"Green" hosting: how to avoid greenwashing
in your cloud choices

In France, digital already represents 4.4% of the national carbon footprint. Globally, it is estimated between 2 and 4% of greenhouse gas emissions and is growing faster than other economic sectors. In this context, the lack of environmental transparency in the cloud has become a regulatory and reputational risk for companies.

Regulatory issue

CSRD, Green Claims Directive, DGCCRF: greenwashing now exposes companies to financial sanctions, non-compliance risks and vulnerabilities in their extra-financial reporting.

A strategic risk for companies

Greenwashing is no longer a matter of image or communication. It has become a legal, financial and regulatory risk for companies.

CSRD: verified environmental reporting

Obligation for verified environmental reporting including Scopes 1, 2 and 3. Scope 3 represents up to 90% of digital footprint, often invisible.

Green Claims Directive (EU)

Prohibition of unproven environmental claims. Sanctions can reach 4% of annual turnover in case of non-compliance.

DGCCRF (France)

Sanctions up to 80% of advertising budget for misleading commercial practices. 15% of controlled establishments had serious shortcomings in 2023-2024.

Scope 3 risk

Choosing an opaque host amounts to transferring a regulatory and reporting risk directly to your company. Scope 3 represents more than 90% of ICT sector emissions.

Frequent non-compliance signals

Audit of environmental communication practices according to Green Claims Directive (EU) 2024/825 criteria. These findings are derived from cross-analysis of supplier communications, public reports and Directive (EU) 2024/825 criteria.

Non-compliance Article 3.1 Green Claims Directive

Unverifiable communication

Generic claims without proof of recognized excellent environmental performance

Observed examples:

  • "Committed to the environment"
  • "Responsible cloud"
  • "Green solution"
  • → No published metrics
Non-compliance Article 3.4 Green Claims Directive

Absence of technical data

No PUE per site, no CUE, no published Scope 3

Observed examples:

  • No PUE per site
  • No CUE
  • No Scope 3
  • → Non-verifiable data
Non-compliance Article 3.2 Green Claims Directive

Carbon neutrality based on offsetting

Claims of neutral impact based solely on offsetting emissions

Observed examples:

  • "Carbon neutral"
  • "Net zero"
  • → Practice explicitly regulated and restricted by Directive (EU) 2024/825

Checklist: what your host must be able to provide

If any of these elements are missing, the greenwashing risk is real. This checklist can be copied, printed and used in calls for tenders. This checklist aims to help companies assess a supplier's transparency. It does not constitute a certification or labeling.

Frequently Asked Questions

Everything you need to know about green hosting and greenwashing

Greenwashing exposes companies to several risks: CSRD (obligation for verified Scope 1, 2, 3 reporting), EU Green Claims Directive (sanctions up to 4% of turnover), DGCCRF France (sanctions up to 80% of advertising budget). Choosing an opaque host = transferring a risk to your own reporting. Scope 3 represents more than 90% of ICT emissions.
Verifiable checklist: PUE measured per site and per year (≤ 1.3), CUE published (gCO₂e/kWh IT, target < 50 g), WUE published (L/kWh IT, target < 0.10 L), public GHG report (Scopes 1, 2, 3), documented methodology, traceable energy mix (France/EU), no claim based solely on offsetting. If any element is missing, the greenwashing risk is real.
PUE (Power Usage Effectiveness) = energy efficiency (total energy / IT energy). Target: ≤ 1.3. CUE (Carbon Usage Effectiveness) = CO₂ emissions per kWh IT. Target: < 50 g CO₂e/kWh IT. WUE (Water Usage Effectiveness) = water consumption per kWh IT. Target: < 0.10 L/kWh IT. These indicators must be published per site and per year.
Scope 3 represents more than 90% of ICT sector emissions (equipment manufacturing, client networks). A host that does not publish its Scope 3 exposes you to CSRD non-compliance risk. Your reporting depends on your host's transparency. Require a complete GHG report including Scopes 1, 2 and 3.
Yes, Directive (EU) 2024/825 prohibits claiming that a product has a neutral climate impact based solely on offsetting emissions. Claims based solely on offsetting are non-compliant. Prefer hosts that publish real reductions (low PUE, direct renewable energy) rather than offsets.
In France, DGCCRF can impose fines up to 80% of advertising budget for misleading commercial practices. 15% of controlled establishments in 2023-2024 had serious shortcomings. The Green Claims Directive provides for sanctions up to 4% of annual turnover. Reputational and climate litigation risk is also increasing.
Require: PUE, CUE, WUE published per site and per year, complete GHG report (Scopes 1, 2, 3) with documented methodology, traceable energy mix (volumes per site, GO copies, PPA summary), documented client allocation approach. If this data is not publicly available or on request, the greenwashing risk is real.
FileVert publishes what can be verified: French hosting (Scaleway), PUE 1.1-1.3, low-carbon electricity mix, traceable data. FileVert does not promise carbon neutrality. Data is published or accessible, with documented methodology. Verifiable approach, not declarative.
