An example
This could be your situation.
Take one company as an example: three sites, three spreadsheets, no shared answer.
Nobody can consolidate.
Nordhavn Industries, 2,400 people in Hamburg, Lyon and Porto. A client asks where the group stands. Each site answers in its own spreadsheet, with its own scales.
Three weeks, a single base.
One Sustainable IT maturity framework (Green IT, IT for Green, digital service eco-design) assessment launched across all three sites at once, from the managers’ interview notes. The framework was already written, its 10 themes and levels L1 to L5 too.
Two costs avoided before being committed.
A score of 53 out of 100, with the gap concentrated on three themes. The AI companion spotted that two actions duplicated those of another audit. The committee report took one sentence to request.
What it saved them
- 3sites measured on the same base, instead of three questionnaires to reconcile
- 2duplicate actions caught before the spend
- 1committee report, with no manual rework
These figures are an example. They could be yours.
The standard imposes processes. Datamensio says where you stand.
01
The framework is already written
Themes, questions and levels L1 to L5, all written. You do not start from an empty spreadsheet.
02
The score lands the same day
Online, by self-assessment link or in interview. Theme by theme, comparable over time.
03
The gap becomes a costed plan
Every step up carries its action. The AI prioritises on expected effect, not on the order of the standard.
04
Progress can be demonstrated
Campaign after campaign, against your target and against your own past. That is what your board asks for.
The maturity scale
One level, the next, and the action that links the two.
This mechanism, a level, a level above, and the action that connects the two, is what turns an observation into a trajectory.
Are eco-design criteria built into the life cycle of digital projects?
- N1
No environmental criterion features in digital projects. The subject is not raised during appraisal.
- N2
A few teams apply good practices on their own initiative. Nothing is formalised or shared across projects.
- N3
Eco-design criteria are documented and applied on significant projects. Gaps remain occasional and are explained.
- N4
Criteria determine whether project milestones are passed. Weight and consumption measurements are logged and reviewed before go-live.
- N5
Criteria are revised based on actual measurements in production and lessons learned, with a documented record of revisions and thresholds.
Action to move from L2 to L3
Formalise a short list of eco-design criteria, build it into the project appraisal file and have it reviewed at the existing architecture committee, starting with next quarter’s projects.

What this framework covers
Sustainable IT brings together three distinct families of practice. Green IT reduces the footprint of the information system itself: device lifespan, reuse rates, energy efficiency of server rooms and the cloud, and the sobriety of software architectures. IT for Green puts digital technology to work for the organisation’s environmental goals: measuring consumption, optimising logistics, and managing environmental data. Eco-design treats the digital service as a product whose life cycle is managed, from design to decommissioning.
In practice, these areas are hard to steer because responsibility is scattered across several departments. Who actually knows the average age of the fleet and where it ends up? Is cloud consumption tied to identified services, or lost in a single bill? Do application projects factor in an environmental criterion at appraisal stage, or only in the rhetoric? Most organisations have public commitments and one-off initiatives, but no mechanism for stating what level of control they have actually reached.
The context has fundamentally changed. The CSRD directive, with the ESRS standards, requires environmental data that is substantiated and auditable, and digital technology contributes on two fronts: as a source of impact and as a source of the data itself. In France, the general framework for eco-designing digital services and the REEN law have established a shared vocabulary. The common confusion remains the same: offsetting is not reducing, and a well-written non-financial report says nothing about the actual level of engineering practice.
The maturity assessment answers a different question than reporting does. Reporting asks: what are your indicators and are they substantiated. The assessment asks: what level of control does each practice sit at, and what specific action moves it to the next level. This is what allows two business units to be compared, one’s own progress to be tracked over time, and investments to be prioritised rather than multiplying initiatives.
In Datamensio, the framework is ready to use and remains yours. The AI adjusts the themes, questions and levels to your sector and fleet size, or builds a variant from your own documents: sustainable IT policy, IT master plan, equipment inventory.
Reference standard: Sustainable IT maturity framework (Green IT, IT for Green, digital service eco-design)
The themes assessed
Sustainable IT strategy and governance
Formalised policy, alignment with the organisation’s environmental strategy, roles and responsibilities, dedicated budget, committee-level decisions.
Measuring the footprint of the information system
Scope covered, method used, distinction between manufacturing and use, sources of emission factors, refresh frequency, data reliability.
Equipment life cycle
Fleet inventory, service life, repair and refurbishment, internal reuse, end-of-life channels, traceability of disposals.
Data centres and hosting

Indicators tracked, alignment with non-financial reporting, periodic reviews, comparison over time and between entities, incorporation of lessons learned.
A short version of the framework is available for the online self-assessment.
Frequently asked questions
Is sustainable IT subject to certification?
No body certifies an organisation as "sustainable IT" against a single standard. The subject is managed as a transformation effort: an observed maturity level, a target, a roadmap. Datamensio measures and prepares the decisions, it issues no label.
What is the difference between this assessment and a carbon footprint of the IT estate?
The carbon footprint produces a volume of emissions at a given date. The maturity assessment qualifies the practices that produce those emissions and those that will reduce them. The two complement each other: the measurement gives the order of magnitude, the assessment gives the levers and their sequence.
How long does the assessment take?
The short version takes 20 to 30 minutes for someone who knows the SI to complete. The full version involves several contributors, IT, procurement, CSR, architecture, and generally spans one to two weeks, most of the time going into gathering input from the teams.
Can the framework be adapted to our context?
Yes. The themes, questions and level wording can all be changed, and you can add your own axes. The AI suggests variants by sector or fleet type, and can build a version from your internal policy.
How do we compare several business units?
The same framework is rolled out to each entity, which makes scores comparable by theme. A cross-entity roadmap consolidates the assessments and groups recurring actions, rather than treating each entity in isolation.
Does this assessment support CSRD reporting?
It does not replace reporting, but it feeds its qualitative component: state of practices, action plans, governance. It also highlights environmental data that is missing or not reliable enough to publish.
Do respondents need technical expertise?
The questions cover management and engineering practices, not configurations. Some require input from an architect or operations manager: the collaborative mode allows these questions to be assigned to the right person.
Where is the data hosted?
In France, with OVH, backed up at Scaleway. No transfer outside the European Union. The AI models used can be selected, including from European providers.
