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!In collaboration with

09:00 to 09:30Welcome Breakfast — Partners Village
09:30 to 09:5509:55 to 10:3010:30 to 10:55TalkSee 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.11:00 to 11:30Coffee Break & Networking — Partners Village
11:30 to 12:10Panel 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.12:10 to 12:35TalkSee 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.12:35 to 13:00TalkSee 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.13:00 to 14:00Lunch Break & Networking — Partners Village
14:00 to 14:25TalkSee 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.14:25 to 14:50TalkSee moreSustainable AI Agents at Lloyds
Leveraging the hybrid approach of small language model and large language model on top of applying classic energy saving principles and deploying AI agents at scale in production15:30 to 16:00Coffee Break & Networking — Partners Village
16:00 to 16:25TalkMaking Carbon Claims Credible: How ISO 14064 Third-Party Verification Combats Greenwashing
With ECGT enforcement from September 2026, CSRD reporting in full effect, and B Corp v7 mandating verification, self-declared carbon claims are now a legal and reputational risk. Drawing on 20+ years in sustainability standards and original MRes research into ISO 14064 verification, Melanie Blackmore (CEO, Carbonology) gives ESG leaders a practical, non-technical framework for spotting greenwashing and building defensible claims. Attendees leave with a five-point credibility checklist and three concrete next steps.16:25 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.

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."
