The GHG Protocol sorts emissions into three scopes: direct emissions from sources the organisation owns or controls (Scope 1), indirect emissions from the electricity, heat, steam and cooling it buys (Scope 2), and every other indirect emission along its value chain (Scope 3), the last split into fifteen categories running from purchased goods and services through business travel and commuting to investments. Any disclosure that leans on those scopes and categories should spell out what the scopes mean and say which categories are inside the figures. Annex D adds two points: an annual report that uses scope language should give readers a short explanation of each scope, and where only part of a scope is covered (Scope 3 business travel, say) the report is required to name the underlying categories so that readers know what the number contains.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
