09:40 to 10:30WorkshopSee moreDipping your toes into web sustainability
The World Wide Web Consortium’s Web Sustainability Guidelines offer a comprehensive set of recommendations to make digital products and services better for people and the planet. However, with nearly 100 guidelines including hundreds of success criteria spanning a variety of roles—such as UX designer, web developer, product manager, and so on—they can be quite intimidating to the uninitiated. Knowing where to start is challenging. This workshop will help attendees understand how you can use the Web Sustainability Guidelines in day-to-day digital product work, including roles-based tasks vs. improving general sustainability awareness and education across teams and disciplines. Facilitators will provide suggestions to get started in each category alongside specific examples and case studies. Presentation slidesIn collaboration with

09:30 to 10:00KeynoteSee moreEnvisioning the Web’s green future
The nascent web sustainability movement has grown slowly for over a decade, but climate change and ecological destruction are here now, today. Plus, web sustainability is complicated, requiring a variety of multidisciplinary skills, such as creativity, problem solving, innovation, political advocacy, and technical acumen, to name just a few. It’s easy to get hung up on reducing page size or optimizing images, but how often do we take stock in what success really looks like? What’s our collective vision? How will we get there? Can we create the urgency needed to make progress quickly? How might we align sustainability in tech with broader global goals to improve the world we live in? This interactive session will help us envision what's needed to make web sustainability a reality so we can walk away from GreenIO engaged and inspired to build the web’s green future. Presentation slides10:00 to 10:45KeynoteSee moreOpen source AI for a sustainable future
As AI systems increasingly shape the world we live in, questions around trust, transparency, and ethical impact become ever more crucial. At the heart of these concerns lies a fundamental truth: transparency and accessibility contribute towards sustainability. In this talk, together we will explore why open source isn't just an ideological preference—it's a technical necessity for a more sustainable future for AI. We’ll also break down how open source accelerates innovation, improves security and enables community-driven accountability. From real-world examples to accessible tools and demos, this talk makes the case that open source AI paves the way towards a more resilient and sustainable AI ecosystem.
