Your letters of 14 June 2021 concerning the Farm to Fork objectives and the substitution principle

Dear Ms. Roynel and Mr. Muilerman, 

Thank you for your above-mentioned letters to Commissioner Kyriakides and Executive Vice-President Timmermans, who asked me to respond on their behalves. In your letters you urge the Commission to exclude any incorporation of the new EPPO standard PP 1/271 (3) ‘Guidance on efficacy aspects of comparative assessment’ from the envisaged revision of the principles for comparative assessment to be conducted for plant protection products containing active substances that are candidates for substitution.
