provider to prove that there is a valid signature chain for every meter reading and every carbon intensity figure used in the emissions accounting, but without disclosing the value of those meter readings, the identity of the electricity supplier, or any other internals that might be sensitive. https://doi.org/10.48550/arXiv.2506.16347 http://www.w3.org/2000/01/rdf-schema#comment I believe this approach can be generalised beyond carbon emissions accounting to environmental biodiversity monitoring, where sensor data from protected areas such as Natura 2000 sites must be reported to regulators without revealing exact readings or locations that could endanger species or compromise data sovereignty across national LifeWatch ERIC nodes. https://w3id.org/np/o/ntemplate/CREATOR
