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

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

This proposal 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 would be impacted by this proposed change are as follows:

Platts also proposes to discontinue the publication of currency conversions of the above spreads:

Before the suspension in August 2025, all symbols above were published in Carbon Markets Daily and on the fixed pages CMA2001, ETA2001, CMA2002, ETA2002, CMA2003, ETA2003, CMA2004, ETA2004, CMA2005, ETA2005, CMA2006, ETA2006, CMA2007, ETA2007, CMA2008, ETA2008, CMA2009, ETA2009, CMA2011, and ETA2011.
