(ii) were undertaken by a person with appropriate expertise who is not the supplier or a connected person of the supplier;
(b) be prepared by a person with appropriate expertise who is not the supplier or a connected person of the supplier and in accordance with the requirements for limited assurance engagements prescribed in ISAE 3000, or an equivalent standard (“the verifier”);
(c) consider whether the systems used to collate and report information relating to the compliance of sustainable aviation fuel with the sustainability criteria are likely to produce relevant data which is reasonably accurate and reliable and whether there are controls in place to help protect against material misstatements due to fraud or error;
(d) where the verifier intends to use as evidence work performed by the supplier or another party, consider the frequency and methodology of sampling used by that party and the robustness of the relevant data; and
(e) state whether anything has come to the verifier’s attention to indicate that—
(i) the relevant data has not been prepared in accordance with any guidance produced by the Administrator under article 14(2)(b); and
(ii) the information provided by the supplier under article 11 or 12 for the sustainable aviation fuel covered by the application is not accurate.
(2) The requirements for a verifier’s declaration are that it must confirm that—
(a) the assurance procedures used in the making of the declaration met the requirements for reasonable assurance engagements prescribed in ISAE 3000, or an equivalent standard; and
(b) the information related to an amount of sustainable aviation fuel required by the Administrator under article 11(1)(a) to (c) is reasonably accurate.
(3) In paragraph (1)—
“ISAE 3000” means the International Standard on Assurance Engagements 3000 promulgated by the International Federation of Accountants; and
“relevant data” means—
(a) the information referred to in article 16(3)(c); and
(b) any other information or data on which that information is based.
(4) If the Administrator requires a supplier to produce a verifier’s assurance report under article 11(4), then paragraph (1) has effect as if for “limited assurance engagements”, in both places where the words occur, there were substituted “limited assurance engagements or, if the Administrator requires, reasonable assurance engagements”.
