En bref : La réduction des émissions est une priorité qui prend de l’importance pour de nombreux pays et industries, et l’informatique n’est pas épargnée. Ce guide couvre : Les avantages des pratiques Green IT du point de vue des entreprises, Réduction des coûts opérationnels, Atténuation des risques, Une opportunité de se démarquer de la concurrence.
Reducing emissions is a priority that is becoming increasingly important for many countries and industries, and the IT sector is no exception.
In this article, we will focus on the role of Green IT not only in creating sustainable web and mobile applications, but also in the success of companies that must address environmental challenges with ingenuity in order to remain relevant and increase their efficiency on multiple levels.
What is Green IT?
Green IT refers to more environmentally-friendly computing practices, aimed above all at minimizing the energy consumption of our digital tools and software.
To explore this further, there are two ways to use digital technology:
- On-site, local use of your computers and servers.
- The use of web services and "cloud" services, which operate using remote servers.
Although digital products may seem significantly less polluting than physical ones, numerous studies show just how much the digital world contributes to GHG emissions—and this impact is far from negligible!
According to a study by Frédéric Bourdage, an expert in digital sustainability and founder of the website GreenIT.fr, the carbon footprint associated with digital activities is estimated to account for about 5% of total global emissions, or approximately 2 gigatons of CO2.
According to the Senate’s preliminary report from the fact-finding mission on the digital sector’s environmental footprint, GHG emissions from the digital sector could increase significantly if no action is taken to reduce its footprint: a 60% increase by 2040, representing 6.7% of national GHG emissions.
Digital emissions are broken down as follows (according to a study by the Green IT Think Tank):
- User Equipment (66%)
- Networks (19%)
- Data centers (15%)
When it comes to software development, Green IT focuses on reducing emissions by easing the load on networks and data centers.
The Fundamental Principles of Green IT in Software Development
In practice, Green IT in 2024 generally takes the form of the following strategies:
Writing Efficient Code
One of the key elements of Green IT is writing energy-efficient code that minimizes the resources required to run software applications.
By optimizing algorithms and reducing computational complexity, developers can create a digital product that consumes less energy and generates less heat, thereby contributing to a smaller carbon footprint.
In addition, minimizing the use of memory-intensive processes and eliminating redundant code can further improve energy efficiency.
Reduction of Internal Infrastructure
Cloud service providers often have infrastructure that is highly optimized for energy efficiency.
By migrating to cloud-based services, companies can minimize their need for on-premises infrastructure while benefiting from energy efficiency and sustainable practices.
This not only minimizes the costs and complexity associated with managing infrastructure, but also allows us to benefit from the energy efficiency and sustainable practices of these data centers. For example, our partner DRI offers eco-friendly web hosting through its innovative green data center in France, which has a PUE of 1.15.
Test Automation / Green IT Testing
Testing tools are another eco-friendly practice that is not only environmentally friendly in and of itself—by identifying bugs as efficiently as possible—but can also help identify areas where your software solutions can be improved from an environmental standpoint through Green IT automated testing.
Automated testing offers several benefits in terms of digital sustainability:
Product lifecycle optimization: By detecting and fixing bugs more quickly, organizations reduce the waste of resources associated with fixing defects at advanced stages of development.
Reducing carbon emissions: Manual testing requires extensive hardware and energy infrastructure. Test automation enables companies to significantly reduce their energy consumption and, consequently, their carbon emissions.
Assessing the status of your development practices and software to identify areas for improvement: Regular Green IT testing can provide essential insights into the current state of your digital infrastructure as well as the success of your Green IT initiatives, allowing you to refine your strategies over time.
Green IT Monitoring
Green IT monitoring involves conducting Green IT tests on an ongoing basis. Tracking the digital footprint over time allows organizations to remain constantly aware of areas that can be improved at any time.
It is possible to achieve better results before carrying out an update that is ineffective from an environmental standpoint, and to remain unaware of the problem until it causes damage.
For example, at Mr Suricate, Green IT monitoring provides you with the following key KPIs:
- The size of the resources
- The number of requests
- The number of elements in the DOM
- Greenhouse gas emissions
- Water consumption
The Benefits of Green IT Practices from a Business Perspective
Adopting Green IT is not only beneficial for the environment, but also for several aspects of business:
Reduction in Operating Costs
Companies can significantly reduce their energy consumption and associated costs by adopting a greener infrastructure.
According to a study conducted by Boavizta, an organization dedicated to assessing the environmental impacts of digital technology, among organizations that report cost savings from Green IT practices, one in three cites reduced IT purchases, and fewer than one in four cites lower energy bills.
In the study, video game publisher Ubisoft cites potential savings of “more than 1 M€ per year by putting workstations into sleep mode and extending the lifespan of equipment.”
Risk Mitigation
Adopting sustainable practices helps companies comply with environmental regulations and avoid potential fines or legal issues.
It also reduces the likelihood of negative publicity…
An opportunity to stand out from the competition
By adopting sustainable practices associated with Green IT, companies can position themselves as leaders in the green industry, fostering a positive image that attracts customers and partners who are increasingly prioritizing environmental responsibility.
One way to promote Green IT initiatives is through case studies and success stories that highlight the concrete environmental benefits of completed projects.
A development process focused on efficiency
Sustainable practices drive innovation as companies seek new ways to optimize processes and reduce waste, which inevitably leads to the development of more effective software solutions.
