Climate Impact X (CIX) is pleased to advise that a series of new features and enhancements have been introduced to the CIX Exchange platform, effective immediately. These updates are designed to improve transparency and workflow efficiency for market participants.

Summary of key enhancements:

1. Expiry handling for amended Good-Til-Cancelled (GTC) orders
2. Expanded on-platform news coverage with Carbon Pulse headlines
3. CIX CP1X-GM benchmark ticker on the trading screen
4. Project vintage-level ratings from BeZero and Calyx
5. Expanded Clear trade submission functionalities

1. Expiry handling for amended Good-Til-Cancelled (GTC) orders

When a Good-Til-Cancelled (GTC) order is amended, its expiry date will now automatically refresh to the maximum duration of 90 days, eliminating the need to recreate the order. Together with the 5-day expiry alert, users can manage their orders with greater ease.

2. Expanded on-platform news coverage with Carbon Pulse headlines

CIX has expanded its on-platform news coverage to include Carbon Pulse headlines, alongside existing QCI headlines. This provides market participants with broader access to carbon market news and context within the CIX Exchange platform.

3. CIX CP1X-GM benchmark ticker on the trading screen

CIX CP1X-GM benchmarks are now displayed in a ticker at the top of the trading screen. The ticker refreshes at the start of each trading day and whenever new benchmark updates are published intraday.

4. Project vintage-level ratings from BeZero and Calyx

Where available, ratings from supported providers, including BeZero and Calyx, are now mapped to specific project vintages, providing market participants with a more accurate view of the credits being assessed.

5. Expanded Clear trade submission functionalities

CIX has introduced several enhancements to the Clear trade submission workflow:

• Multi-currency support: Clear trades may now be submitted in USD , SGD, EUR and GBP. Available currencies will be displayed in the dropdown menu during trade submission. All fees will be charged in the currency selected.
• PoA instruments: Following the launch of Gold Standard Programme of Activities (PoA) instruments on CIX Exchange, Clear now supports PoA trade submissions. The specific underlier is selected at settlement, with one underlier supported per trade.
• CP1X-GM submissions: Clear now supports trade submissions for CP1X-GM, CIX’s standardised spot contract for CORSIA Phase 1 eligible credits. For Clear submissions, the underlier is selected at settlement, with one underlier supported per trade. Trade size should be entered in tonnes, not lots as on CIX Exchange.

Additional user interface enhancements

In addition, CIX has introduced a range of user interface (UI) improvements as part of this roll out. This includes allowing users to download consolidated Holdings reports for any chosen date, retain workspace preferences across view switches and logins, as well as clearer identification of the “Show History” button for CIX Intelligence Price History column, amongst others.

All new features and enhancements announced in this notice are live on the CIX Exchange platformCIX Operational Procedures have been updated to reflect these enhancements and are available here.
