Why they attended our past editions

“It’s a great place to learn from you peers [...] and it’s great energy to surrounded by people as passionate about the topic as I am”

Venetia FOO, Sustainability Lead (Palo IT)

"Attending the Green IO conference is an absolute must for anyone passionate about sustainable IT. It’s the perfect place to discover cutting-edge tools, proven best practices, and practical strategies to effectively measure and minimize your IT environmental impact."

Pierre Seroul,Head of Data & Energy Efficiency Domain (Eviden)

What makes GreenIO special is how it bridges the gap between the technical realm and the climate crisis. As a designer, I was surprised to find myself riveted by even the most esoteric and technical topics. The quality of the speakers and the breadth of content were exceptional.

James Christie, User Experience Director (SustaianbleUX)

“It was really cool to interact with such a great, international audience which was very focused on the topic at hand. The talks were amazing! I'm looking forward to the next edition.”
