Platts to discontinue Decarbonization Index, Sept 30

Platts, part of S&P Global Commodity Insights, will discontinue the Platts Decarbonization Index (ABZIA00) and the corresponding monthly average (ABZIA03) effective Sept. 30, 2025.

This follows a proposal published on Aug. 15, available here.

The daily index represents the theoretical cost to offset emissions using credits from a basket of sought-after classifications within the Voluntary Carbon Market (VCM).

The index uses a weighted average of some key Platts price assessments for the Voluntary Carbon Market, which are weighted based on annual retirements data reviewed each year.

Platts is discontinuing this index due to changing market fundamentals in the Voluntary Carbon Market space and shifting buyer preferences for certain credit types based on annual retirements data.

This decision does not impact any of the underlying VCM assessments. Details of our full suite of carbon credit assessments can be found here.
