Platts to discontinue Nature-Based Avoidance, Southeast Asia vintage spread assessments Dec. 1

Platts, part of S&P Global Energy, will discontinue the publication of its Nature-Based Avoidance, Southeast Asia Current Year vintage year spread price assessments, effective Dec. 1, 2026.

Platts proposed this change via a subscriber note published Oct. 12 here. This discontinuation reflects the limited activity for specific vintages of carbon credits expressed as a discount or premium to the current year, and inconsistent issuance schedules for more recent credits.

The publication of these vintage year spread assessments for the Nature-based avoidance, Southeast Asia Current Year price assessment was suspended in August 2025. Details are available here.

The spread assessments that will be impacted by this decision are as follows:
