Workshop Day
Wednesday 30th September 2026
09:00 to 09:30Welcome Breakfast — Partners Village
09:30 to 09:55WorkshopSee moreDigital Impacts Schema and Taxonomy Workshop
Organisations can measure the carbon footprints of their technology with increasing confidence, but carbon is only one dimension of technology's impact on the world. Water consumption, electronic waste, biodiversity loss, supply chain conditions, and the societal and individual harms caused by technology systems are all material impacts. Today there is no consistent, open, structured way for organisations to report on or share data about these impacts alongside their carbon data. Help be part of the definition of that standard in this workshop! Presentation slidesIn collaboration with
09:55 to 10:20WorkshopSee moreScaling Sustainable IT & AI: Trust, Efficiency & ROI , via a Native Module ServiceNow

10:50 to 11:15WorkshopSee moreWhat does AI emissions data look like in 2026?
AI emissions are still a black box. Providers expose different usage data, infrastructure is hidden, and there's no single standard for turning AI activity into a meaningful emissions number. This session shows what AI emissions data can look like in 2026: how token usage translates into estimates of energy, carbon and water, and one consistent methodology applied across AI providers, SaaS tools and agents. We'll see how this data drives better AI decisions and cuts cost and emissions, then bring it to life with a live demo: the footprint of a Claude Code prompt, calculated on stage.

11:15 to 11:40WorkshopSee moreAI, ally or enemy of the planet?
Today, no one really knows the energy consumption, carbon emissions or water consumption of AI models. This lack of transparency throughout the ICT supply chain poses a real problem for businesses that are exposed to supply-chain-related economic risks. Resilio is leading a collaborative study, involving academics, private and public organisations, and institutions, with the aim of raising awareness of the environmental impacts of AI, quantifying them, and turning this environmental information into a management and governance tool. Presentation slidesIn collaboration with
11:40 to 12:05WorkshopSee moreMeasured is not managed: what an IT estate looks like once the levers suggest themselves
FinOps, asset management, workplace, observability and carbon platforms each answer the question they were bought for, and none of them tells you where the largest gains sit across the whole estate. This workshop shows what it takes to see that in one place: a ranked list of optimisation levers, the cost and CO2 gain behind each, the complexity of doing it, and a simulation of the combined result before you commit. Presentation slidesIn collaboration with
12:05 to 12:30WorkshopSee moreFree Greenpixie Data Now Available
The subject of cloud carbon emissions has long been a black box. Actionable, accurate data for unified cost and carbon optimisation is a dream that many engineers, FinOps practitioners, and IT leaders have given up on. Until now. Greenpixie's research team is releasing all its carbon data for AWS, Azure and GCP compute usage; so every forecast, optimisation, migration, modernisation and architecture design, can now feature carbon alongside cost, performance and security considerations. That's good news for those who believe technology and sustainability are better together. Hear how you can start using Greenpixie's industry-leading compute emissions data free today and what GreenOps experts like Synyega are already building on top of the free tier.

Conference Day
Thursday 1st October 2026
09:00 to 09:30Welcome Breakfast — Partners Village
09:30 to 09:45OPENING REMARKSSee moreOpening remarks
Somewhere in the last three years, writing code became an energy decision. Not figuratively. A model choice is a power draw. A retry policy is a power draw. A default context window, shipped once and forgotten, is a power draw repeated millions of times a day. None of that used to be ours to decide, and most of us missed the handover. That is Follow the energy. Over two days at Convene Sancroft we trace one watt from the grid, where a connection queue decides what gets built, through the data centre, into the codebase, up to the board. Everyone here holds a piece of it: sustainability experts working on procurement and decarbonisation plans, Tech practitioners working on GreenOps and AI right-sizing. Some of us will flatly disagree this week, which is rather the point of a room. Responsible technologists do not need another warning. We need numbers, levers and someone who has tried it. Thank you to the speakers, partners and volunteers who brought them. Welcome back.09:45 to 10:20KeynoteSee moreCan offshore wind power the AI boom?
Deployment of offshore wind has accelerated over the last two decades but needs to increase pace and scale of deployment to meet mid-century net zero targets. I will explore how the AI boom is adding to the demand for decarbonised electricity and the opportunities for the offshore wind sector to respond through technology and policy for responsible, sustainable solutions. As two relatively new kids on the block, I will set out the supply and demand of offshore wind and AI in the broader societal and energy context. I will debunk some myths and shine a light on the risk of inaction for us to decarbonise and to ensure we stay on the leading edge of both offshore wind and AI. Presentation slides10:20 to 10:45TalkSee morePeople-powered progress: OVO’s collaborative blueprint for responsible AI use
As a UK energy retailer with ambitious net-zero targets, OVO’s strength lies in our mission-driven team. When we introduced AI as a key tool to accelerate innovation as part of this year's targets, we knew we needed to start an open dialogue with our teams to ensure its use aligned with our shared values. This led to a journey where Tech & Sustainability teams partnered with people across our offices. Through collaborative workshops, we aim to transform initial concerns into a co-created strategy. This is how we’re harnessing technology and teamwork to build a more sustainable future. Presentation slides10:45 to 11:10TalkSee moreFrom Principles to Standards: A Journey Toward Energy-Aware Streaming
What does it take to turn real-time energy measurements into actionable information across a complex value chain? Using video streaming as a use case, this session explores how an emerging technical need can enter the standardization landscape. Energy is only one part of the picture: measurements must be trustworthy, verifiable, secure and attributable across different stakeholders. With communities and SDOs looking at different pieces, the challenge is finding common ground through openness, collaboration and consensus—and exploring what can, and should, become a standard. Presentation slides11:10 to 11:30Coffee Break & Networking — Partners Village
11:30 to 12:15Panel DiscussionSee moreGreenOps Customer Showcase Panel
How to Unlock the Double-Wins of AI and Cloud Sustainability. Using real-life case studies, this session explores how enterprise customers can deliver on the promise of business value and address IT Sustainability goals. How to support the demands of Responsible AI, FinOps and Tokenomics programs. An opportunity to learn directly from practitioners from both the public and private sector. Presentation slides12:15 to 12:40TalkSee moreYou already have what you need: Open Source GreenOps in Practice
The environmental impact of cloud computing is surging, driven by AI workloads. While FinOps is now standard practice, its green counterpart—GreenOps—struggles due to a lack of transparent sustainability data from cloud providers. This talk introduces SPRUCE, an open-source platform built on Apache Spark to operationalise GreenOps at scale, enriching cloud usage data to quantify environmental impact and surface actionable insights. In the second part, Diana will explain how she built GreenOps dashboards from SPRUCE data using open source observability tools. She will also talk about related efforts in the ecosystem. Presentation slides12:40 to 13:05TalkSee moreDeveloping the world's first sustainability certification for cloud resources
As cloud adoption accelerates, organizations need practical ways to procure cloud resources more sustainably and to measure and report on their impacts. To address this need, TCO Development has developed TCO Certified Cloud, the world's first sustainability certification for cloud resources, with independently verified criteria covering climate, circularity, chemicals, supply chains and transparency. The first certifications are currently being piloted, with certified cloud resources expected in Q4 2026. The talk will share key insights from this journey and the future developments ahead.

