Section titled “Details”| Property | Value |

| scopeNote | Relative to a stated purchase, never absolute. A sector has no tier of its own — only a tier with respect to something someone bought. Distinct from the GHG Protocol’s ‘tier 1 supplier’, which counts contractual relationships between firms rather than rounds of production between sectors; see the scope notes on the scheme. |
