All CCOs issued to date: 220.94 million

Compliance credits awaiting issuance: 14.13 million

CA and General Market Commentary:

  • On May 27th, ARB released the results of its quarterly allowance auction. Current vintage allowances cleared at $18.80, a substantial premium to the $17.71 auction reserve price.  The bid-to-cover ratio was 1.48, a strong result compared to auctions in 2020.
  • Issuances of CCOs continued to be slow in May. The ROC backlog increased by nearly 3 million.  Relatively low issuances of new CCOs continue to constrain the offsets available to entities as they look to fulfill their obligations at the 3-year compliance deadline on November 1st.