14:10 to 14:35TalkSee moreGreen Agentic AI: Optimizing Cost, Energy and Carbon
Agentic AI can consume orders of magnitude more compute than a simple chat interaction, making efficiency a design requirement, not an afterthought. This session introduces Green Agentic AI: how to measure cost, energy, carbon and water per task, then systematically drive them down. Using SCI for AI, emerging SEI and SWI metrics, and a six-stage agent lifecycle, the session shows the design levers across models, context, tools, retries, memory and scheduling, grounded in GSF standards and a practical Monday-morning checklist. Presentation slides14:35 to 15:00TalkSee moreLeading Sustainable AI from Strategy to Scale
Drawing on experience leading a pioneering customer-facing agentic AI proposition in UK banking, this session explores moving from strategy to production while scaling AI without scaling environmental impact. I will cover proportionate model selection, reducing computational waste, and embedding responsibility throughout the AI lifecycle. Attendees will learn to connect environmental responsibility with engineering efficiency, moving beyond governance checkpoints to continuous leadership commitments for sustainable, trusted AI. Presentation slides15:25 to 16:00Coffee Break & Networking — Partners Village
16:00 to 16:25TalkSee moreConsidering Your Personal Energy Flow; AI Sustainability Actions you can Take
In response to the conference theme “Follow the Energy” , GDS Digital Sustainability Lead Emma Albury calls for greater consideration of energy expenditure - both technological and personal energy. Cutting through the AI hype she asks “Why are we using AI? What is worthy of our energy?” and “How can we use our energy more sustainably?". This is a call for action as a tactic to combat the climate and AI doom many of us face and instead, she offers hope using government case studies and practical tips to exemplify “good” AI use and purposeful use of energy. Presentation slides16:25 to 16:50TalkSee moreFractional Influence - everyday 'greening' as a contractor in tech
In a fragmented tech workplace how might an ethical contractor make a difference? As a technologist and researcher who transitioned into UX, I found myself in a pickle. No one was hiring researchers because LLMs made code cheap. So, I became a part-time product manager. As a PM, I realised that I had an opportunity to make a difference to digital sustainability with my small business clients. From little things like tagging tickets for ‘sustainability’, content formats, UI design, and token use. To strategic decisions such as hyperscalers, compute, and grant funding. Presentation slides

Why they attended our past London editions
“Thanks again for inviting me to join the panel discussion at GreenIO. The energy and passion in the room was brimming which is always very encouraging! Great job on such a successful event.”
Lydia Tabbron, Digital Sustainability Lead (DEFRA)“This was my second year at Green IO and I was so honoured to be on stage for a second year as well and the growth, and bigger stage! gave me goosebumps. I walked away inspired and having learnt things that we’ll be applying to our own digital sustainability projects. But mainly the sense of community that I felt at the conference was incredible and uplifting and it has inspired me to reignite getting more involved in the wider digital sustainability community as well.”
Andri Johnston, Digital Sustainability Lead (Cambridge University Press and Assessment)“I’m not new to sustainability, yet I am fairly new to finding like-minded people to talk to about it. My entry points were my local Green Software and GreenSEO meetup groups. So, coming to Green IO, I knew there were some good speakers, but I didn’t know what to expect in terms of vibe. How brilliantly surprised I was! This is not your standard corporate sales-fest; Green IO is the real deal. A conference full of people doing work they care about for the good of the planet – I’ve found my clan and I’ll be back!”
Fiona MacNeill, Director - UX (Research & Strategy, Macknowlogist)
"The blossoming of tools and initiatives in greening IT is a heart-warming signal from the digital sector. More than ever sharing experience and insights is pivotal for actors to ramp-up their effort."
