Day 2 - Conference Day
Wednesday 16th April 2025
09:45 to 10:0010:00 to 10:50KeynoteSee moreAI’s energy dilemma: empowering developers for a sustainable future
As AI reshapes the technology landscape, its environmental cost cannot be ignored. With compute demands growing 4-5x annually, AI’s carbon footprint is poised to double data center emissions by 2030. In this keynote, we’ll explore the dual role of AI as a challenge and opportunity for sustainability. Discover how industry innovations—from energy-efficient hardware to software optimizations—are reducing AI’s energy footprint. More importantly, learn how developers can design smarter, simpler systems, integrate energy observability into their pipelines and turn AI into a force for sustainability without compromising progress. Presentation slides10:50 to 11:10Coffee Break & Networking
11:10 to 11:35TalkSee moreNavigating the twin transformations: AI and sustainability – from large models to green practices
The world stands at the cusp of two transformative shifts: the AI revolution and the energy transition. Dr. Lawrence Wee, Director, Business & Ecosystems, IMDA, will explore their intertwined nature, emphasising the need for a sustainable approach to AI development. He will address the growing energy demands of AI, and discuss strategies for mitigating their environmental impact through techniques like model slimming and optimisation. Dr. Wee will share Singapore's multifaceted strategy for greening the digital landscape, including green data centres, green software, and global partnerships. Presentation slides11:35 to 12:00TalkSee moreDatacenter decarbonization through software efficiency
If we can make software energy-aware, we’ll unlock higher levels of datacenter energy efficiency. However, much of today’s software isn’t energy-aware. In the best of circumstances, it is cost-aware – in the worst, not even that. Using cost as a proxy for carbon emissions has its pitfalls. Conversely, making existing software energy-aware has an engineering cost. In this talk, we’ll discuss why energy is a better proxy for carbon emissions. We’ll also discuss two techniques that can help strike a balance between energy awareness and engineering cost – particularly for enterprise applications. Presentation slides12:00 to 12:25TalkSee moreTransformative ESG work in manufacturing
At the GreenIO Conference, I will share how Razer Inc. is driving transformative ESG practices in manufacturing—moving beyond compliance to real impact. As Global Sustainability Lead, I’ve led efforts to integrate sustainable materials, adopt circular economy principles, and achieve net zero goals. We’re advancing ethical supply chains, leveraging technology for ESG tracking, and fostering collaboration through initiatives like #GoGreenWithRazer. These actions reflect our belief that sustainability is not just a responsibility but a strategic advantage—one that drives innovation, accountability, and long-term value across the industry. Presentation slides12:25 to 12:50TalkSee moreAccor case study; a greener IT through migration to the cloud
With sustainability higher on the tech agenda for a few years now, a number of studies have been published over time showing that carbon footprint on the cloud may be significantly better than managing resources on-prem for most companies. At the same time, it is estimated that, globally, the Carbon footprint of Digital and Cloud has surpassed the aviation footprint. So where’s the truth? In 2022 and 2023, Accor achieved a massive cloud migration of 45 regional on-prem datacenters and server rooms across the world. The teams took that opportunity to assess at the same time the Carbon footprint evolution in this before / after cloud migration context. In his talk, Khang will take you through the sustainability learnings of this major migration program, as well as the considerations Accor has been taking towards Green IT as part of its journey to the Cloud.

13:50 to 14:15TalkSee moreImagining a grid-aware web
What if websites could adapt their behaviour based on the electricity powering them? This talk explores the vision of a grid-aware web that responds dynamically to the availability of clean power sources. We'll examine the role that developers, designers, and decision makers can play in pioneering a web that operates with a sustainable focus. Presentation slides14:15 to 14:40TalkSee moreThe quest for the greenest LLM - insights from the frontlines
Generative AI is transforming industries, but its environmental footprint remains largely invisible. In this revealing talk, Jean-Philippe Ehret presents exclusive insights from a comprehensive environmental impact analysis of major LLM models, peer-reviewed by his team. Enterprises and developers will learn: The true environmental impacts beyond energy and carbon Why rare earth minerals are more important than energy consumption The key decision points that will shape the sustainability of your AI strategy As regulatory pressures increase and market expectations evolve, the insights from this pioneering research will help you navigate the complex sustainability decisions that now confront every organization implementing AI at scale. Presentation slides14:40 to 15:05TalkSee moreDesigning for change: how UX can help solve the climate crisis
Tackling climate change isn’t just about awareness—it’s about action. Yet, sustainable choices are often difficult, unclear, or unappealing. User experience (UX) design can change that. This talk introduces UX principles and behavioral nudges, showing how tech and digital tools can drive sustainable behavior at both individual and communal levels. From smart thermostats to choice architecture, we’ll explore how data-driven decisions and intentional design can make green choices the default—shaping a future where sustainability is effortless.

15:30 to 15:55Coffee Break & Networking
15:55 to 16:20TalkSee moreE-waste in Singapore; a dream?
A more crucial point, the environmental impact of technology is also often underestimated because the processes of its production, use, and disposal are largely invisible to consumers. In Singapore alone, we generate 60,000 tonnes of e-waste annually – roughly equivalent to discarding 37.5 million laptops – yet only 6% of this is recycled to recover valuable resources. The discussion will cover Singapore’s e-waste recycling landscape and the solutions KGS offers. It will also highlight case studies demonstrating how the KGS approach has helped stakeholders improve their recycling efforts through sustainable and efficient practices. Presentation slides16:20 to 16:45TalkSee moreClosing the loop: how your IT devices can drive the circular economy
IT devices are ever present in our everyday lives. In this talk, Soo Lin will share about how IT devices can drive the circular economy through reuse, refurbishment, and responsible recycling. Learn more about how HP is leading the way in creating a more circular economy and understand the importance of design in embedding circularity and using sustainable materials. Presentation slides16:45 to 17:10TalkSee more5 lines of code to save the world?
Much of the focus in Green IO is understandably on measuring, reducing, and eliminating the carbon and water footprints of digital technology. Today, especially AI is accused of accelerating climate change. Yet, as renewable energy skyrockets, green digital technology is evolving into something totally different. By 2030, the primary role of green digital technology will be to boost customer loyalty and business growth through the restoration of nature. Handprint.tech was founded in 2020 with a vision to create the first universal impact API and enable this. Let’s peek under the hood together. Presentation slides17:10 to 17:35TalkSee moreTipping the scales: democratising measurement
For centuries, those in power have used measurement to their advantage. In the digital age, this imbalance grows as software’s boundaries blur. It’s time to fight back, not with protests, but with data. This talk explores how measurement has been used to seize and reclaim power, leading to today’s sustainability battlefield. The Software Carbon Intensity (SCI) standard helps measure software’s environmental impact. You’ll learn to calculate SCI using the open-source Impact Framework and join a new wave of activists “watchers”, who ensure transparency. Let’s tip the scales back in our favor, one calculation at a time. Presentation slides17:35 to 18:0018:15 to 19:00Afterparty & Networking
