There were about a dozen more papers which looked interesting, but I could not locate the full text of, despite having access to the library at a world leading university. There were many other papers where the grammar of the article was so hard to follow it was difficult to work out what the author was trying to say. Then there were the bulk of papers which did not seem to be saying much at all, at least nothing new.
One thing which would help such a search would be the ability to limit it to open access publications. Unfortunately, Google Scholar does not appear to have this option. Adding the phrase "open access" to the search doesn't really help: some papers are open access, but others are about open access and others are from a publisher which mentions other papers are (but no the one cited). A search using a specialized open access search tool "OAIster" resulted in only eighteen papers on ICT sustainability for 2017. Of these eighteen papers there were five of interest, but three had no link to download and two were behind paywalls of for-profit publishers (thus not open access). The publications which appear to be most readily available are Masters theses from European open universities.
