Green IO is the conference for technology leaders who are serious about making IT sustainable — not as a PR exercise, but as an engineering and operational discipline. The 2026 Amsterdam edition arrives at a pivotal moment: generative AI is exploding energy demand across data centres, while European climate policy faces headwinds and tech giants tighten their grip on infrastructure. Green IO responds with high-quality technical sessions — latest research, real-world case studies, deep dives into responsible AI, green software engineering, carbon-aware stacks, green cloud architecture and sustainable hardware. The 150+ attendees are practitioners: engineers, architects, sustainability leads and executives genuinely trying to reconcile performance with planetary cost. Part of the Future of Software Technology conference at Tolhuistuin.
