Scope 3 Coverage Calculator
Scope 3 coverage with formula, benchmark (100 %) and improvement framing — ESG-questionnaire ready.
GHG Protocol defines 15 Scope 3 categories; materiality screening typically flags 5–9 for a given business. Coverage = measured ÷ material. SBTi requires Scope 3 targets when it exceeds 40% of total footprint — know your coverage before committing.
Scope 3 coverage = categories measured ÷ material categories × 100. Disclose the methodology alongside the number — comparability is what makes an ESG metric worth reporting, and year-on-year trend beats any single value.
Screening-level estimate using published average emission factors. Audited disclosures (BRSR, GRI, CDP) require primary activity data and verified factors — confirm with your sustainability auditor.

Frequently asked questions
Why do ESG metrics need a stated methodology?+
Because the same words hide different math: 'attrition' with or without contract staff, 'training hours' with or without e-learning, differ 2×. Comparability — across your years and against peers — is what makes a metric worth reporting; the formula line here is meant to be published alongside the number.
Where do the benchmarks come from?+
Published disclosure medians, regulatory norms and sector reports — indicative anchors, not league tables. Your sector, scale and geography shift what 'good' means; use the benchmark to know if you're roughly lean or heavy, and your own trend for the real story.
How often should this metric be computed?+
Monthly or quarterly for management, annually for disclosure — with the same method every time. The register tools on this site exist precisely to make the annual number an addition problem instead of an archaeology project.
What if my number is far worse than the benchmark?+
That's the metric working. Diagnose the denominator first (is the data right?), then the drivers — the improvement row shows what a 20% fix looks like. Disclosure-wise, a poor number with a credible plan reads better than silence; raters score trajectory and honesty.
