, particularly with the use of the cloud and collaborative tools. Some organizations are starting to look at their digital and ecological responsibilities.
The giant Microsoft, for example, is working on the Natick project to create underwater data centers to cool their servers in an environmentally friendly way.
On a smaller scale, each employee can participate in the company’s ecological system by keeping in mind good Green IT practices to promote digital sobriety.
