support the participation of civil society organisations in partner countries in their respective DAGs; 5. Reiterates its call for sufficient resources to conduct ex-ante, interim and ex-post assessments of trade agreements and to review the methodology used, including regarding cumulative effects, the impact on achieving the SDGs, and that on implementing the Paris Agreement; considers that the European Union should take the social, health and environmental impact of its trade relations and agreements into account more strongly when evaluating current and future scenarios, and stresses also the need for gender-disaggregated data; calls on the Commission to cooperate closely with the scientific departments of the UNCTAD and the OECD; 6. Notes that the conclusion of each new trade agreement can mean substantial revenue losses for the Union’s own-resources budget; calls on the Commission to accurately measure these losses and to provide Parliament with the respective figures for each agreement concluded; notes that the Member States retain 20 % of customs duties on imports from outside the Union as collection costs; supports the proposal of reducing this share to 10 % for the MFF period 2021-2027, to the benefit of the Union’s own resources budget; calls on the Commission and the Member States to increase their efforts against customs fraud; 7.

Reiterates that trade policy and development policies are complementary elements of the Union’s external policies, forming an integral part of the European Consensus on Development, and that aid effectiveness principles must also be applied to Aid for Trade; recalls the unfulfilled commitment by the Union and most of the Member States to increase their official development assistance (ODA) to 0.7 % of gross national income (GNI) by 2030, including allocating 20 % of the EU’s ODA to actions for social inclusion and human development and 0.2 % of the Union’s GNI to ODA for least developed countries; 9.
