Very interesting -thanks Hesham.

This is a new SCION paper which uses SCION path aware architecture to estimate and disseminate carbon intensity of inter-domain paths.  You can access the paper here: https://scholar.google.com/scholar_url?url=https://netsec.ethz.ch/publications/papers/green_routing2023.pdf&hl=en&sa=X&d=2221193519881579352&ei=L39TZNbNL4HBsQKHg4Mw&scisig=AGlGAw8bvu6JoiUYgq86kLYpZ0W1&oi=scholaralrt&hist=LiEm55wAAAAJ:6297799576989356312:AGlGAw-I9fbYdpGr-eDV-oh3lITV&html=&pos=2&folt=rel&fols=" rel="nofollow">https://scholar.google.com/scholar_url?url=https://netsec.ethz.ch/publications/papers/green_routing2023.pdf&hl=en&sa=X&d=2221193519881579352&ei=L39TZNbNL4HBsQKHg4Mw&scisig=AGlGAw8bvu6JoiUYgq86kLYpZ0W1&oi=scholaralrt&hist=LiEm55wAAAAJ:6297799576989356312:AGlGAw-I9fbYdpGr-eDV-oh3lITV&html=&pos=2&folt=rel&fols=

SCION team designed CIRo, a system for forecasting the carbon intensity of inter-domain paths and disseminating them across the Internet. Using SCION code base the team implemented CIRo PoC to demonstrate the potential of CIRo for reducing the carbon footprint of endpoints and end domains through large-scale simulations. CIRo PoC  shows that it can "reduce the carbon intensity of communications by at least 47% for half of the domain pairs and the carbon footprint of Internet usage by at least 50% for
87% of end domain."
