Greater visibility into CDN emissions

• The group explored how customer‑facing dashboards can provide actionable, usage‑based electricity and emissions data, helping organisations better understand and manage their Scope 3 digital emissions.

Clearer allocation methodologies

• Discussion highlighted the importance of transparent approaches to allocating shared infrastructure emissions, and the value of providing electricity consumption data alongside carbon metrics to support technical optimisation.

Decarbonisation priorities across networks

• Energy efficiency, supplier engagement and renewable electricity procurement were identified as the largest levers for reducing network‑related emissions, with growing expectations from customers helping to accelerate progress.

Beyond carbon alone

• While energy and emissions remain central, participants discussed emerging considerations such as water use, cooling technologies and location‑specific biodiversity impacts of data centres.

Understanding what’s known and what isn’t

• The group reviewed a “known vs. unknown” framework to distinguish established evidence from open research questions across networks, CDNs and data centres, helping to guide future collaboration and research priorities.

Mixed transparency across providers

• A review of third‑party sustainability tools showed uneven levels of disclosure across cloud and CDN providers, with progress in some areas but ongoing gaps around embodied and upstream emissions.

Collaboration as a critical enabler

• The session reinforced that meaningful decarbonisation depends on close cooperation between infrastructure providers and their customers, with feedback loops helping shape better tools, data and decisions over time.

The session strengthened shared understanding of how network infrastructure contributes to digital emissions and set a clear direction for further collaboration, evidence‑building and engagement across the value chain.
