The audit is based on AFNOR Spec 2201 and examines IT resources and their energy consumption throughout their lifecycle, from design and use to decommissioning. It uses more than 130 criteria and assesses both the maturity and environmental impact of digital applications, providing a clear roadmap to enhance sustainability.
Towards a green, sustainable future
GREEN IT: DRIVING SUSTAINABILITY IN THE DIGITAL SECTOR
The ecological transition now touches every sector, with digital technologies accounting for 4–5% of global greenhouse gas emissions. The rapid growth of digital services and the spread of technologies such as IoT and AI are driving greater awareness of the environmental impact of IT.
Green IT promotes a conscious, responsible approach to managing digital resources. For companies, adopting these practices contributes immediately to a more sustainable technology ecosystem.
Besides reducing the ecological footprint, Green IT also delivers economic benefits. When integrated into corporate strategies, it becomes a practical lever for the energy transition.
ECO-DESIGN: THE FOUNDATION OF GREEN IT
Digital emissions primarily stem from two sources: the operation of data and network infrastructures, and the production of technological equipment such as computers, smartphones and other connected devices.
Application development is a key area, which affects natural and digital resource consumption, product lifespan and waste generated over the lifecycle of digital products. Addressing this challenge means rethinking the digital sector from its foundations. Eco-design is a strategic approach that integrates technological efficiency and environmental responsibility into IT projects, helping reduce their overall impact.
An effective Green IT strategy rests on three pillars:
- Understanding, monitoring and reducing the ecological footprint of digital services
- Building an ecosystem of innovators focused on sustainable technology
- Supporting companies in the transition to greener IT through practices such as DevGreenOps and energy measurement tools
Eco-design has become a concrete lever for creating a more responsible, environmentally friendly technological future.
OUR EXPERTISE
Digital service maturity audit
Aims
Evaluate your company’s environmental impact
- Analysing and sizing needs and usage patterns accurately
- Establishing environmental impact thresholds
- Evaluating the contribution of digital services to value creation
- Identifying essential technologies to meet operational requirements
- Formalizing sustainable design processes
- Monitoring, optimizing and correcting the digital ecosystem for maximum efficiency
- Planning end-of-life management for data, components and associated devices
This approach enables the assignment of an “eco-score” to applications, highlights areas for improvement and refines code quality, supporting more sustainable digital development.
Eco-design strategies for digital services
Aims
Develop sustainable applications
The GreenDevOps approach, inspired by DevOps, enhances the environmental efficiency of digital services by measuring and monitoring the ecological impact of applications throughout their lifecycle. Eco-design and digital sobriety principles are applied at every stage of development.
Operational steps include:
- Planning: Raising awareness, training and establishing a shared environmental vision.
- Design: Analysing environmental impact during solution design.
- Growth: Applying eco-design best practices, and writing code according to green coding principles.
- Use: Optimizing energy efficiency and automating scalable resource use.
- Servicing: Assessing environmental impact over time, including static code analysis (e.g., CAST)
- Supervision: Monitoring impact with infrastructure tools (Azure Carbon, FootPrint, Scaphandre, EasyVirt)
- Testing: Conducting dynamic analysis of environmental performance (e.g., Greenspector)
Reference
Eco-design
We propose implementing an eco-design and measurement tool for integrated hardware and software solutions. This approach is being tested in the eco-design of smart sensors used for predictive maintenance on cutting tools in advanced manufacturing environments.
The goal is to optimize industrial processes, prevent failures, extend tool lifespan and reduce energy consumption, with concrete applications in technology-intensive manufacturing and the aerospace sector.
Monitoring the energy impact of digital services
Aims
Control energy efficiency in enterprise software
Cloud adoption and the transition to microservices improve IT resource efficiency by optimizing computing and storage. However, increased service fragmentation can complicate infrastructure, generate more data exchange and increase the distance each request travels, raising energy consumption.
To address this challenge, organizations can rely on technological solutions and monitoring tools to continuously measure the carbon footprint of digital services, detect regressions and act promptly to improve environmental performance.
Green IT training
Aims
Make eco-design a strategic skill
Cloud and infrastructure developers are increasingly trained on the environmental impact of application development and effective eco-design practices.
This training promotes accountability among professionals working in information systems and encourages a sustainable approach to IT.
Trained teams can, in turn, pass on these skills, helping to build a shared culture of digital sustainability and make Green IT a collective responsibility.
