Platts to change publication schedule for carbon-accounted iron ore assessment

Platts, part of S&P Global Commodity Insights, will change the publication schedule for its daily carbon-accounted iron ore and carbon intensity premium assessments, effective June 2.

The Carbon-Accounted IODEX (CAIAA00) and IODEX Carbon Intensity Premium (CAIAB00) will follow the Singapore and US publication calendars. The assessments will not be published on a holiday in either location.

The change follows that to the publication schedule of the Platts Carbon Removal Credit assessment (ACRCA00) to one based on the US publication calendar, communicated in the May 5(opens in a new tab) subscriber note.

The Platts CRC assessment is an input to the IODEX Carbon Intensity Premium via the formula: IODEX Carbon Intensity Premium = IODEX Carbon Intensity (CAIAG00)/1,000 to convert from kilograms to metric tons * Platts CRC (ACRCA00)

The affected symbols are:
