Carbon Efficiency of Semantic Web and Linked Data Queries

Has anybody done work on Carbon Efficiency of Semantic Web and Linked Data
Queries?

The very nature of distributed data sets has to come with a substantial
computational footprint every time a query is issued to a single node or a
cluster of nodes for a federated query. On the other hand decentralization
might actually outperform more centralized services in the future.

I can find a number of papers and articles related to carbon efficiency in
general computing and cloud computing environments and data centers but
nothing specifically related to the improvement of operational efficiency
introduced by Semantic Web and Linked Data infrastructures.

There is CO2GLE which attempts to estimate the CO2 emissions per second
released by web search engines like Google as a reference here:
