This case note analyses the General Court’s judgment in Arysta Lifescience v EFSA (Case T-222/23), which addresses the tensions arising from the disclosure of the lists of co-formulant in the context of the EU risk assessment of pesticides. The decision consolidates the General Court’s interpretation of “information relating to emissions into the environment” under Article 6(1) of Aarhus Regulation, confirming its applicability to the list of co-formulants contained in representative products.
