Green IT: cut your IT footprint and IT costs

Green IT — also called Sustainable IT — means measuring and then reducing the environmental footprint of your information system, while removing the extra costs caused by IT bloat.

What is Green IT?

Green IT covers the practices that reduce the environmental footprint of digital technology: the manufacturing, use and end of life of IT equipment, but also software usage and employee culture.

Sustainable IT and digital sustainability describe the same thing. The vocabulary differs; the approach does not — measure, decide, act, report.

Why Green IT also cuts your IT costs

IT equipment accounts for a significant share of a company's environmental footprint. The same root causes — oversized devices, dormant hardware, over-frequent refresh cycles, unused licences — generate both emissions and unnecessary spend.

Tackling IT bloat therefore reduces your IT footprint and your IT costs at the same time, while improving environmental reporting and its regulatory alignment.

How a Green IT audit works

A Green IT audit assesses the footprint of your IT estate and the maturity level of your teams. It typically takes 2 to 4 weeks depending on the nature and complexity of the estate.

1. Data collection
Inventory, usage and practices. This is the most time-consuming step: we help you gather complete, usable data.
2. Footprint measurement
Footprint of manufacturing, use and end of life of your equipment, and identification of the heaviest contributors.
3. Maturity and culture
Assessment of your teams' Green IT maturity and of the blockers in your internal culture.
4. Action plan
A tailored action plan built on SMART objectives and precise indicators, ready to distribute department by department.

Green IT frequently asked questions

What is a Green IT strategy and where do I start?: A Green IT strategy involves assessing your footprint, then planning and implementing actions to reduce your digital footprint and raise your Sustainable IT maturity. The usual first step is an environmental audit of your information system, to understand the strengths and improvement opportunities of your existing infrastructure and culture.
How long does it take to roll out a Green IT strategy?: It depends on company size, infrastructure complexity, available resources and employee culture. As a rule, defining the strategy, implementing it and obtaining results takes from a few months to a year.
What kind of actions does a Green IT strategy include?: Green IT strategies include actions on governance, employee awareness and training, stakeholder engagement, internal and external communication, and the purchase and management of hardware and software.
What improvements can a Green IT audit deliver?: A Green IT action plan reduces the environmental footprint of your IT estate, lowers its financial cost by removing IT bloat, improves the company's Green IT culture and positions the company as a reference in its sector.
What is the difference between digital eco-design and web eco-design?: Digital eco-design means designing digital services while limiting their resource consumption across their whole life cycle. Web eco-design applies this to websites and web applications: lighter pages, restrained media, fewer requests and lower server load. Both belong to a Green IT approach and combine well with digital accessibility.
Are digital accessibility and web accessibility part of Sustainable IT?: Yes. Digital accessibility — of which web accessibility is the most visible part — ensures your services can be used by everyone, including people with disabilities. It is the social component of Sustainable IT, alongside the environmental component covered by Green IT.
What are the ISO 14040 and ISO 14044 standards?: ISO 14040 and ISO 14044 are the international life cycle assessment (LCA) standards: ISO 14040 sets the principles and framework, ISO 14044 the requirements and guidelines. They provide the methodological reference for assessing the environmental footprint of a product or service, including digital ones.
