Re: Introducing a new HTTP response header for Carbon Emissions calculation

I enthusiastically support this idea. I disagree with the list-of-decimals
proposals - when I invoke a service I want to know how much carbon it cost,
and maybe I want the provider to reduce it; so the list of decimals would
be something that might happen behind the provider's firewall, to help them
understand contributions to the load. Do the simplest thing first.  And if
you did provide such a list, it would be more useful as a set of name/value
pairs, and then you'd have to agree on the available names and extension
mechanisms, and at least two years would have gone by. This could be
shipped in months and would be a big step forward.

Since Scope-2 talks about CO2-equivalent emissions, and the name as
proposed is REALLY LONG, maybe instead "Scope2-CO2"?
