| EU Taxonomy and SFDR | Not determined | Not assessed. | EnEfG; EDL-G; EU Taxonomy Regulation; SFDR |
3.Data quality and limitations
Rating: High — All carriers have complete records, stated area and fuel bases, costs and required supplier factors.
Statuses are screening indications from the entered data, not legal advice. Verify the promulgated statutes and individual exemptions with qualified professionals. An Energieausweis may only be issued by authorised issuers.
