Practice · Cost & carbon performanceThe situation
Two pressures, a single cause
Your cloud bill is rising faster than your business, and AI usage is accelerating the movement. At the same time, you are being asked to account for the environmental footprint of your information system.
Most organisations handle these two subjects separately: two data sets, two timetables, two action plans that never speak to each other. That is wasteful, for three reasons.
The methods are the same
Identify the drivers, measure, allocate, decide. The analytical work is rigorously identical.
The results point the same way
Reducing emissions most often amounts to reducing costs.
The environmental argument carries the financial plan
A cost-reduction exercise meets resistance that a sufficiency exercise meets far less.
Our method
The Cigref model and top-down analysis
We work from the economic and environmental IT management model published by Cigref, the French association of large-company CIOs, which structures the analysis of IT costs and their correlation with environmental impact. Top-down analysis then ranks the levers against your strategic objectives, rather than against what is easiest to measure.
Our tools connect your consumption data, your IT budget and your emissions. Where a conventional audit produces a snapshot, this approach produces a dashboard you keep using after we leave.
Three methodological innovations
Delivered through Esiense Carbon.
Levels of engagement
Three entry points, from assessment to governance
Indicative durations. Pricing is established case by case, in a meeting.
01
Cost-carbon review 5 days
Your budget is slipping, or a reporting obligation is arriving. Collection of cost and consumption data, application of the Cigref model, top-down analysis of the drivers, identification of quick-return levers.
You leave with
- Your cost structure and your emissions structure set side by side
- Three to five levers costed in euros and in tonnes of CO2e
- An estimate of the twelve-month gain
02
Optimisation plan 15 to 20 days
Detailed audit, quantification of the levers, arbitration, multi-year trajectory, integration into procurement and project governance processes.
You leave with
- The full audit
- A prioritised, costed action plan
- A management dashboard
- Environmental criteria for your tenders
03
Green PMO 6 to 24 months registered trademark
The PMO orchestrates project governance. We have extended its scope to environmental matters: sufficiency built into the management of projects, procurement and IT strategy.
You leave with
- Governance that runs
- A trained PMO team
- A deliverable describing what your teams can do on their own
On regulatory pressure
We would rather tell you where you actually stand
The landscape is moving fast. Non-financial reporting obligations have been substantially reworked, and the set of companies concerned is no longer the one initially announced.
Rather than sell you an urgency that may not apply to you.
AI in this practice
AI is a line of spend and emissions like any other
Footprint of AI usage
Training, inference, corpus storage: we attach this consumption to your digital services, using the same method as the rest of your IT.
Decide before you commit
An AI use case is decided like a project: total cost, footprint, expected gain. Green PMO puts it on your governance agenda rather than in a year-end report.
Continuous measurement
Esiense Carbon turns what was measured once a year into something continuous, and tracks the real effect of the actions taken.

Lead partner
Nicolas Ludmann
Partner, programme director
He defined the service catalogue of an international industrial group's private cloud, then took charge of its governance, its chargeback and its carbon footprint.
In a listed group, he led the reduction of infrastructure costs across an international perimeter.
On an interim management assignment, he reorganised a PMO team responsible for a portfolio of several hundred projects, then handed responsibility to an internal manager. Accredited trainer, IHEDN auditor.
