LEO – Header Definitions
This page explains all headers available in the LEO (Log Emissions Overview) export. The export contains a mix of user-entered data, system metadata, and derived/calculated values. Some numeric values may appear proportionally split when filters are applied (monthly slicing). To understand the split better please see here
Video Walkthrough:
1. Identification & Core Metadata
Log ID
Unique identifier of the log used to group multiple log entries for easier categorization and filtering.
Log entry ID
Unique identifier of the individual log entry instance. Useful for audits and debugging.
Log entry title
Optional input - text name of log entry to describe a log entry in plain language and more detail. If left empty, the subcategory name will be used as the title
Log description
Optional input - custom description for the created log for additional detail
2. Categorization & Scope
Log category
Includes the name of the category selected (e.g. Company vehicles, Office goods, Purchased services etc)
Log subcategory
More granular classification within the Cozero log category (e.g within log category “Company vehicles” , the subcategory can be e.g. “Delivery vehicle” or “Passenger vehicle”).
Scope and subcategory
Scope classification (Scope 1, Scope 2, Scope 3.4 etc).
3. Business & Organisational Context
Business Activity
Describes the underlying business activity identified by the Cozero database to calculate emissions (e.g. 'Biodiesel' for Delivery vehicles type emissions, 'country residual or grid mix' for electricity emissions etc).
Business unit
Name of the business unit associated with the log. Can be any BU chosen while creating the log by user. This has to be part of BUs already created within the platform before the log creation.
Responsible
Assigned owner or user responsible for the log entry.
4. Data Quality & Status
Data quality
Indicates the quality level of the data based on completeness and methodology. Data quality can be unknown or of unverified origin, proxy, secondary or primary.
Calculation method
Method used to calculate emissions (e.g. spend-based, activity-based).
Calculation status
Indicates whether the calculation was completed successfully, is blocked, in calculation, failed etc.
From bulk import
File name of the bulk import (if the log is created via bulk import).
5. Location & Territory
Location
Name of the location associated with the log.
Location tags
Tags assigned to the location for grouping and filtering (by user)
Territory
Country/geographical region associated with the log (used for EF selection).
6. Period & Timestamps
Period start
Start date of the activities responsible for emissions calculated for the log.
Period end
End date of the activities responsible for emissions calculated for the log.
Created at
Timestamp indicating when the log was created.
7. Tags & Attachments
Files
Files attached to the log entry.
Organization tags
Organization related tags used for reporting, filtering or sorting. (optional value added by user)
Product tags
Product-related tags used for categorisation and reporting. (optional value added by user)
8. Supplier Information
Supplier
Supplier associated with the log entry (if applicable).
9. Emission Factor Details
Emission factor ID
Unique identifier of the emission factor used. (internal to Cozero)
Emission factor description
Description of the emission factor used for calculation.
Emission factor source
Dataset or source of the emission factor (e.g. DEFRA, EPA).
Emission factor territory
Geographical applicability of the emission factor.
Emission factor validity year
Reference year of the emission factor.
Emission factor unit
Unit used by the emission factor.
Global warming potential version
GWP version used for the calculation (e.g. AR5, AR6).
Emission type
Indicates whether emissions are upstream/downstream electricity losses, Upstream fuel, biogenic, etc.
10. Input Values
Merged input value
Final input value used for the calculation after normalization.
Input as entered 1–10
Raw input values exactly as provided by the user.
Note: Multiple input columns exist to support complex activities requiring more than one input parameter.
11. Emissions & Energy Outputs
Emissions (tCO₂e)
Total calculated emissions in tonnes of CO₂ equivalent.
Location-based emissions (tCO₂e)
Emissions calculated using location-based methodology (where applicable).
CBAM emissions (tCO₂e)
Emissions relevant for CBAM reporting.
Biogenic emissions (tCO₂e)
Emissions classified as biogenic.
Energy consumption (kWh)
Energy consumption associated with the log (if applicable).
Energy type
Type of energy consumed (e.g. electricity, gas).
12. Financial Data
Spend
Spend amount associated with the log entry.
Important Notes
- Period filters may proportionally split values across months (monthly slicing).
- Export values reflect the filtered view (based on period selection), which may or may not be exactly equal to the original log.
