(16)To enhance investor confidence, compliance with the technical screening criteria related to fossil gas activities should be verified by an independent third party. To ensure an impartial and diligent verification of compliance, the independent third-party should have the resources and expertise to perform that verification, be independent to avoid any conflict of interest with the owner or the funder, and should not be involved in the development or operation of such fossil gas activities. In addition to the verification mechanism, financial and non-financial undertakings may be subject to specific verification requirements provided in other Union legislation on sustainable finance that cover compliance with the technical screening criteria. In accordance with Article 26(1), point (c), of Regulation (EU) 2020/852, the Commission should review the provisions required for setting up verification mechanisms of compliance with the criteria set out in that Regulation.
