@vladh software engineering research seems to have settled on the terms "sustainable computing" and "green computing" - a search for the former on arxiv.org (https://arxiv.org/search/advanced?advanced=1&terms-0-operator=AND&terms-0-term=sustainable&terms-0-field=title&classification-computer_science=y&classification-physics_archives=all&classification-include_cross_list=include&date-filter_by=all_dates&date-year=&date-from_date=&date-to_date=&date-date_type=submitted_date&abstracts=show&size=50&order=-announced_date_first) turns up quite a few hits. Much of the journal literature is regrettably paywalled (e.g., https://doi.org/10.1016/j.jss.2023.111944), but most authors will share preprints if emailed.
