  • Following market consultation, Climate Impact X (CIX) has decided to reduce the frequency of publication of the Nature X, ARR X, and Cookstoves X benchmarks, along with the associated price assessments.

    The decision follows a proposal notice and a public consultation that commenced on 30 January 2026. The proposal was made following a routine evaluation of the level of activity and relevance of these price assessments. Market feedback received during the consultation period was supportive of the final decision to reduce the publication frequency of the CIX Nature X (CNX), CIX ARR X (CAX), and CIX Cookstoves X (CCX) benchmarks to a monthly basis. For CCX contracts, it includes the Gold Standard Least Developed Countries (CCX-LG), Gold Standard Developing Countries (CCX-DG), Verra Least Developed Countries (CCX-LV), and Verra Developing Countries (CCX-DV) contracts.

    Notwithstanding any decision to amend the publication frequency, trading of CIX Nature X (CNX), CIX ARR X (CAX), and CIX Cookstoves X (CCX) contracts will continue to be available on the CIX Exchange. CIX remains open to the publication of new benchmarks to serve the carbon market and welcomes ongoing and additional feedback about their design.

    Following the decision, below price assessments will be published monthly as of 11 May 2026.

    Member firms may elect to simplify maker–checker process flows to require only a single user approval. In addition, CIX Admin rights have been extended to allow the CIX Operations team to perform all key actions on behalf of clients, when requested. 

    In addition, CIX has introduced a range of user interface (UI) improvements as part of this roll out. This includes allowing users to collapse the ‘Order Entry’ and ‘Order Management’ panels, as well as download and export holdings across all accounts into a single file, amongst others.
