If you prefer listening, check out our podcast summarizing the most relevant insights from Sustainability & Green ICT CW 08/ 09:

AI & Energy

  • Discussion moved from per query metrics to supplier level transparency on energy, emissions and water use, with calls for comparable disclosure

  • Voices highlighted stress on power and water systems from fast growing data centers, urging local planning that recognizes physical resource limits

  • Scaling AI in regions such as Southeast Asia was framed as a trade off between optimization benefits and higher emissions from dense infrastructure clusters

  • Hardware, GPUs and image generation were described as concrete drivers of electricity demand, reinforcing the need for sustainable GPU clouds by design

Green Software

  • Green coding was presented as a strategic discipline that improves performance, data integrity and energy efficiency rather than a niche side topic

  • Contributors argued for simpler, more efficient architectures instead of complex, wasteful stacks that consume unnecessary compute and storage

  • Agentic coding and local AI approaches were positioned as ways to cut data transfers and reduce external model calls during development and operations

  • Multi week lecture series and publications showed green software building a structured knowledge base, supported by emerging standards for resource efficient code

Governance & ESG

  • ESG training for boards and senior leaders underscored that sustainability literacy is now a baseline requirement for credible transformation programmed

  • Examples from organizations integrating climate targets into incentives and scorecards showed sustainability moving into core governance, not only external reporting

  • Commentary stressed that sustainable IT needs clear responsibilities, procurement criteria and risk frameworks, connecting green coding and Responsible AI into one model

  • Regulatory moves such as infrastructure acts, trade measures and net zero litigation were framed as mechanisms that tighten accountability for digital emissions

Climate Tech & Energy

  • Climate tech founders and investors emphasized operational discipline and solid unit economics, with capital flowing to solutions that scale impact quickly

  • Corporate milestones in renewable sourcing, including full coverage through long term power contracts, illustrated how large buyers can unlock clean energy projects

  • Verified soil carbon credits and nature-based removals were highlighted as evidence that high quality carbon markets and monitoring are gaining traction

  • Debates on political choices that favour fossil power for AI stressed the risk of lock in and the need to keep the transition both affordable and forward moving

Circular IT

  • Circular IT content focused on structured asset disposition and lifecycle services that prioritize refurbishment, redeployment and recycling over linear replacement

  • Collaboration examples with utilities illustrated how coordinated programmes can extend equipment life and increase material recovery from digital infrastructure

  • Whitepaper led discussions examined responsibilities across the digital market, linking circular design, product stewardship and allocation of environmental burdens

  • Events and forums that combined circular economy, nature restoration and digitalization signaled a more systemic view of material flows and ICT planning

Ecosystem & Products

  • New offerings such as greener AI services, renewable powered models and privacy focused eco chatbots showed a growing product layer around sustainable digital services

  • Data centre expansions with high renewable shares, certifications and efficient cooling illustrated how infrastructure providers position themselves as green cloud leaders

  • Summits and awards on digital sustainability provided platforms to share best practices on inclusion, resource recovery and climate aligned innovation

  • Webinars, podcasts and curated news formats on AI emissions, sustainable browsers and big tech climate moves helped practitioners track developments efficiently

Everyday Practice

  • Stories promoted small, practical steps to cut digital footprints across devices and services, arguing that consistent incremental actions can compound into real impact

  • Reflections on technology’s environmental effects framed sustainable IT as part of professional identity and daily decision making for technologists and managers

  • Voices highlighted the contribution of women in IT, linking diversity to better decisions on environmental and social dimensions of technology

  • Contributors stressed that real progress often looks like steady, unglamorous work, with certifications and continuous improvement cultures outweighing headline announcements
