Module reference · Scope 1 and 3
Emission Data
Every direct and value-chain emission source that isn't purchased energy or waste: fuel, vehicles, refrigerants, industrial processes, agriculture, land and travel. Each category has its own form because a litre of diesel and a herd of cattle need different inputs.
- Scopes
- 1, 3, and outside-of-scopes (biogenic and land removals)
- Entry
- Manual forms per category, or the Emission upload template
- Result
- One calculated row per gas stream, with provenance
- Factor sources
- UK DEFRA, US EPA, IPCC, Canada ECCC, in your order
What the module covers
Emission Data is the largest module. Categories are grouped by theme, and each maps to a calculator in the engine. The scope of a category is fixed by the calculator, never guessed from the size of a result.
| Theme | Examples | Scope |
|---|---|---|
| Combustion and direct operations | Stationary and mobile combustion, refrigerant and fugitive leaks, coal, oil and gas, operated landfill | 1 |
| Industrial processes | Cement, lime, ammonia, steel, electronics, ODS substitutes, SF₆ | 1 |
| Agriculture | Enteric fermentation, manure, soils, lime and urea, peat | 1 |
| Land use and removals | Forest land, settlement trees, land conversion, flooded land, harvested wood | Outside scopes |
| Value chain | Business travel, freight, hotel stays, materials, spend-based purchases, water supply and treatment | 3 |
The full list is in the User Guide
Every category with a one-line description is in Emission Data in the User Guide. How each is calculated is in Methodology.
Anatomy of a record
| Field | Holds | Notes |
|---|---|---|
| Category and activity | What kind of emission source | Decides the form and the calculator |
| Quantity and unit | How much | Converted exactly or refused; see Units |
| Facility | Where | Its country (and province for Canada) can decide the factor |
| Reporting year | Which period | One is active; new records default to it |
| Transaction date | When | Selects the factor edition valid on that date |
| Upload source | Where the record came from | A file, or an auto-created "Manual Entry" group; a Manual Group batches several entries |
What a calculation produces
Each calculated row carries CO₂, CH₄ and N₂O individually, a CO₂e figure under the organisation's GWP set (or the publisher's own pre-calculated CO₂e), the scope, and a link to the exact factor row used.
Direct row
Combustion or process emissions, in the record's scope.
Upstream and loss rows
Well-to-tank and similar, as separate rows when you enable them.
Biogenic row
Biogenic CO₂ reported outside the scopes.
Error row
If the record cannot be calculated, the reason, kept visible rather than dropped.
