Bugfixes (electricity module)

Two issues related to the calculation of individual emission factors in the electricity module have been resolved in release 1.54.1:

• Individual emission factor with a value of zero
  It is now possible to enter an individual emission factor with a value of zero without triggering incorrect CO2e calculations. Previously, this led to an incorrect result, as a location-based electricity mix was incorrectly applied instead.

• Renewable of nuclear energy share set to 0% 
  If an individual emission factor was used and either the renewable or nuclear energy share was set to 0%, the CO2e calculation was incorrect.  

Important❗In both cases, please edit the affected activities, verify all input values, and trigger the calculation again to ensure accurate results. 

The fix currently applies to Scope 2. The update for Scope 3 will follow in an upcoming release.
