The executive committee approves "migration to Finland" for carbon neutrality. The vendor cites Nordic green power and free cooling. Nobody asked whether new servers emit more than cooling savings compensate — or whether the CDN stays American.
Nordic helps; it does not certify.
Why the north attracts green messaging
Low-carbon power mix (hydro, nuclear, wind by country), climate suited to free cooling, CSR image of "cold datacenter", players like atNorth, Google eu-north, Hetzner Helsinki, UpCloud. Our PUE communication investigation and Green hosting guide frame the reading.
| Claim | Verification |

| 100% renewable | PPA contract or grid mix? |
| PUE 1.1 | Annual measured or marketing? |
| Carbon neutral | Offset vs reduction? |
| Nordic green | Scope 3 hardware included? |
A carbon report without perimeter is opinion — not proof.
Due diligence grid
PUE: annually measured value, not marketing snapshot. ERE/ERF: reused heat (Helsinki, Stockholm district networks). Scope 3: server manufacturing, DC construction. Hardware: lifespan, refurbishment. Water: evaporative cooling? Client side: your stack — CDN, assets, CI.
Nordic vs other green EU
Sweden and Finland win on power mix. Switzerland (Infomaniak) or France (OVHcloud eco A) can compete if figures are complete. Compare the directory ecology filter — not latitude flag.
The climax: green infra, grey application

Request the host's dated carbon report and measure application performance in parallel. Build a short list of two Nordic providers plus one documented European comparator. Use the compare tool and green guides on the same indicator grid.
Frequently asked questions
Nordic datacenter automatically green?
No — require PUE, Scope 3, dated proof. Cold climate and power mix help but do not replace documented footprint.
Which indicators to require?
Annual PUE, renewable share, Scope 1-2-3, heat reuse, hardware policy. Reject slogans without quantified perimeter.
Does it reduce my site's footprint?
Infrastructure yes; application, CDN, and third-party SaaS often outside the DC. Nordic choice does not offset a heavy application stack.
Compare two green Nordic hosts?
Same grid: public report, third-party audit, cooling, hardware — not logo alone.
A sustainable Nordic datacenter is read in the carbon PDF — not in outdoor temperature.
