Platts proposes to discontinue several voluntary carbon market price assessments, Dec. 1

Platts, part of S&P Global Commodity Insights, proposes to discontinue three voluntary carbon market price assessments, effective Dec 1, 2025.

Platts proposes to discontinue Platts CNC, as well its Household Devices Energy Efficiency Project Differential, and the Renewable Energy Latin America Differential, owing to changing dynamics in the voluntary carbon market :

• Platts CNC reflects the most competitively priced nature-based carbon credits, including nature-based standardized contracts. The proposed discontinuation reflects declining liquidity for standardized products and a preference for credits from nature-based solutions with recognized performance and market acceptance . These credits are more typically traded in the OTC market, and market activity is captured within Platts separate Nature-Based Avoidance and Natural Carbon Capture price assessments.

• Platts Household Devices Energy Efficiency Project Differential captures the discount or premium for carbon credits generated by Energy Efficiency projects such as, but not limited to, LED Lightbulb projects and improved building efficiency projects, versus Platts Household Devices Current Year price assessment. The proposed discontinuation reflects the limited circulation of Energy Efficiency credits in the market.

• Platts Renewable Energy Latin America Differential reflects the discount or premium of Renewable Energy projects located in Latin America compared to the Platts Renewable Energy price assessment. This proposed discontinuation reflects the decline in issuances of Renewable Energy carbon credits in Latin America and end-buyers' preferences for credits from other project types. Platts also recognizes that these credits usually trade as an outright value, rather than as a differential to credits from other regions.

A summary of the assessments proposed for discontinuation are as follows:

The proposed discontinuation also includes the above assessments ' currency conversions and monthly averages.

The assessments appear in CMA2001, ETA2001, CMA2002, ETA2002, CMA2003, ETA2003, CMA2004, ETA2004, CMA2005, ETA2005, CMA2006, ETA2006, CMA2007, ETA2007, CMA2008, ETA2008, CMA2009, ETA2009, CMA2011, ETA2011, and in Carbon Markets Daily.
