In this blog post, I'd like to highlight what MPEG can do to protect the planet (with standards). In general, each generation of video codec improves coding efficiency significantly (by approx. 50%) but with increased complexity that impacts compute/memory requirements. An overview of the video codecs can be found in the figure below and I would like specifically point to MPEG-2 (H.262 | 13818-2), AVC, HEVC, and VVC.

The performance history of standard generations can be seen in the figure below which roughly indicates the 50% bitrate reduction at a given constant quality.

Furthermore, MPEG specified ISO/IEC 23001-11:2019 also referred to as "Energy-efficient media consumption (green metadata)" that specifies metadata for energy-efficient decoding, encoding, presentation, and selection of media. The actual specification can be purchased here and an overview can be found also here.
ATHENA and APOLLO projects). In this context, we are organizing a special session at PCS'21 entitled "Video encoding for large scale HAS deployments" where we argue that optimizing video encoding for large scale HAS deployments is the next step in order to improve the Quality of Experience (QoE) while optimizing costs.
Since July 2020, MPEG is operating under a new structure and while writing this blog post, the 132nd MPEG meeting is taking place online discussing new standards according to its roadmap (see figure below). An overview/archive of my MPEG reports can be found here and the report for the 132nd MPEG meeting will be there also shortly after the MPEG meeting.
