The Platform

One model. Every emission source. One auditable output.

Circulyft's calculation engine ingests data from your utility providers, ERP systems, freight carriers, and suppliers — applying EPA, IPCC, and GHG Protocol emission factors at the line-item level. The output is a complete Scope 1-3 GHG inventory with a source-cited audit trail your statutory auditor can open and verify record by record.

Data Ingestion

Five input methods — structured API to legacy PDF

Circulyft normalises every input format — whether it's a live smart meter API feed or a utility PDF invoice with a non-standard layout. No manual re-entry, no column-mapping work for you.

Utility API
Direct smart meter connections. Real-time kWh, gas volume, and demand data — no manual exports.
ERP Connector
SAP, Oracle, and NetSuite connectors via REST. Pull purchase orders, fuel records, and asset data automatically.
Freight APIs
Carrier API integrations pull shipment weight, distance, and mode — calculating transport emissions at the lane level.
PDF Invoice Parsing
Upload utility or fuel invoices as PDFs. Our parser extracts meter reads, consumption figures, and billing periods.
CSV Upload
Standardised CSV templates for any data that doesn't have a live integration yet. Column mapping is automatic.
Utility Invoice — Parsed Extracted
Billing period Oct 1 – Oct 31, 2025
Natural gas consumed 48,200 therms
Electricity consumed 312,500 kWh
Emission factor applied EPA 2024 — NG combustion
Scope 1 output 254.8 tCO2e
Scope 2 output 141.6 tCO2e
Calculation Engine

Line-item precision, not category estimates

Every emission figure is traceable to a specific activity, emission factor, and methodology — not averaged across departments.

EPA, IPCC, and GHG Protocol factors
Emission factors sourced from authoritative datasets, version-controlled and updated annually. Your auditor knows exactly which version was used.
Market-based and location-based Scope 2
Both methods calculated in parallel from the same utility invoice data. GHG Protocol dual-reporting requirement met automatically.
Scope 3 category allocation
All 15 GHG Protocol Scope 3 categories. Upstream and downstream. Spend-based, physical activity, and supplier-specific methods applied per category.
Natural gas: 48,200 therms × EPA NG-2024: 53.06 kgCO2/MMBtu
÷ Unit conversion: 0.1 MMBtu/therm
→ 255.8 tCO2e — Scope 1
Electricity: 312,500 kWh × eGRID MRO 2024: 0.4536 kgCO2/kWh
→ 141.8 tCO2e — Scope 2 (location)
Audit Trail

Your auditor will ask for this. We have it.

Every calculation is traceable: data source, emission factor version, calculation date, and methodology reference. Exportable as a structured appendix.

Report Output

Not just a PDF — structured data your auditor can re-run

Circulyft doesn't write your sustainability narrative or conduct your limited assurance review — it produces the verified GHG dataset and pre-formatted disclosure tables your statutory auditor needs to sign off. Export once and cover CSRD, GHG Protocol Corporate Standard, GRI 305, and SEC climate disclosure requirements from the same underlying inventory.

CSRD / ESRS E1
CSRD Climate Report
ESRS E1 disclosure template with GHG inventory, climate targets narrative, and transition plan inputs. Linked to source data.
GHG Protocol
Corporate Standard Report
Scope 1, 2 (market + location), and 3 inventory following GHG Protocol Corporate Standard. Dual-method Scope 2 included.
GRI 305
GRI Emissions Disclosures
Pre-formatted GRI 305-1, 305-2, and 305-3 disclosures with all required contextual information and intensity metrics.
SEC Climate Rule
SEC Climate Disclosure
Scope 1, 2, and material Scope 3 formatted for SEC annual report integration. Financial materiality assessment included.
Export Formats
PDF, Excel, and API
Structured PDF for statutory filing, Excel workbook with calculation backing, and REST API endpoint for BI tool integration.

See your Scope 3 inventory built from your actual data

In a 30-minute demo, we connect to one of your existing data sources — utility API, ERP export, or CSV — and show you what your Scope 1-3 GHG figures look like from real data. You see the audit trail before you make any commitment.
