Platts to roll reflected vintages for several carbon credit assessments July 1

Platts, part of S&P Global Energy, will roll the vintages reflected by some of its carbon credit assessments July 1, 2026.

Platts rolls the vintages reflected in a number of its carbon credit assessments on the first working day of the third quarter of each year. Vintages roll forward by one year on this date. Platts defines a range of vintages reflected in its assessments, dependent on liquidity and fungibility. The roll means affected assessments will reflect more recent vintages.

See below a summary of the assessments affected and vintages that will be reflected from July 1, 2026:

Other carbon credit assessments reflect a defined range of vintages with no annual roll. Platts coverage of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) continues to reflect vintages in line with the International Civil Aviation Organization (ICAO) guidelines.
