A computer-implemented trading platform, system, and method are provided for facilitating the trading and accounting for health quality offsets. So-called “health quality credits” related to emissions of ‘potentially avoidable complications’ (PACs) or ‘potentially avoidable mortality’ (PAMs). Emissions trading or “cap-and-trade” is an administrative approach used to control emissions that degrade public-goods assets by providing economic incentives for achieving and sustaining economically significant reductions in the emissions of pollutants that impair public goods such as clean air or health. In one embodiment, a method of accounting for health quality offsets established in one or more offset markets includes registering a health quality offset to an owner thereof; assigning a unique identifier to the health quality offset; crediting a client account with the health quality offset; receiving notification of a trade between a buyer and a seller, if the seller has an amount of health quality offsets sufficient for the trade, adjusting buyer and seller accounts with corresponding credits and debits; otherwise, providing a notification of insufficient health quality offsets to carry out the trade.
