Index consultations

Euronext Indices is committed to provide indices that respond to the best of its abilty to the needs of all stakeholders of its indices. In order to achieve this and in response to developments on the markets frequent feedback is sought among the known users of the indices. For major changes Euronext Indices will launch consultations from time to time via this page.

Each consultation will be open for at least 3 weeks.

A summary of the comments received will be published within 3 weeks after the consultation is closed. In principle the comments will be made public anonymously, indicating only the nature of person or institution providing the comment.

Taking into account the feedback received in the consultation, the Administrator will formulate a proposal for a rule change to the appropriate oversight committee for approval. As a rule such decision will be taken within 3 months after the decision.


Euronext would like to consult on proposed changes to the methodology of the CAC 40 ESG. The proposed changes cover the following elements of the methodology: 

  • the Index Universe 
  • The eligibility screening 
  • The  ‘verification of the impact objectives’ 

The aim of the changes is to ensure that the Index Methodology aligns with: 

  • the latest version of the Label ISR 
  • the guidelines established by ESMA for use of ESG and sustainability terms in fund names

Stakeholders will have till the 28th of June to react to the consultation. The new rules, if validated by Index Design and the Independent Supervisor of the Indices, will be implemented as of the September 2024 Review of the indices.
