The fetcher behind the Green Web Foundation's Green Web Checker. When somebody runs a green check against a domain, the service tries to match that domain to a known green hosting provider by green IP range, by ASN, or by finding a carbon.txt file served over HTTP — and this user agent is used for that last request only. The operator states it will only ever request /carbon.txt and /.well-known/carbon.txt, with a HEAD or GET, and will not touch any other part of a site.
