Extending to present more green credentials

[dotjay]

Good work, Chris! While I totally understand that this is meant for presenting meta data for websites (like robots.txt) that can be crawled, I wonder if there's an opportunity to extend the idea to also present more green credentials for an organisation, such as the providers they choose to use.

For example, to show that the organisation choose a green energy supplier, you might have something like:

[gas]
