  • Green IO is THE podcast for anyone interested in ICT sustainability

    The title says it all – Gaël is an excellent host, it is well-researched, always inclusive of great/knowledgable guests, and the production quality is so good! It’s also impressive to see such a useful podcast from an individual creator (and not a major media company). Keep up the great work!

Talking Points

Recent interactions between the hosts and their guests.

The dilemma of using AI for sustainable software engineers, with Natasha Ann Lum | #77| 77
Q: What practical approaches can engineers use to mitigate environmental impact while still benefiting from AI?
Engineers should favor mechanical automation over agentic, energy-intensive autonomy when possible, diversify tool usage to avoid lock-in, implement robust CI/CD and automated testing, push for local compute when feasible, and adopt a skeptical, constructive stance when adopting AI tools to ensure best practices and governance are maintained.
Shifting Social Norms in Sustainability Leadership, with Andrea Learned | #76
Q: How do you balance urgency with positive framing in sustainability work?
By connecting human values to daily professional actions and showing tangible, small steps that lead to bigger changes over time, focusing on social proof and joyful leadership rather than doom and gloom.
Streaming, Networks and Sustainability, with Dom Robinson | #74
Q: Does it make sense to measure carbon per gigabyte?
Measuring carbon per gigabyte is flawed as it often overlooks the broader implications of network energy consumption in relation to real-world usage.
Streaming, Networks and Sustainability, with Dom Robinson | #74
Q: Is it feasible to scale up or down a network architecture to save on energy consumption?
Scaling a network for energy savings is complex; the real energy consumption is in the baseline of the network's availability, rather than its usage cycle.
#73 Gerry McGovern vs the Growth Death Cult
Q: Could you tell us more about it and why you started an entire book about the environmental footprint of the tech industry by The Confession?
Gerry reflects on how early experiences with the internet gave him a sense of hope, which later led to disappointment as he saw the negative impacts of technology unfold.
