What metrics are for
Metrics are the denominators you use to calculate emission intensity, such as emissions per square foot, per employee, per unit produced, or per dollar of revenue. Common metrics:
Floor area or square footage
Full-time employees
Production volume
Revenue
What a metric includes
Field | Description | Example |
name | The metric's identifier |
|
title | Display name | Office Size |
tag_name | The tag or trait it applies to, written as |
|
unit | Unit of measure |
|
value | The number | 42000 |
measurement_interval | How often it is measured |
|
measured_at_period | Which period the value is for |
|
A metric is identified by its name, tag and period together. That means you can record floor_area for the same facility in 2024 and 2025 as separate values.
Attaching to a tag or a trait
A metric can attach to a tag, such as a single facility, or to a trait, such as every facility in a region. Both use the type:name format, for example facility:denver-office or region:west.
How long a metric value applies
A metric value stays valid until a newer value is entered. You don't need to re-enter a metric every year if it hasn't changed.
For example, if you enter a floor area of 42,000 sq ft for year[2023] and nothing for 2024, Measure uses 42,000 sq ft for 2024 as well. If you later enter 45,000 sq ft for year[2025], that value applies from 2025 onward, and 2023 and 2024 keep the original 42,000 sq ft.
