Erica Pisani, host of the Performance and Sustainability track at QCon London 2025, reflects on lessons from assembling the track and from attending the talks. She touches on the importance of the environmental and social aspects of software and hints at how developers can improve them through small steps in the architecture and practices of software development.

How is sustainability covered in main tech conferences? Sure cybersecurity, DevOps, or anything related to SRE, is covered at length. Not to mention AI… But what room is left for the environmental impact of our job ? And what are the main trends which are filtered out from specialized conferences in Green IT such as Green IO, GreenTech Forum or eco-compute to generic Tech conferences? To talk about it Gaël Duez sat down in this latest Green IO episode with Erica Pisani who was the MC of the Performance and Sustainability track at QCon London this year. Together they discussed: - The inspiring speakers in the track - Why Qcon didn’t become AIcon - How to get C-level buy-in by highlighting the new environmental risk - The limit to efficiency: fine balancing between hardware stress and usage optimization - Why performance and sustainability are tight in technology - Why assessing Edge computing’s positive and negative impact is tricky And much more! ❤️ Subscribe, follow, like, ... stay connected the way you want to never miss an episode, twice a month, on Tuesday!
