🎤 Talk 1: Sustainable Technology & the "3 Cs" 🌱

Speaker: Subramanian Kuppuswami
Title: Global Sustainability Head, BFSI; Top 25 Sustainability Leaders 2024 👏

Summary:
Subramanian's talk centered on the "3 Cs" of Cost, Carbon, and Cloud as pillars of sustainability in technology 🌍, highlighting both the opportunities and challenges posed by advancements in AI 🤖, Cloud ☁️, and Future Computing (such as Edge and Quantum computing). He shared an insightful analogy comparing the resource-conscious nature of film photography 📸 to today’s digital habits—where the ease of clicking countless photos masks the CO₂ footprint generated 🌿. This shift underscores the importance of awareness and sustainable design principles in technology.

The ICT industry accounts for 2.1–3.9% of global greenhouse emissions 🌎, with software's current carbon contribution lower than other sectors. However, this figure is anticipated to grow sharply due to AI, GenAI, and ongoing digital transformation. Subbi emphasized that organizations are now expanding their sustainability initiatives to address software’s energy impact at every lifecycle stage—from development through to operations 🔋. However, they face challenges due to a lack of detailed and transparent energy and carbon data 🔍.

Conclusion:
Subbi posed a critical question: "Will moving to the cloud alone solve these challenges?" 🌩️ He urged for architectural solutions and innovations to engineer a sustainable future by tackling the deeper issues of energy efficiency, data transparency, and sustainable software practices 🔧💡.

🎤 Talk 2: Transforming Data Centers with eBPF ⚙️

Speaker: Daniel Finneran
Title: Principal Community Advocate at Isovalent 🖥️

Summary:
Daniel discussed the evolution of IT infrastructure and the industry's reliance on power-hungry devices within data centers worldwide 🌐. Over the past decade, data centers have made strides in energy efficiency ⚡ by consolidating workloads using virtualization, containerization, and Kubernetes 🚢. Now, the rise of eBPF (Extended Berkeley Packet Filter) is further transforming data center efficiency by reducing reliance on additional hardware devices 🔋. Dan explained how eBPF works and its applications in networking, observability, and security 🔍, highlighting that offloading processing to eBPF programs could significantly reduce the data center footprint 🌱.

He emphasized eBPF's potential to replace traditional hardware like load balancers, firewalls, TAP devices, and IDS (Intrusion Detection Systems) 🔒. As an open-source technology, eBPF allows for customization, meaning developers no longer have to wait for vendors to deliver solutions but can instead tailor tools to their own specifications. Dan also referenced KEPLER (Kubernetes-based Efficient Power Level Exporter), a cloud-native project leveraging eBPF to monitor energy usage within Kubernetes clusters, exemplifying how eBPF can drive energy-conscious computing ⚡🔋.

🎤 Talk 3: Optimizing Compute Density in Cloud ☁️

Speaker: Charles Humble
Title: Freelance Techie, Podcaster 🎙️, Editor, Author 📚, and Consultant at Conissaaunce Limited

Summary:
Charles emphasized the efficiency of high compute density in managed cloud services 💻, which allows shared resources across vast numbers of users to achieve optimal energy utilization 🔋. However, he noted that while many sustainability guides recommend shifting to the cloud 🌩️, it's crucial to consider green software principles for all environments 🌱. Charles provided practical advice on assessing current system efficiency, optimizing code and language choice 💻, and effectively communicating the value of green practices to leadership 🗣️.

He introduced energy proportionality, a concept from Google showing that even idle servers consume about half their power ⚡. To optimize energy use, Charles advised aiming for at least 50% machine utilization across all systems and eliminating “zombie” servers—unused machines still consuming resources 🧟‍♂️💻. He suggested regular audits and a “LightSwitchOps” approach, shutting off non-essential systems during low-demand hours 🕹️ for companies with localized or non-global operations.

Recommendations:
Charles recommended optimizing workloads based on green energy availability 🌱, mentioning the real-time carbon intensity tool from Electricity Maps, which AWS, Google, and Salesforce use to help customers select eco-friendly energy sources 🌞. He encouraged organizations to publicly share their achievements through case studies, conferences, and articles to foster broader adoption of sustainable practices 📣, concluding with the key message: focus on operational efficiency as a first step in software sustainability, not just on the code itself 👨‍💻.

🎤 Talk 4: Sustainability Measurement Frameworks 📏

Speaker: Dr. Swati Murthy
Title: Practice Director - Sustainability | Tata Consultancy Services | IRCA Certified ISO 50001 Auditor and Lead Energy Assessor 🌱

Summary:
Dr. Swati discussed the current limitations in sustainability measurement frameworks 📊, which often focus on enterprise-level ESG (Environment, Social, and Governance) goals 🌍 without industry-wide standards for impactful, cross-ecosystem sustainability outcomes 🌱. She introduced a proposal to embed sustainability throughout the design process by defining foundational elements, core principles, and key business imperatives for creating sustainable solutions.

A significant focus was on supply chain decarbonization as the "missing link" 🧩 in achieving net-zero targets ♻️, emphasizing the need to integrate sustainability from the ground up in supply chain management to drive meaningful environmental impact across industries 🌐🌍.
