The problem
Corporate carbon accounting still runs on spreadsheets
Multi-BU organizations manage regulated emissions data in disconnected workbooks - with no version control, no governed emission factors, and no audit trail. Regulators, investors and auditors have stopped accepting that.
4 sources
Ungoverned emission factors
EPA, IEA, DEFRA, API Compendium - different vintages in every BU, sometimes the wrong factor entirely. Consolidated totals nobody can defend.
0 audit trail
Chain of custody by email
Who changed what, when, and why lives in inbox archives and institutional memory. Verification engagements surface it as a major finding - every year.
3 regimes
Overlapping deadlines
SEC climate rules, EU CSRD and CDP land at once, with no workflow, no at-risk visibility, and review windows compressed to nothing.
The platform
One system of record, business unit to boardroom
Activity data flows in from every site; governed calculation turns it into defensible tCO₂e; workflow, audit trail and reporting carry it all the way to the regulator.

Scope 1 · Direct
Stationary & mobile combustion, flaring, venting, process and fugitive/LDAR emissions - captured at equipment level with guided, schema-driven forms.
Scope 2 · Energy
Purchased electricity, steam, heat and cooling - calculated with both location-based and market-based methods, reported side by side.
Scope 3 · Value chain
Category 1 (purchased goods & services) at launch via spend-based and activity-based methods - all 15 categories on the roadmap.
Versioned EF library
GHG Protocol, EPA, API Compendium, DEFRA and IPCC factors pre-seeded. Every factor versioned by effective date; strict BU-override → tenant → standard resolution.
Immutable snapshots
Every calculation freezes its inputs - factor version, GWP set, unit conversions, boundary approach - into a snapshot that is never rewritten.
Governed workflow
Draft → Submitted → In Review → Approved → Locked, with automated variance checks, documented rejections and credential-confirmed approvals.
Bulk import that forgives
Pre-configured templates, row-level validation, staged commits, partial imports and 30-day rollback - nothing lands in production unreviewed.
Role dashboards
Portfolio overview for managers, completion grid for reporters, evidence view for auditors - every user lands on the view built for their job.
Regulatory reports
GHG Protocol, ISO 14064-1, CDP, TCFD and GRI 305 outputs generated from approved-and-locked data only - with full generation metadata.
The workflow
Five states. Zero ambiguity.
Every submission moves through one canonical state machine - every transition timestamped, attributed and preserved in workflow history.
DraftReporters capture activity data with live tCO₂e preview and auto-saved drafts.
SubmittedCompleteness enforced - an incomplete inventory can't be submitted.
In ReviewManagers see anomaly flags, prior-period variance and attached evidence.
ApprovedCredential-confirmed approval, recorded to workflow history.
Locked Period finalized. Immutable. Edits blocked at the API layer, not just the UI.
REJECTED → returns to Draft with a documented reason. Nothing disappears.
The engine
Calculation you can put in front of a regulator
Multi-gas, unit-safe, asynchronous - and every result frozen the moment it's computed.
- All seven GHG species: CO₂, CH₄, N₂O, HFCs, PFCs, SF₆, NF₃ - calculated per gas, summed to tCO₂e
- IPCC AR4 / AR5 / AR6 GWP sets, configurable per tenant
- Canonical unit reference - conversions never rely on free-text strings
- Methane tracked separately in tCH₄ for OGMP 2.0 reporting
- Fixed-point decimal to 6 places - never floating point
- Impact preview before any bulk recalculation touches a locked year
EtCO₂e = Σ ( AD × EFgas × GWPgas )

The audit trail
Tamper-evident by construction
An append-only ledger where every entry is SHA-256 hash-chained to the one before it. Break one link and the daily integrity check tells you exactly where.
- Every create, update and workflow event logged - no exceptions, enforced at the database layer
- Full before/after state, actor, role, IP and UTC timestamp on every entry
- Reported figure → snapshot → factor version → activity record → source document, in three clicks
- Evidence packages exported for verifiers in one action

The people
Four roles. One version of the truth.
Admin
HEAD OF GHG REPORTING
Real-time status across every BU, one governed factor library, evidence packages in clicks. Admin overhead: 15h → 3h a week.
Data Manager
REGIONAL SUSTAINABILITY
A review queue with anomaly flags and prior-period variance already computed. A full-day review becomes ~45 min.
Data Reporter
FIELD OPERATIONS
Guided forms, automatic unit conversion, live calculation preview, drafts that survive interruptions. 3h → 35 min per period.
Auditor
EXTERNAL ASSURANCE
Read-only access to everything, frozen calculation snapshots, self-service evidence. Engagements end with zero major findings.
Compliance
Aligned with the frameworks that matter
Report templates and methodology built against the standards your regulators, investors and verifiers actually ask for.

Industries
Oil & Gas first. Every sector by design.
Nothing industry-specific is hardcoded - emission sources, calculation rules and factor libraries are configuration. We simply start where the accounting is hardest.
Oil & Gas
LAUNCH TEMPLATE40+ pre-configured source categories: stationary & mobile combustion, flaring by gas composition, venting, fugitive/LDAR by component type, process emissions, purchased energy and refrigerants - with OGMP 2.0 methane tiers.
Manufacturing
CONFIGURATION-READYUtilities
CONFIGURATION-READYTransportation
CONFIGURATION-READYReal Estate
CONFIGURATION-READYSecurity & trust
Enterprise-grade isolation, by default
Tenant isolation in depth
PostgreSQL row-level security, a request-context guard, independent ORM-level tenant filtering and role-and-node authorization - four independent layers between any two organizations.
Encryption everywhere
AES-256 at rest, TLS 1.3 in transit, MFA for privileged roles and enterprise SSO via OIDC/SAML.
Compliance posture
SOC 2 Type II design readiness, OWASP Top 10 coverage, quarterly penetration testing, WCAG 2.1 AA accessibility and a 99.9% uptime SLA.
Roadmap
Where the book goes next
Market entry
Full Scope 1/2 + Scope 3 Category 1, the O&G template, enterprise clients with 50+ BUs - and zero major findings across client verifications.
Horizontal expansion
Manufacturing, Utilities and Financial Services templates, all 15 Scope 3 categories, ERP/SCADA integration APIs and multi-language UI.
Intelligence & scale
AI-assisted anomaly detection and forecasting, carbon offset and SBTi target tracking, multi-region data residency at hundreds of tenants.
Before the first line of interface
The specification came first. All of it.
We didn't design GHG Book by shipping screens and patching the data model around them. Every table, every endpoint, every audit invariant and access-control boundary was specified, reviewed, and ratified - with the alternatives we rejected written down - before an interface existed. It's a slower way to start a product. It's also why an auditor will be able to trust what we build.
0architecture decisions logged, each with the alternatives we rejected
0adversarial specification reviews before a build began
0hardcoded categories or emission factors - every value is configurable data
0independent isolation layers, enforced at the database, not just the UI
