Scope 3 Boundary Mapper
Example session with this skill installed
Use $scope-3-boundary-mapper for an electronics manufacturer with supplier spend, inbound freight paid by us, capital equipment, employee commuting, product electricity use, take-back and recycling, and a minority investment. Route every activity across the 15 Scope 3 categories, identify Scope 1/2 overlaps and double-counting risks, state exclusions and missing boundary evidence, and build a factor-ready data request. Do not calculate emissions.
- Read your context and instructions
- Compiled the scope 3 boundary
Boundary summary
Seven value-chain activity families were supplied. The current inventory is not ready for quantification because inbound freight may be duplicated between purchased-goods spend and Category 4 activity data, and the minority investment lacks the organizational-boundary and proportional-share evidence needed for Category 15 routing. No emissions total is calculated.
Category routing
- Category 1 Purchased goods and services: supplier spend retained, with freight elements flagged for separation.
- Category 2 Capital goods: capital equipment retained; depreciation is not activity data.
- Category 4 Upstream transportation: inbound freight conditionally routed pending Incoterms and payer/control evidence.
- Category 7 Employee commuting: included; mode, distance, frequency, and workforce coverage missing.
- Category 11 Use of sold products: product electricity use included; lifetime and regional grid assumptions missing.
- Category 12 End-of-life treatment: take-back and recycling included without assuming treatment outcome.
- Category 15 Investments: DECISION REQUIRED — ownership share, asset class, and consolidation treatment missing.
Controls
The Category 1/4 overlap is OPEN. Scope 1/2 overlap checks require owned-fleet and facility-energy evidence. Remaining categories are marked not evidenced, not automatically excluded.
Priority data request
Obtain the reporting boundary memo, supplier-spend account mapping, Incoterms and freight invoices, capital asset register, commuting survey basis, product lifetime and sales-region data, take-back mass flows, and investment classification evidence.

About this skill
Scope 3 Boundary Mapper turns a company activity inventory into a traceable GHG Protocol boundary ledger before carbon calculations begin. It freezes the organizational and reporting boundary, normalizes value-chain activities, routes each activity across all 15 Scope 3 categories, applies minimum-boundary and mutual-exclusivity checks, exposes Scope 1/2 overlaps and unsupported exclusions, and produces a priority-ranked data request ready for quantification. The package includes a complete electronics-manufacturer case, machine-readable JSON, deterministic validation, forward tests, official-source notes, and a six-page buyer guide. It does not invent emissions totals, factors, targets, assurance conclusions, company comparisons, or legal disclosure decisions.
