Methodologies for measuring and estimating energy usage and carbon footprint of streaming
Direct Device Measurement Approach
We conducted lab tests to evaluate the impact of various factors on the energy consumption of end devices, including UI settings, display characteristics, streaming format parameters, resolution, bitrate, device settings, and delivery modes. Using the Fraunhofer Green Streaming framework and analytics dashboards, we developed an ECOFLOW test application with Accedo to explore energy-saving potential. This enabled real-time data visualisation and the capture of extensive power-focused data points throughout our tests.

Summary of Features
Given that previous research tends to point towards end-user devices being a hotspot for energy consumption, we have based our testing on existing and new features created specifically for this project.
Saving energy by adjusting streaming playback dynamically without changing the original content, using AI to optimise settings based on various factors.
Allowing users, on recommended/all content, to stream in audio-mode only, stripping back the video feed to reduce energy consumption.
HDR content requires higher brightness, enhanced colour depth and more complex processing. SDR content, with its moderate brightness and simpler processing needs, uses less energy.
Reduces streaming bandwidth, bitrate and limiting resolution to lower values.
Peer-to-peer streaming, using a decentralised approach to stream video, aiming to reduce energy footprint and reliance on CDN servers.
Using darker colours in the UI of an app can have an impact on its energy consumption.
Streaming apps also provide the opportunity to educate audiences, increasing awareness while also boosting engagement.
Supply Chain Estimation Approach
To support the granular measurement approach, and provide some context as to the broader supply chain impacts, an estimation of the energy consumption and carbon footprint of streaming was conducted.
This involved using the DIMPACT reference architecture and methodology, working with UK data from June 2024, and providing an estimate of the associated per-hour impact of streaming.
This was then broadened to include previous published information from the BBC and the Carbon Trust, providing a range of data points across different scenarios.
Communication & Engagement Approach
As part of the design and product development process, the ECOFLOW project team invited external contacts from various organisations to provide feedback on the ECOFLOW demo app. The purpose of this initiative was to gather insights and perspectives from industry experts and stakeholders.
The external contacts included teams from RTL, BBC, EBU members, and ITV. These teams represented a diverse range of roles, including Designers, Product Owners, Engineers, and Business Analysts. The involvement of these individuals ensured a comprehensive and well-rounded feedback process.
From August 12th to 21st, 2024, the external teams participated in discussions and workshops centred around the ECOFLOW demo app. During these sessions, the project team provided an overview of the initiative, highlighting the current challenges and questions faced.
The participants acknowledged the value and significance of the initiative, emphasising that the topic of sustainability in streaming was not one they commonly considered. They appreciated the effort made by the project team to initiate the discussion, even though some features might have limited impact due to varying factors.
Through the discussions and workshops, the ECOFLOW project team gained valuable insights into the challenges and opportunities related to sustainability in the streaming industry. The feedback received helped refine the understanding of the project's objectives and allowed for a more targeted approach in addressing the identified challenges.
