Summary of S4-260090: Greening of Streaming Collaboration and Media Energy Workshop
1. Introduction and Background
This contribution documents the outreach and collaboration established between 3GPP SA4 and the Greening of Streaming (GoS) organization regarding energy efficiency in media streaming. The source contacted GoS to create awareness of the ongoing "energy for media" work in 3GPP, particularly in the context of 6G where sustainability is a core KPI.
A call was held on December 9 between the source, the study rapporteur, and Benjamin Schwarz (GoS President) to exchange information about respective activities.
2. Greening of Streaming Organization Overview
Mission and Structure
- GoS is a global, member-driven organization focused on making streaming more sustainable and energy efficient
- Emphasizes transparency and evidence-based practices backed by verifiable data
- Operates through multiple working groups:
- Language Lab: Terminology and research papers
- Marketing Lab: Industry presence and education
- Policy & Guidelines Lab: Energy efficiency guidelines
- Watt Lab: Engineering projects including real-time energy measurement
Key Projects (2025)
REM (Remote Energy Measurement Platform)
- Measures actual (not estimated) energy consumption across streaming devices
- Provides data from encoders to home devices
- Key findings include:
- Home gateways use ~10W
- P2P delivery adds minimal overhead
- TV upscaling from HD to 4K can use up to 4W extra
- Network equipment baseline power measurements
EYANG (Energy YANG Data Model)
- Standardized protocol for real-time, component-level energy measurement
- Enables accurate empirical data collection for optimization and compliance
Industry Impact
- White papers on power factor and user-level energy reduction
- Leading measurement efforts for Media Climate Accord (40% emissions reduction by 2030, net zero by 2040)
3. Complementarity Between GoS and 3GPP Work
The discussion identified that:
- GoS focuses on streaming applications
- 3GPP focuses on telco aspects not covered by GoS
- Overlap exists in CDN and streaming delivery areas
- Work is complementary rather than duplicative
Key 3GPP Focus Areas Identified
- Exploring which energy-related data could be meaningfully exposed to users
- Operators seeking regulatory clarity on energy attribution
- Using energy and QoE data for network optimization (OpEx and CO₂ savings)
- 6G emphasis on sustainability and operational efficiency
- 3GPP's role: build the framework for energy-based decision-making (not prescribe specific policies)
4. Leadership Support
Quick consultation with SA4 and MBS leadership confirmed support:
- MBS chair endorsed the workshop concept
- SA4 chair agreed, noting no need to escalate to SA plenary
- MBS chair indicated GoS may become a formal liaison to 3GPP
- 5G-MAG offered to organize the event
