Day 1: Workshop Day [Room: GALERIJ]
Tuesday 9th June 2026
09:30 to 09:55WorkshopSee moreThe Cascading Cognitive Calamity of the Carbon Cargo Cult
Most digital sustainability work still optimises solely for carbon. This session unpacks why that misdirects decisions, compromises ESG reporting, and compounds the problems of mitigation‑only thinking, while also ignoring the most pressing issues of the AI boom such as local water stress, grid constraints, and social licence to operate. We will then cover why the ground breaking new Commons Atelier/GeSI data centre blueprint uses a multi‑capital, net‑impact approach that respects real‑world constraints beyond carbon to advance digital sustainability.

Day 2: Conference Day [Room: GALERIJ]
Wednesday 10th June 2026
09:30 to 09:55OPENING REMARKSSee moreLearning How to Scale from Dutch Resistance During WWII
09:55 to 10:20KeynoteSee moreThe Digital Future Is Degrowth
An inconvenient truth is that the things we do, the actions we take, are not enough: sustainability in our digital world is not spreading fast enough. We need more. Or less. Here's how to apply agile principle number 10 - maximising the amount of work not done - to everything you do - or decide not to do - in our digital realm. Let's rethink our endless growth paradigm and walk away with a renewed love for the YAGNI-principe (you ain' t gonna need it!) And with practical inspiration from Stoic philosophy that less is more. Presentation slides10:20 to 10:45Coffee Break & Networking
10:45 to 11:10TalkSee moreEmbedding GreenOps in Practice: From Framework to Organizational Impact
How can organizations embed GreenOps in a practical, scalable, and organization-wide way? On behalf of the National Coalition for Sustainable Digitalization (NCDD), we present the GreenOps Framework, complemented by insights from the Sustainable IT Impact Assessment (SIIA). Together, they offer a practical, end-to-end framework that helps organizations understand, prioritize, and act on the environmental footprint of their IT. After briefly touching on the underlying principles, the focus shifts to real-world case examples that show how organizations are turning sustainable IT ambition into day-to-day practice. Through concrete experiences and lessons learned, this talk aims to inspire participants on how GreenOps can be embedded across teams, processes, and decision-making to drive meaningful and lasting impact. Presentation slides11:10 to 11:35TalkSee moreCustomer Success with GreenOps for Cloud and AI - Double Wins for Cost Savings and IT Sustainability. Customer Showcase.
Real-world customer success stories that drive the double wins of cost reduction and hitting IT Sustainability goals. Data-driven execution of GreenOps and FinOps. Practical use cases you can use. Includes Sustainable AI - the fastest growing segment of both cost and emissions. Greenpixie provides the data and tools needed to evaluate 220 LLMs for proactive selection of model, the way it is used, and where it is run. Shift Left and Sustainability by Design. Customer showcase updates, including Mastercard, ABB and NTT Data. Presentation slides11:35 to 12:00TalkSee moreKEIT, One Year On: Measuring Kubernetes Carbon on a Sovereign Cloud
A year and a half ago at Cloud Native Sustainability Week here in Amsterdam, we introduced KEIT, an open-source tool for measuring Kubernetes emissions. A lot has changed since: cloud sovereignty has taken on real urgency, European clouds have shipped native carbon APIs, and Kepler, the energy tool we'd relied on, works best on bare metal, which not every cluster offers. Presentation slides12:00 to 12:25TalkSee moreGreen Coding with GitHub Actions
Sustainability in software requires moving beyond intent to automation. In this session, Max and Wilco will demonstrate how to automate green software implementation using GitHub Actions, focusing on two primary models: rules-based automation and agentic performance engineering. They will provide an overview of the tooling, share live examples, and walk through real-world case studies. You will leave with immediately actionable approaches and a practical framework for reducing the environmental footprint of your software through intelligent automation. Presentation slides12:25 to 13:40Lunch Break & Networking
13:40 to 14:05TalkSee moreProcurement as the lever to create a market for Sustainable IT
Procurement as a lever to create a market for Sustainable IT How: enable software vendors and service providers to differentiate with resource-efficient products as well as advice. Case Study: City of Amsterdam, how they are enabling the market by asking for reporting & improvement plans, creating an incentive for suppliers to do better. If vendors have an incentive to report and improve, it: a) creates demand for knowledge on how to lower their footprint b) creates demand for measurement tooling and automation, and c) enables software engineers interested in reducing the impact of their work to get more time to learn & engage with the topic, as it will start increasing the chances for their company to win tenders. Presentation slides14:05 to 14:30TalkSee moreWhy Measuring Digital Carbon Is Hard (and What SCI Actually Looks Like in Practice)
How do you measure the carbon footprint of a digital service in real life? This talk presents a Finnish healthcare case where the Software Carbon Intensity (SCI) standard was used within a broader Caring Nature-aligned assessment of remote and in-person care. We measured backend infrastructure, data transfer and user devices using cloud data, telemetry and modelling. The result was not a textbook SCI exercise, but a practical IT project: data, ownership, architecture, documentation and collaboration mattered as much as the formula. Presentation slides14:30 to 14:55TalkSee moreEmbedding ICT Sustainability: A European IT Organization’s Concrete Journey and Key Learnings
I am delighted to be speaking next week at Green IO Amsterdam 2026, joining an international community of practitioners committed to advancing sustainable IT. In this session, I will simply share my experience from within a large European public organization—focusing on how ICT sustainability initiatives were concretely implemented, what delivered real impact, what proved more challenging, and how we can collectively keep driving progress on this critical topic. Above all, this is an opportunity to exchange insights and learn from one another as peers. Presentation slides14:55 to 15:20TalkSee moreThe Human Side of Sustainable IT
Sustainable IT is often framed as a regulatory or technical challenge, which can feel overwhelming to tackle as an individual contributor. In this talk, Corina and Chris will explore digital sustainability through the lens of people, processes and technology, focusing on the opportunities for impact in our daily (work) life. From personal choices to architectural decisions, this session highlights where individuals can influence change, inside or outside formal sustainability roles. It also explores how communities can act as a catalyst for change, showing how shared learning and connecting with like-minded peers can turn green IT from an abstract concept into tangible action. Sustainable IT is a journey that does not start with perfect solutions, rather with awareness and intentional actions, enabled also through communities. One Byte at a time.

