Emissions Boundaries & Scope For SCI Equation #87

Ben Davy showed a compelling visualization for his formula that outlines scope. I'm borrowing from his blog post to propose that we do something similar in our SCI for clarity:

Here are the definitions of Scope 1, 2, and 3 according to the GHG Protocol: Scope 1 emissions are direct emissions from owned or controlled sources. Scope 2 emissions are indirect emissions from the generation of purchased energy. Scope 3 emissions are all indirect emissions (not included in scope 2) that occur in the value chain of the reporting company, including both upstream and downstream emissions.

Will need to account for who is reporting this. e.g. who is reporting “If outsourced to the cloud, IT emissions previously accounted for under the Greenhouse Gas Protocol Scope 1 — emissions that are directly linked to the activities of an organization from sources that it owns and control — and Scope 2 — emissions from the generation of purchased energy — move to Scope 3, referring to all other emissions.”
