Delegations are working groups set up within the ESEC to study specific problems and issues beyond the scope of individual sections.
- The Delegation for the Overseas was established as part of the ESEC in November 2010, reflecting a strong commitment to take into account the concerns, contributions and specific characteristics of French overseas territories. The Delegation for the Overseas is tasked with publishing studies on overseas issues and contributing to the work of other ESEC working groups. The delegation also organises and participates in events and debates on overseas matters.
- The Delegation for Long-range Planning and Evaluation of Public Policies was set up in November 2010 to give the ESEC a long-range planning body similar to that of the French Senate. Its goal is to foresee the key economic, social and environmental challenges ahead and help assess public policies in line with the responsibilities given to the Council under the organic law of 28 June 2010.
- Established in February 2000 and modelled on counterpart delegations in the French National Assembly and the French Senate, with which it has close relations, the Delegation for Women's Rights and Equal Opportunity monitors and promotes awareness of such matters in initiatives handled by the ESEC. The delegation also draws up specific studies based on the drive to ensure gender equality.
