If you prefer listening, check out our podcast summarizing the most relevant insights from Sustainability & Green ICT CW 46/ 47:

‍

AI Efficiency and Green AI

AI’s environmental footprint stayed in focus, with practical steps to minimize carbon and energy use highlighted across workflows
Guidance emphasized efficient design for training and inference, targeting cost and emissions reductions in production settings
FinOps and Green Cloud approaches were presented as twin levers to optimize spend while lowering compute-related emissions
New research examined AI server impacts and proposed sustainable configurations for future scaling
Community sessions reinforced hands-on tactics for greener algorithms and resource scheduling

‍

Data Centers and Energy

Efficiency narratives centered on cooling, server utilization, and power metrics to curb facility-level footprints
Stressed aligning GPU clusters and racks with realistic power envelopes and heat management
Guidance pointed to transparent PUE tracking and operational fine-tuning rather than headline targets
Practitioner tips linked workload placement to local grid conditions and renewable availability
Colocation and hyperscale themes emphasized incremental upgrades over wholesale rebuilds

‍

Renewable Energy and Storage

Integrating solar, wind, and storage into digital operations featured as a practical decarbonization path
Discussions connected workload timing with renewable generation windows to reduce marginal emissions
Battery and grid flexibility topics supported more resilient ICT footprints under variable supply
PPAs and localized sourcing appeared as enablers for stable clean power in compute hubs
Renewables were framed as complementary to efficiency, not a substitute for it

‍

Products and Launches

New tools targeted carbon-aware planning and runtime optimization for AI and cloud workloads
Platform updates focused on greener default settings and easier emissions visibility by service
Offerings emphasized cost reduction and sustainability benefits in the same feature sets
Product narratives favored deployable modules over complex multi-year programs
Rollouts highlighted quick wins such as workload profiling, autoscaling, and idle draw controls

‍

Partnerships and Investments

Collaborations concentrated on uniting carbon accounting, FinOps data, and operational telemetry
Joint efforts aimed to standardize reporting pipelines across suppliers and internal teams
Partnerships supported pilot-to-scale moves for circularity and renewable matching
Investment signals oriented toward measurable abatement in production, not lab prototypes
Alliances linked ICT providers with energy and facilities stakeholders for end-to-end impact

‍

Standards, Policy, and Reporting

Reinforced science-aligned targets, transparency, and consistent disclosure practices
Scope 3 expectations pushed deeper supplier data integration and audit-ready evidence
Guidance favored baselining, assurance, and comparable metrics over narrative claims
Framework adoption aimed to make sustainability data actionable for engineering teams
Reporting discipline was positioned as a lever to prioritize high-return abatement

‍

Circular Economy and E-waste

Circular design and device lifecycle extension emerged as low-risk, near-term abatement options
Refurbish and reuse programs complemented efficiency to cut embodied emissions
Procurement criteria that reward repairability and materials recovery
Pilot results focused on traceability and quality thresholds for second-life hardware
Circular actions were tied to measurable cost savings and resilience in supply

‍

Mobility and EV

Electrified fleets and charging optimization connected directly to enterprise ICT emissions
Smart charging and load balancing were framed as data problems solvable with existing stacks
Telematics and analytics to lower energy cost and improved uptime
Interoperability and reimbursement models featured as enablers of broader adoption
Mobility signals reinforced the role of ICT in real-world decarbonization outcomes

‍

Supply Chain and Procurement

Supplier engagement moved from questionnaires to data sharing and performance incentives
Procurement guidance emphasized carbon-aware SLAs and lifecycle metrics in contracts
Aligning spend governance with verified abatement potential
Category strategies included circularity, energy attributes, and end-of-life planning
