(13)To reduce the complexity and length of the reporting templates and ease considerably the reporting of undertakings under Delegated Regulation (EU) 2021/2178, reporting templates provided in that Delegated Regulation should be significantly shortened and simplified without losing essential information provided in those templates concerning the extent to which the activities of the reporting undertakings are associated with environmentally sustainable economic activities. Moreover, the specific templates provided in Annex XII to Delegated Regulation (EU) 2021/2178 related to the activities in the fossil gas and nuclear sectors should be deleted to reduce reporting burdens and to avoid duplication with information disclosed by non-financial undertakings in the templates provided in Annexe II to this Regulation. Non-financial undertakings should disclose the same categories of information with respect to their material activities in the fossil gas and nuclear sectors as for other sectors. To reduce the reporting burden for financial undertakings and to ensure consistency with taxonomy disclosures of their counterparties, it is necessary to amend Annexes IV, VI, VIII and X to that Regulation to ensure that financial undertakings disclose consistently their exposures to taxonomy-eligible or taxonomy-aligned activities in the fossil gas and nuclear sectors in aggregate form.
