Energiföretagen
Source reference hasn't been consistent with other emission factor sources, where the year in parentheses should refer to the year of publication. This source has used the year reference to what year the data refers to, i.e. previous references of e.g. "Energiföretagen (2023)" should have been "Energiföretagen (2024)" as that is when the data was published. This has been updated and adjusted in annual 2025 update. Please note that emission factors remain unchanged.