15:45 to 16:10TalkSee moreFrom Hundreds of VMs to One Laptop
Have We Lost the Art of Using a Computer? Cloud abstracts the bill. Frameworks abstract the work. Somewhere in between, we forgot how computers actually work - and we're paying for it twice, on the invoice and on the grid. A real workload. A real rebuild. A 90% infrastructure cut. This is a talk about writing the kind of code we'd convinced ourselves wasn't worth the effort anymore. Presentation slides16:10 to 16:35TalkSee moreMatch Made in Heaven: Accessibility and Green Software
Being kind to the environment and being kind to people usually go hand in hand in real life. And this is also the case for your User interfases. In this talk we will dive deeper into what best practices work best to develop an frontend application that is both accessible and green. But also in what sense they might fight eachother al little. You will walk away from this talk with deeper understanding and an actionable way of work to create your next application fully accessible and very green! Presentation slides16:35 to 17:00TalkSee moreGenerating Energy-Efficient Code via Large-Language Models--Where are we now?
The rise of Large Language Models (LLMs) has led to their widespread adoption in development pipelines. We empirically assess the energy efficiency of Python code generated by LLMs against human-written code and code developed by a Green software expert. We test 363 solutions to 9 coding problems from the EvoEval benchmark using 6 widespread LLMs with 4 prompting techniques and comparing them to human-developed solutions. Energy consumption is measured on three different hardware platforms: a server, a PC, and a Raspberry Pi for a total of ~881h (36.7 days). Human solutions are 16% more energy-efficient on the server and 3% on the Raspberry Pi, while LLMs outperform human developers by 25% on the PC. Prompting does not consistently lead to energy savings, where the most energy-efficient prompts vary by hardware platform. The code developed by a Green software expert is consistently more energy-efficient by at least 17% to 30% against all LLMs on all hardware platforms. Even though LLMs exhibit relatively good code generation capabilities, no LLM-generated code was more energy-efficient than that of an experienced Green software developer, suggesting that as of today there is still a great need of human expertise for developing energy-efficient Python code. Presentation slides17:00 to 17:25TalkSee moreScaling GenAI Without Burning Cash and Carbon: Rabobank’s Approach
As GenAI adoption accelerates, cost and carbon quickly emerge as important considerations. This talk explores how Rabobank scales GenAI while keeping financial discipline and environmental impact front and center. Expect practical lessons on how FinOps and sustainability work together to enable GenAI adoption at enterprise scale. Presentation slides

Why they attended our past Amsterdam editions
The Green IO Conference is more essential than ever, especially with the rise of AI, whose environmental impact must also be measured and optimized within our organizations. But that is not all—the timing is critical. When sustainability comes rushing back to the forefront, faster than you might expect the teams that have already embedded it will be ready. And you will know that you persevered and made the right choices. While visiting the remarkable, small, and recently opened Fernand Léger Museum in Argentan, I came across one of his quotes that struck me. Léger, a master of contrast and modernity, inspired me to adapt his words by replacing “painter” with “IT professional.” It becomes: “As an IT professional, I believe in the significant role of my peers in the evolution of society.” Every IT professional carries responsibility for shaping society and for the environmental footprint of the digital sector. On one hand, we must understand, control, and reduce the environmental impact of digital transformation in organizations. On the other, we must also assess and measure its benefits.
