📈 44 cm water level rise under the IPCC business as usual scenario. This number shows that climate change is very real for Singaporeans and for their data centers, close to 10% of the whole of APAC! 🎧In episode 36, Gaël Duez discussed with Professor PS Lee, National University of Singapore Dean's Chair of Mechanical Engineering and one of the top experts worldwide on data center cooling, the challenges in making data centers sustainable. 🔍Some key points of their exchange are: 🌡️ why temperature rise has multiple downside, ⚡ energy challenges that affects the sustainability of data centers, ❄️ liquid cooling technology as an important option, 🗺️ why lessons from DC operating in tropical climate apply almost everywhere. And much more!

⚙️Cybersecurity and sustainability do share a complex relationship! The two approaches share commonalities, such as grappling with resistance from teams and executives and prioritizing resilience, but they also seem to split in notable ways such as constant updates in cybersecurity impacting bloatware and equipment obsolences. 🎧In this episode Gaël Duez invited two experts on the field, Mary Prokhorova from InDevLab and Michael Oghia from Datacenter Changemakers, to discuss the nuances of cybersecurity and sustainability’s relationship. 🔎Some few takeaways from their conversation are: 💡the critical role of IT infrastructure in modern business processes 💡importance of protecting critical infrastructure to avoid environmental damage and societal impacts 💡significance of investing in digital infrastructure to support the green revolution and highlighting the impact of climate risks on both physical and digital security

🎙️In our latest episode, Hannah Smith, the COO of the Green Web Foundation, and Ismael Velasco, the founder of the Adora Foundation, highlight the potential pitfalls of Carbon Aware Computing a strategy that aims to reduce carbon emissions by aligning software operations with the carbon intensity of the energy grid. While this approach has gained traction among the IT industry, including giants such as Apple, Microsoft, and Google, Hannah and Ismael discuss with our host Gaël Duez its complexities and limitations. 💻As they explored the nuances of Carbon Aware Computing, it gave us insights that while it holds promise as a tool for reducing emissions, it also poses challenges that must be carefully considered. The oversimplification of energy grid dynamics and the myriad factors that influence carbon intensity underscore the need for a more comprehensive understanding of sustainable computing practices.

🔍How open source software slashes energy consumption, extends hardware lifespan, and drives sustainability? 🎙️In this episode, Gael Duez as he unravel the intricate relationship between open source software and IT sustainability together with Oliver Cronk, the host of Architect Tomorrow podcast and Sustainable Technology practice lead at Scott Logic (UK), alongside his software engineer colleague Katie Davis. 💡Open source software (OSS) and hardware (OSH) are not just benefiting companies, but also driving global sustainability efforts. With insights from a recent HBR study revealing OSS's monumental impact on reducing software development costs, the stage is set for an insighful conversation. 💻Katie breaks down the key to OSS success: transparency. Learn how freely available code empowers developers to make efficient, sustainable choices, while Oliver highlights the importance of common hardware standards and circularity to combat waste and inefficiency. 📊Dive into the battle for open-source data transparency with Katie, and explore Oliver's vision for the tech community's future direction. From reducing emissions with initiatives like the Tech Carbon Standard to innovative projects like the Cloud Carbon Footprint tool and the Open Compute Project, the episode is packed with actionable insights and inspiring solutions.

How can we make systemic design operational for sustainable design? 🔧Systemic design is dedicated to handling complex systems, complex questions, and complex issues. Sounds familiar with Sustainability? But if things are so complex how digital product people willing to design sustainably can embrace them? In this episode, we dive deep into the world of systemic design and how it can help us increase digital sustainability. Don't miss out on insights from Sylvie Daumal (acclaimed author of 'Design d'expérience utilisateur' ) and Thorsten Jonas (founder of the SUX Network), as Gaël Duez discusses the operationality of systemic design in Tech.

How do we tackle the Green IT blind spot? 🏞️ In many big corporations, IT is never number one, number two, even number three for GHG emission sources (and other environmental factors). But everyone working in the digital sustainability sector knows that, actually, little streams make big rivers with the digital sector accouting for around 4% of global emissions. 📏 In this episode we explore a very concrete case of measuring IT footprint in a massive corporation: ABB Motion with Thomas Mosser (ABB) and Fiona Leibundgut (SparkIT Consulting). How to kick start, how to leverage the Resilio tool which they chose, how to scale, etc. And the insights shared can be used in smaller organisations as well!

0.9g of CO2e. It’s pretty ridiculous when you think about it. According, the French SRI association this is the carbon footprint for a 10K prints digital campaign with a 200k image. So not a big deal? Not that simple because we’re talking about volumes in trillions per day here. So maybe it’s a good idea to dive a little deeper on the environmental impact of digital marketing after all. Hence we brought 2 experts in AdTech with a soft spot for Sustainability: Diarmuid Gill is Criteo’s CTO since 2019 and has been in Digital Advertising for more than 15 years. Audrey Danthony has also a long career in AdTech, she started her first company, Oxeva, during the dot-com boom when she was still a student at engineering school. And 2 years ago she pivoted and founded with 2 partners Impact+ with the aim of reducing Greenhouse Gas emissions in digital advertising. ❤️ Subscribe, follow, like, ... stay connected the way you want to never miss an episode! 📧 Once a month, we deliver carefully curated news on digital sustainability packed with exclusive Green IO contents in your mailbox, subscribe to the Green IO newsletter here.

What if you could get sued if your website is not low-carbon enough? What if you would be barred from many call for tenders if your digital services don’t hit minimum sustainability requirements? Science-fiction? This is what people said on 5 May 1999 when the first version ever of the Web Content Accessibility Guidelines was released by the World Wide Web Consortium (W3C). 20 years later, these pitfalls are day-to-day concerns for many digital companies and digital service providers.
