Lists are not connected to a specific year and can thus be used across many years. Lists can be updated over time. For example, more precise figures may be released based on the latest scientific research. It is best to update lists before a reporting period rather than during.

Assigning a version number to a list allows metadata to be adjusted and for these adjustments to be recorded.

The two values can have different validity periods:

 List item with two values. List item Germany - Diesel kg CO2/kWh. Values: 0.2675, 0.2645.

Add list items

When uploading a list, there are three ways in which a list can be processed by Position Green:

• Ignore duplicates - All list items will be inserted.
• Update and replace duplicates - New list items will be inserted. All matched existing list items will have their current values updated.
• Update and insert new value from today's date - New list items will be inserted. All matched existing list items will have new values added. This will be valid from the upload date.
