How to enter environmental data in Darwin

Create Data Points

Data points are the environmental measurements and activities that Darwin uses to calculate your biodiversity footprint. They represent everything from raw material purchases to energy consumption and land use.

Data Points table

Data Point Structure

Each data point contains:

Field	Description	Example
Label	Descriptive name	"Cow milk supply from Farm 1"
Value	Numeric measurement	6,000,000
Unit	Measurement unit	kg, m², kWh, t-CO2-Eq
Related Entity	Which entity this belongs to	"Farm 1"
Scope	Direct (1) or Upstream (3)	"3 - Upstream"
Type	Data category	Product/Materials, Pressures
Subtype	Specific classification	Procurement, Climate Change
Model Used	ecoinvent/EXIOBASE match	"cow milk (GLO)"

Add a Data Point

Navigate to Data Points

Go to Collect > All Data Points in the sidebar.

Click the Add Row

Click the + button at the bottom of the table to add a new row, or click in an empty area.

Enter Collection Data

Fill in the left section (Collection):

Label: A clear, descriptive name
Value: The numeric amount
Unit: Select the appropriate unit
Related Entity: Choose the entity this data belongs to
Scope: Select Scope 1 (direct) or Scope 3 (upstream/downstream)

Configure Modeling

Darwin will attempt to auto-match your data:

Type: Product/Materials, Pressures, or Commodity
Subtype: More specific categorization
Model Used: The ecoinvent or EXIOBASE process matched

Click on the Model Used field to search and select a different process if the auto-match isn't correct.

Set Contribution Rule

Choose how this data point contributes to the assessment:

Add-up: Adds to existing values (default for materials)
Replace: Replaces calculated values with your direct measurement
Replace (Propagation): For pressures that propagate through the supply chain

Data Types

Product/Materials

Physical goods and materials entering your supply chain:

Subtype	Description	Example Units
Procurement	Purchased materials	kg, t, m³
Sales/Production	Goods produced	kg, units

Pressures

Direct environmental impacts you've measured:

Pressure Type	Description	Units
Climate Change	GHG emissions	kg CO₂ Eq, t CO₂ Eq
Ecosystem Use	Land occupation/conversion	m², ha
Water Use	Water consumption/withdrawal	m³
Pollution	Chemical releases	kg, CTUe
Overfishing	Fish extraction	t
