Two points:

1. It might be worth an effort to see if there are existing knobs to tweak for sustainability. For example, every recommended repetition rate for discovery or refresh messages, especially multicast, could be reviewed to see if it can usefully be slowed down. Every link-local protocol could be reviewed for compatibility with wake-on-LAN.

2. Network Energy Management could be a good topic for an IAB workshop or program.

Not a joke: before investing much effort in this topic, we should consider whether that effort (e.g. convening a workshop) will consume more energy than it saves.
