Greening of Streaming

🎯 Our Policy & Guidelines Lab has published its agenda. The Lab's focus is developing recommendations that reduce energy use in streaming — grounded in measured data, not estimates. To get there, the work is structured across three horizons: short-term best practices (energy transparency, storage, eco-mode standardisation), mid-term device and display questions, and longer-term structural challenges like circularity and consumer awareness. Thanks Barbara Lange, Benjamin Schwarz, Andrew Ladbrook, and Stan Moote for driving this work forward. 👉 Read the full post on our website — link in the comments.

On 19 March, Greening of Streaming will be presenting at a workshop, co-organized with 3GPP and 5G-MAG - The Media Connectivity Association. 👉🏻 If energy measurement in streaming is your thing, this one is worth your time. Benjamin Schwarz will share Greening of Streaming's work and perspective on the topic, and Marisol Palmero will cover the state of energy awareness in today's network management protocols and devices. The agenda also includes presentations from Orange, Ateme, Fraunhofer FOKUS, Qualcomm, Universität Klagenfurt, and 5G-MAG - The Media Connectivity Association, followed by a 30-minute open discussion. 📅 19 March, 15:00–17:00 CET | Online via Zoom Registration is free: https://lnkd.in/e_pJaKnA ---

For too long, energy consumption across the streaming workflow has been estimated rather than directly measured. In this clip, Tania Pouli (Vivid Manta) and Stan Moote (IABM) discuss one of the findings from our Watt Lab hackathon analysis: how resolution and bitrate choices affect energy consumption across encoding and packaging — and why the answer isn't the same for both. 👉 Read the full analysis through the link below. #GreeningOfStreaming #StreamingSustainability #REM

We just published our most rigorous technical analysis to date of real energy consumption across the streaming chain, from encoders to end devices. The November 2025 WattLab hackathon gave us a full dataset with proper statistical depth — thanks to new member Tania Pouli for bringing advanced data analysis to the mix. What the data showed: 📺 Resolution is the dominant driver of encoding power — accounting for around 55% of the variance we observed. Bitrate affects both encoding and packaging, but packaging more consistently. 📱 The biggest playback energy driver isn't stream quality. It's what's on screen. Bright scenes draw more power than dark ones, regardless of how the video was encoded. 🔍 Device type matters more than expected. Power levels vary so widely between displays that comparing them directly doesn't work. All results came from measurement across real devices, with repeatable test sequences. No estimates Thank you to the 13 contributors who made this possible: Alireza Soltaninezhad (TNO), Arian Koster (TNO), Barbara Lange (Kibo121, Inc.), Benjamin Schwarz (Greening of Streaming), Dom Robinson (id3as), Hemini Mehta (PhD) (European Broadcasting Union (EBU)), Kristan Bullett (HNR), Marisol Palmero (Greening of Streaming), Mike Mattera (Akamai Technologies), Simon Jones (Greening of Streaming), Stan Moote (IABM), Tania Pouli (Vivid Manta), and Tim Siglin (Help Me Stream Research Foundation). 👉 Full report in the comments. #GreeningOfStreaming #SustainableStreaming #REM #WattLab #EnergyEfficiency

Our Founder and Language Lab Lead Dom Robinson sat with Gaël DUEZ in a Green IO 🎙️ podcast to challenge one of the industry's most persistent assumptions: that carbon per gigabyte is a meaningful sustainability metric. 👉 Absolutely worth a listen (links in the comments) #GreeningOfStreaming #StreamingSustainability #GreenIO

On the 11 of February our member TNO is hosting a webinar on how streaming impacts our wellbeing, energy use, and the environment. Online streaming has become a part of our daily life, but what does this mean for both us and the planet? If you're curious about the broader impact of streaming and how our behaviour shapes it, this one's worth attending.

Introducing the Greening of Streaming Policy Lab — a working group examining where policy can drive real energy reductions in streaming. The Policy Lab provides a neutral space for analysis grounded in measured data, not estimates. We explore where current policies may unintentionally drive inefficiency and where clearer guidance could unlock energy savings without compromising innovation. Barbara Lange, Policy Lab Chair, kicks off a monthly series exploring the intersection of streaming technology and policy, with the contributions from Andrew Ladbrook, Stan Moote, Marisol Palmero, Agnès Pleinecassagne, and Benjamin Schwarz. 👉 Read the first blog post here: https://lnkd.in/d4Nt-DvK #GreeningOfStreaming #StreamingPolicy #EnergyEfficiency

Greening of Streaming will be at Integrated Systems Europe (ISE) in Barcelona, running February 3-5 at Fira De Barcelona Gran Via. Our president Benjamin Schwarz is already on his way there via the direct Paris-Barcelona train journey organised by ¡AU! — combining networking with lower-carbon travel before the show begins. 🤝 If you're at ISE and want to talk about streaming sustainability, energy measurement, or what we're working on, let's connect. #ISE2026 #SustainableStreaming #GreeningOfStreaming

"What about AI and sustainability?" It's the question our members face constantly from stakeholders. Our Language Lab has just published a position paper addressing exactly that: "Artificial Intelligence in Streaming Media Sustainability: Distinguishing Impact from Innovation." Led by Dom Robinson with contributions from Benjamin Schwarz, Tania Pouli, Walter Bardelle, Marisol Palmero, Arian Koster, and Barbara Lange, this paper examines where machine learning actually appears in streaming workflows and what its energy implications are. The paper confronts the efficiency paradox: AI can simultaneously enable energy savings through optimisation and increase consumption through computational overhead. We focus on AI embedded in streaming workflows—where we have measurement capability and direct influence—while maintaining awareness of the broader landscape. ⚡ Thanks to decodeTV for featuring our work: https://lnkd.in/e-2f2WG4 🔍 Read the full paper on our website: https://lnkd.in/eY6SuN8v #StreamingSustainability #GreeningOfStreaming #AIEnergy

Media Energy Consumption Measurement & Exposure Workshop Co‑organized by 3GPP SA4, Greening of Streaming, and 5G-MAG - The Media Connectivity Association, this workshop focuses on turning energy‑aware streaming from theory into practice—across 5G today and 6G tomorrow. The session connects: ** 3GPP standards work on media energy exposure ** Reference implementations from 5G‑MAG ** End‑to‑end, hands‑on energy measurements across devices, networks, and streaming workflows by GoS Aligned with 3GPP Work Item “Media Energy Consumption Exposure & Evaluation Framework – Phase 2” (WI #1080050), the goal is clear: define what’s technically feasible now, what requires new interfaces or standards support, and how collaborative experimentation can drive deployable solutions. For engineers, architects, and standards contributors, this is about making energy efficiency a measurable, interoperable signal in real media systems—not just an abstract KPI.
