Today we are publishing our 2026 Sustainability Report, covering the full calendar year 2025 across all our data centre regions and offices. The headline: we reduced absolute scope 2 emissions by 34 percent while growing compute capacity by over 60 percent.
Key figures
- 100% renewable electricity across all Swiss and EU data centre operations
- 34% reduction in absolute scope 2 emissions year over year
- Average PUE of 1.18 across owned facilities, down from 1.26
- Waste heat from our Zürich facility now warms 400 nearby apartments
Where we fell short
Transparency requires reporting misses alongside wins. Our scope 3 supplier emissions remain an estimate rather than a measurement for 40 percent of our vendor base, and our target of full measurement by end of 2025 slipped to mid-2026. Business travel emissions also rose 12 percent as in-person customer work rebounded — we have introduced a per-team travel carbon budget for 2026 to bring this back in line.
The full 48-page report, including our methodology and third-party assurance statement, is available for download. We welcome scrutiny: sustainability claims in our industry too often evaporate under inspection, and the only remedy is publishing numbers someone else can check.
