Carbon.txt

Overview
carbon.txt is a proposed web standard for making it possible to verify that web-infrastructure uses green power, in lieu of green power, users of the standard will simply be able to see what type of power is being used by a hosting provider. The standard is designed to be chained from web-site to host to electricity provider, creating a graph of dependencies. A graph-like approach enables hosting-providers with other upstream hosting dependencies to link to those, and likewise, until an electricity provider is located.

Content may look as follows:


 * 1) we assume most sites have one main provider which might provide the servers
