Last modified: 23 Jul 2025

Basic info

Item in the Portlet center
Description	You can display your CO2 compensation values at the PORTFOLIO LEVEL or SYSTEM LEVEL.
Prerequisites	At least one system must be set up.
Portlet properties	Portfolio portlet: The portlet can be added at the PORTFOLIO LEVEL. System portlet: The portlet can be added at the SYSTEM LEVEL. Dynamic portlet: The portlet is updated when you select a different system name from the systems list.
Further details	By default, VCOM applies an emission factor for the country in which the system is located. The value is based on this database: Our World in Data. If no country-specific value is available, the global average is applied. You can configure a different value if desired.

Formula

If, for example, the emission factor is 0.596, the values are calculated as follows:

CO₂ savings = 0.596 * generated kWh

This means the kWh generated by your entire portfolio or system to date.

Planted trees = CO₂ savings in kg / 10.55

10.55 kg CO₂ savings are equivalent to one tree.
