Listen to our podcast

AI for sustainability and efficient AI

Prioritize leaner models, energy-aware scheduling, and continuous impact monitoring, treating sustainability as an operational constraint rather than an afterthought
Balance ambitions with sector realities, with healthcare voices urging patient safety to stay paramount while efficiency gains are pursued in parallel
Push for standardized footprint disclosure, building on prompt-level energy and water reporting to enable like-for-like benchmarking and real governance
Translate strategy into tools and actions, with playbooks and green action agents intended to nudge low-impact choices across day-to-day decisions

‍

Data centers, cloud energy, and cooling

Expansion updates underscored sustainability-by-design facilities, including a Swiss operator entering Germany to provide energy-efficient, high-availability capacity for AI growth
Cooling innovation remained central, with zero-water and advanced liquid approaches framed as credible paths to manage thermal loads at AI scale
Location strategy and grid alignment featured repeatedly, linking site selection with renewable access, resilience, and community impact
Buyers were urged to interrogate providers’ energy sourcing, disclosure quality, and operational metrics rather than relying on broad pledges

‍

Green software engineering and IT operations

Green software emerged as a commercial differentiator, tying cost reduction and reliability to competitive advantage in tenders and RFPs
Guidance focused on integrating sustainability into requirements and developer workflows early, not as a later optimization step
Practical levers included workload right-sizing, efficient data pipelines, and observability tied to energy and latency outcomes
Teams emphasized measurable practices that scale across cloud, edge, and on-prem without degrading user experience

‍

Policy, coalitions, and ecosystem

National coalitions for sustainable digitalization called for aligning IT strategy with environmental outcomes and public value
Multi-stakeholder forums translated ambitions into operational blueprints, prioritizing the intersections of emissions, cost, and service quality
Public sector dialogues stressed procurement criteria that reward auditable impact, not marketing claims
Cultural narratives highlighted nature, technology, and creativity as complementary drivers for adoption and legitimacy

‍

Partnerships, pilots, and new products

A partnership between Lektra and EG4 Electronics introduced battery systems integrated with AI micro data centers, signaling convergence of storage and compute at the edge
Conference and community updates showcased collaborative builds around sustainable digitalization, from EMS platforms to digital spines for city-scale services
Executive posts pointed to greener materials and supplier choices, such as low-embodied-carbon inputs, entering mainstream procurement discussion
Product narratives favored deployable building blocks over distant roadmaps, encouraging pilots that validate energy, resilience, and cost outcomes

‍

Measurement, reporting, and transparency

Posts pushed for comparable AI and cloud disclosures that specify system boundaries, methodologies, and underlying assumptions
Lifecycle-based KPIs were encouraged to ensure gains at development, deployment, and operations stages are captured and verified
Credible reporting was framed as both compliance and competitiveness, enabling better vendor selection and internal capital allocation
Leaders highlighted prompt-level and workload-level metrics to move beyond annualized claims and toward operational governance
