Rubicon Carbon, LLC

Named as beneficiary of 647 t CO₂e retired in 46 retirements from 28 projects · 2023-04 → 2026-04

Retirement records as read from the registries on 15 Nov 2026.

Source: the public retirement records of ACR, GS, VCS (beneficiary named by the registry). A retirement beneficiary is not necessarily the direct purchaser of the credits, and only retirements where the registry publishes the beneficiary are counted, so the total can be lower than what the organisation retired. The quality view below is CarbonMeld's assessment of each project — not a rating of the company.

What these tonnes are

  • Projects without a document-based rating45%
  • Projects with a registry status of rejected, withdrawn, terminated, suspended or issuance denied1%
  • Projects carrying the registry's CCP label23%
  • Carbon removal projects1%
  • Projects carrying a CORSIA eligibility label6%

Shares weight each project by the tonnes this organisation retired from it: the denominator is all retired tonnes and the categories overlap — a project can carry several labels at once. They use today's registry labels and CarbonMeld assessments of the projects, not the vintage-specific certification of the retired units, and not those at the time of retirement. The unassessed share is not a quality verdict: it names projects without a current CarbonMeld assessment.
