CORSIA eligibility labels by phase

Which projects carry a CORSIA label on their registry, by registry and phase, from the labels the registries themselves publish (Verra, Gold Standard, ACR, ART TREES, Climate Action Reserve, Global Carbon Council). The unit figures are each labelled project's unretired balance across all its vintages: not a count of CORSIA-eligible units. A label on a project does not make every unit or vintage eligible — the First Phase (2024–2026) takes only units of 2021–2026 vintages that carry the label. Snapshot of 2026-11-13 — figures describe that snapshot, not a live feed.

* These balances are issued units less retired and cancelled units, summed across all vintages of projects with a label. A project-level label does not establish the eligibility of specific units.

Order follows the source export (document-based ratings first, best first, then v2.2 scores, never interleaved) and is not re-computed here. The First Phase label is the registry's own; the number is CarbonMeld's document-based rating, or a v2.2 score marked v2.2, shown only where one exists.
