Platts proposes to launch additional California Carbon Offset assessment, update name, specifications for existing CCO Current Month assessment, June 1
Platts, a part of S&P Global Energy, proposes to launch an additional price assessment for California Carbon Offsets (CCOs) with Direct Environmental Benefits in the State (DEBS), effective June 1, 2026.
Platts recognize s the relevance of differentiating between CCO s with the DEBS attribution attached and its importance in compliance obligations. Compliance entities may use up to 6 % of compliance offset credits to fulfill their compliance obligations for emission s from 2026-2030. Half of the offset credit use limit must have the DEBS attribution.
Given this, Platts proposes to launch an assessment for CCOs with DEBS an assessment with the following specifications:
| Assessment Name | Platts CCO DEBS |
| Volume: | 5,000 mt- 50,000 mtCO2e |
| Credit type : | Credits with Direct Environmental Benefits in State (DEBS) and z ero invalidation |

| Delivery: | Spot market 3-5 days forward |
| Frequency: | Daily |
| Unit of Measurement: | $/mtCO2e |

Simultaneously, Platts proposes to update the volume for its existing CCO Current Month Current Year Vintage assessment from the original specifications of 1,000-10,000 mtCO2e to 5,000- 50,000 mtCO2e. This change would reflect more typical volumes traded in the spot market.
The updated specifications for the assessment would be as follows:
| Existing Specifications | Proposed Specifications, effective June 1 | |
