GHG Protocol: Data Requirements

Use this guide as a reference when planning your data integration with Dcycle. For each emission category, we list the exact fields Dcycle needs, the typical source systems where that data lives, and the recommended integration method.

Who is this for?This guide is designed for IT and data engineering teams who are planning how to feed data into Dcycle — whether through APIs, bulk CSV uploads, or PDF/OCR processing. Share it with your technical team so they can map their internal data sources to Dcycle’s requirements.

How Dcycle Fits in Your Data Architecture

Dcycle acts as a data processing and calculation engine that sits between your raw data sources and your environmental reporting outputs. You send us raw or semi-structured data, and we handle normalization, enrichment, calculation, and reporting.

You don’t need to clean or transform data before sending it to Dcycle.Send us the rawest data you have — PDFs, CSVs from your ERP, fuel card exports. Dcycle handles OCR, normalization, unit conversion, and emission factor matching. This means your Data Lake integration can sit after Dcycle: pull the enriched, calculated results back via our APIs into your Gold layer.

Integration Methods

Dcycle supports four ways to ingest data. Choose the one that best fits each data source:

Method	Best for	Automation	Setup effort
REST API	ERP integrations, real-time data feeds, programmatic access	Full	Medium
Bulk CSV upload	Periodic data dumps, spreadsheet-based workflows	Semi-auto	Low
PDF / file upload	Invoices, utility bills, fuel receipts	Full (OCR)	Low
Manual entry (App)	One-off data, qualitative estimates, small datasets	Manual	None

Recommended approach for data lake architectures:

Configure your Bronze layer ingestion to collect raw data from source systems
Send that raw data to Dcycle via API or CSV (no cleaning needed)
Pull enriched + calculated results from Dcycle’s APIs back into your Gold layer
Build dashboards and reports on top of the Gold layer

This way Dcycle handles all the Silver-layer transformations (OCR, normalization, enrichment, calculation) and you retain full control of the data in your own infrastructure.

Manual → Use-phase data typically comes from R&D or product engineering

Company Structure (Prerequisite)

Before loading emission data, configure your organizational hierarchy.

`fuel_types`	list	✅	Fuels consumed at this facility	Natural gas, diesel, etc.

Required for: All Scope 1 and Scope 2 calculations. Each invoice/consumption record is linked to a facility.

📋 Parent-Child Relationships (Groups)

Field	Type	Required	Description	Example
`share`	number	✅	Ownership percentage (0-1)	`0.75` (75%)
`investment_scopes`	list	✅	Scopes to consolidate	`[1, 2, 3]`

`status`	string	✅	Must be `"accepted"` to consolidate	`"accepted"`

Required for: Multi-entity organizations (holding companies, groups with subsidiaries).

Summary: Data Source Mapping

Use this table to map your internal systems to Dcycle data requirements:

GHG Category	Data Needed	Typical Source	Integration	Dcycle Adds
S1: Stationary combustion	Fuel type + quantity + dates	Utility invoices (PDF), ERP	PDF/API/CSV	EF selection, unit conversion
S1: Refrigerants	Refrigerant type + kg recharged	HVAC maintenance records	CSV/API	GWP lookup
S1: Vehicles	License plate + fuel type + liters/km	Fuel cards, fleet system	CSV/API	EF by fuel and vehicle type
S1: Wastewater	Daily flow + BOD + nitrogen + biogas	SCADA, laboratory (LIMS)	API/CSV	CH₄ + N₂O calculation
S1: Process	Process type + quantity	Production records, permits	API/CSV	Custom EF application
S2: Electricity	kWh + dates + supplier (optional)	Electricity bills, Datadis	PDF/API/CSV	Dual location + market calc
S2: District heat/cool	kWh or MJ consumed	Provider invoices	API/CSV	EF selection
S3.1: Purchases	€ or kg + category + supplier country	ERP, accounts payable	CSV/API	Sector enrichment, EF match
S3.2: Capital goods	Same as S3.1	Asset register, capex records	CSV/API	Same as S3.1
S3.3: Fuel & energy	(automatic from S1 + S2 data)	—	—	Fully automatic
S3.4/9: Transport	Origin + destination + weight + mode	TMS, logistics ERP	CSV/API	Geocoding, km calculation
S3.5: Waste	LER code + kg + treatment method	Waste manager reports	CSV/API	EF by waste + treatment
S3.6: Business travel	Origin + destination + mode + class	Travel agency, expense tool	CSV/API	Distance calc, EF by mode
S3.7: Commuting	Employee + transport mode + km	HR system + survey	CSV/API	EF by mode, work-day calc
S3.11: Use of sold products	Lifespan + energy consumption + units sold by country	Product specs, ERP/CRM sales	CSV/API	Country-specific EF, lifespan calc

Progressive approach: start broad, then deepen

Month 1: Upload PDFs (invoices, bills) + basic CSVs from ERP (purchases, fuel cards)
Month 2-3: Set up API integrations for high-volume data (logistics, vehicles, electricity)
Month 4+: Engage suppliers for EPDs, connect IoT/SCADA for real-time data
Ongoing: Pull calculated results back to your Data Lake via Dcycle APIs

You don’t need 100% automation on day one. Dcycle is designed to work with whatever data format you have today and improve over time.
