Green IO Amsterdam 2026: Measurement, Method, and Meaningful Action

Green IO Amsterdam 2026 took place 9–10 June 2026 at Tolhuistuin — the Benelux stop on Green IO’s 2026 tour, between New York in May and Munich in July.

With 150+ responsible technologists from five countries, Amsterdam offered a deliberately European counterpoint to the AI hype cycle: less manifesto, more method. The programme asked which GreenOps practices replicate, which tools earn adoption, and when local Dutch agility beats waiting for harmonised standards.

Amsterdam’s angle: from carbon cargo cult to organisational impact

The opening workshop set the tone. Tom Moran (Colt Technology Services) unpacked “The Cascading Cognitive Calamity of the Carbon Cargo Cult” — why optimising solely for carbon misdirects decisions, ignores water stress and grid constraints, and compounds mitigation-only thinking in the AI boom.

That framing echoed through the two days: measurement without shared definitions, transparent supplier data, and leadership accountability rarely changes anything meaningful.

Workshop highlights — 9 June

• Measuring the IT carbon footprint: from method to meaningful action — aligning methods and data points across organisations and borders (Conclusion, ABN AMRO)
• TNO & Resilio — the Netherlands ICT and AI footprint — national-scale footprint assessment with live tooling
• CED’s IT CO₂ plan — community sponsor pitches from Dutch sustainability initiatives
• Green coding with GitHub Actions — practical CI integration for developer workflows

Conference highlights — 10 June

Day two mixed provocation with operational detail:

• Learning how to scale from Dutch resistance during WWII — an unconventional opening on organisational resilience
• The digital future is degrowth — challenging growth assumptions baked into digital product roadmaps
• Embedding GreenOps in practice — from framework slides to organisational impact
• KEIT, one year on — measuring Kubernetes carbon on a sovereign cloud
• Procurement as a lever — creating market demand for sustainable IT through buying power
• Scaling GenAI and carbon at Rabobank — a bank’s journey and key learnings one year into deployment
• The human side of AI-generated code — where LLM-assisted development meets sustainability trade-offs

Amsterdam’s programme reflected the Netherlands’ particular strength: frank cross-sector conversation between banks, research institutes (TNO), and practitioners who have been measuring ICT emissions longer than most European peers.

Green IO Amsterdam ran within the Future Of Software Technologies federation at Tolhuistuin — the same venue ecosystem that hosts Apidays and related independent tech conferences. For attendees already in Amsterdam for API or platform engineering topics, Green IO was the sustainability track with the deepest practitioner bench in the Benelux.
