Exchange Tradable Assets
AirCarbon Exchange (ACX) applies traditional commodity exchange architecture to carbon credits. Traditional commodities (e.g.: corn, soybeans and crude oil) trade digital receipts representing commodities held in a warehouse. These warehouses are organized around predefined specifications.
Similarly, we currently securitize carbon credits into tradable carbon asset classes. We organize credits around the markets they serve. Carbon credits held by the exchange are held in a Trust. For every credit deposited into the Trust, a corresponding one digital receipt, as defined below, resides on the Exchange.

Verification Process:
AirCarbon Exchange (ACX) has engaged British Standards Institution (BSI), a pioneer in system certifications and ISO training, to perform Contract & Carbon Credit Verification. The Contract & Carbon Credit Verification Process provides confidence to clients that the reported information and associated characteristics of a carbon credit are a faithful, true and fair account of the carbon credits in question and that they conform to the contract specifications from ACX.
