Each of the 22 Annexes to the EEA Agreement covers a specific sector, or area of law (e.g. Energy, Social Security, Financial Services, etc). A sectoral adaptation is an adaptation applicable to all acts within an Annex or a Chapter of an Annex.
Sectoral adaptations address challenges which arise frequently within specific sectors of legislation (such as the relevance of legislation within a particular sector to a specific EFTA State or the tasks of an EU agency under the EEA Agreement) and which are not already covered by the horizontal adaptations in Protocol 1. Acts incorporated into the Annex or Chapter of an Annex to which a sectoral adaptation applies are adapted accordingly. Where a sectoral adaptation applies, it is not necessary to repeat it in specific adaptations to individual acts within the same Annex or Chapter of an Annex.
Sectoral adaptations can be found in Annexes I (and Chapters I, II and III thereof), II (and Chapters XII, XIII and XXVII thereof), V, VI, VII, VIII, IX, XII, XIII, XIV, XV, XVI, XVII, XIX, XX, XXI and XXII and Protocol 47 to the EEA Agreement.
