Everything your inventory needs.

Built for sustainability professionals. Designed for third-party verifiers.

Guided inventory wizard
Step-by-step data collection across all Scope 1, 2, and 3 categories. No blank spreadsheets. No guessing which sources to include.
Real emission factors
IPCC AR6 GWP values throughout. IEA 2024 grid electricity factors. DEFRA 2024 travel and freight factors. Auto-converts to AR4 on CARB export.
Immutable audit trail
Every data entry, edit, and deletion is logged with user, timestamp, and previous value. Written by the database — not the application. Cannot be altered.
Multi-framework export
One inventory exports to: CARB SB 253 template, CDP C6 and C7, ESRS E1-6, EcoVadis, GRI 305, and IFRS S2 simultaneously.
Scope 3 — all 15 categories
Primary data collection, spend-based, hybrid, and supplier-specific methods. CDP C12 supplier engagement. CS3D value chain mapping.
Assurance-ready package
Pre-formatted data room for your verifier: methodology documentation, emission factor citations, uncertainty assessment, and boundary justification.
Greenwashing risk — Canada

Every carbon claim now needs proof behind it.

Canada's Competition Act now targets unsubstantiated environmental claims. If you state “net zero,” “carbon neutral,” or “emissions reduced by X%,” the burden is on you to prove it — under a reverse-onus standard, the company making the claim must show it is adequately and properly substantiated, not the regulator. An audit-trailed GHG inventory is that proof.

✓Reverse onus — you must substantiate the claim
✓Penalties up to $10M or 3% of global revenue
✓Applies to marketing, websites, and reports
✓ThemisIQ gives every figure a documented, defensible basis
Claim vs. proof
"We are carbon neutral"
Needs: Scope 1 + 2 inventory with cited emission factors
"Emissions down 30%"
Needs: Prior-year baseline + current inventory, same methodology
"Science-based target"
Needs: Verified baseline inventory - the foundation for any target
"Low-carbon operations"
Needs: Intensity figures benchmarked and source-documented
Competition Act (Bill C-59, 2024; amended by C-15, 2026). Requirements are evolving and subject to a constitutional challenge — confirm your obligations with counsel.
