Ranked country leverage, company transition exposure, and outreach priorities computed from the Trellison EIA medallion + corporate-disclosure data.
Across the 14 largest-emitting countries (covering ~26,190 MtCO2 / ~75% of global emissions), the average ETS coverage is 36%. That means roughly 18,275 MtCO2 — the majority of the surveyed emissions envelope — carries no explicit carbon price and no compulsory verification requirement.
This is the market-design opportunity that proof-pack disclosure addresses: a per-tonne evidentiary record is the instrument that lets an unpriced tonne become trustable, without requiring the full political machinery of a new carbon price.
Each country scored on 4 factors (0-100 each). Composite score is the sum. Higher score = bigger proof-pack adoption leverage. Regulated = ETS coverage × carbon price × published emissions. Disclosure = gap between published and EIA-measured CO2. Strategic = fossil-electricity share + crude-oil production. Transition = near-term regulatory urgency.

Transition exposure = scope-impact × (1 + national fossil share) × (1 + cost intensity). Higher score = lower-friction proof-pack adopter.

No country in the 14 surveyed achieved Tier A or Tier B composite scores. Indonesia alone reached Tier C (168.8). The policy framework globally is not yet tight enough to produce an A-tier mandatory-adoption environment anywhere. This empirically validates the "voluntary-first, regulator-aligned" approach to proof-pack adoption — proof packs should be available BEFORE regulators mandate them.
Equinor already pays $2.2B/year in Norwegian CO2 tax + EU ETS costs — the highest cost-intensity in the surveyed cohort ($48.9/Mt Scope 1+2). For an operator already paying that much, proof-pack-equivalent disclosure is almost free on the margin — the marginal complexity is low, the marginal differentiation is high. Equinor is also the Northern Lights CCS operator, where proof-pack-backed removal credits would command a premium. Recommended first-adopter outreach.
Shell scored top on transition exposure (44.0) driven by 1,115 MtCO2 Scope 3 — a liability the size of Germany's entire national emissions footprint. A Shell proof-pack commitment would be the most consequential single corporate signal in the CDR market, and would likely trigger a peer cascade among the European majors (BP $600M, TotalEnergies $925M both paying similar ETS costs).
Empirical re-ranking of outreach targets shows the top 4 slots all go to compliance-market regulators: EU DG CLIMA, CARB, RGGI, UK DESNZ. These regulators directly shape which tonnes carry which evidentiary requirements for market access. A CEQ memorandum or a congressional hearing lands with second-order leverage; a CARB rulemaking lands with first-order leverage. Sequence accordingly.
Active carbon prices span Indonesia ~$2 to Germany/EU ~$75 — a 37× spread. A proof-pack-equipped tonne produces the same integrity signal at any price, but the value of the signal is highest where the price is highest: in the EU ETS where compliance already costs European majors €800M–€2.2B per operator per year. That is where proof-pack-equipped premium tiers will first bifurcate the market.
