Proof-pack-equipped tier on ACX listings.
AirCarbon Exchange (ACX) is a key venue where per-tonne evidentiary disclosure becomes a priced attribute. A listing-level quality tier, a futures-contract specification, or a settlement-layer integration each produce the same market-design effect: buyers and sellers can discover price on quality. Proof-pack-equipped credits acquire a liquidity and pricing premium; unequipped credits trade at a discount. The market bifurcates — which is what a functioning commodity market is supposed to do.
