Allowances are the permits entities purchase to emit in CA. Entities can substitute offsets for up to 4% of their total (the minimum price at which entities can purchase allowances in 2027 increases by 5% annually plus CPI-U).
(Bid/Ask Prices are taken from multiple broker quotes for the period ended May 31, 2026. The 2026 CA Floor Price is the regulatory minimum auction price for allowances. The 2027 estimate is based on regulatory rules and ClimeCo’s assumption of inflation in 2026 as measured by the CPI-U index. Green numbers indicate positive changes during the month, red numbers indicate negative changes during the month, and black numbers are unchanged.)

CA and General Market Commentary:
- The CA Air Resources Board approved amendments to the Cap-and-Invest program at its meeting on May 29. This approval clears the way for CA and QC to consider linkage with WA, possibly as early as January 1, 2027.
- Quebec released a draft proposal regarding updates to its program. The proposal includes reducing the number of offsets allowed from 8% to 6%.
- Issuances of CCOs in May totaled 119,375. We are watching the issuance trends as compared to the same period in previous years to gauge the future available supply of DEBs and Non-DEBs offsets. Issuance volumes so far this year are historically low:
| .Year | Total Issuances YTD |
