ECOFLOW is one of the world’s stand-out initiatives focused on making TV streaming more sustainable. We hear from key project stakeholders about the effort to benchmark the carbon footprint of streaming, establish standardised methods to measure streaming energy consumption, identify energy saving opportunities and provide actionable blueprints for sustainability. This project tested and compared proposed energy savings features, evaluated their network and device impacts and sought to understand their impact on user behaviour. Changes as diverse as multicasting and P2P streaming, darker coloured UIs, and device defaults to SDR rather than HDR settings were considered, among other things. You will hear key learnings on how to measure streaming energy consumption, and we ask if standardisation of measurement methods is central to industry transparency, fairness and success. Results are reviewed and we explore what happens next.
