Telstra — carbon factors

Reference emission factors relevant to the this firm's sector, curated from authoritative published sources. Use these to estimate spend-based or activity-based emissions where the firm's own disclosures don't cover a category, or to spot-check disclosed figures against the consensus range.

The spread shown for each factor is the range across published sources for the sector — not Telstra's own values. A wide spread means the published sources disagree (use with caution); a tight spread is a well-established consensus. Telstra's own disclosed figures live on the Ratios tab. (Plotting where Telstra sits within each distribution is on the roadmap.)
