The Chicago Climate Exchange (CCX) was North America's first and only voluntary, legally binding greenhouse gas emission reduction and trading system. Founded in 2003 by economist Richard Sandor, CCX allowed member companies to make binding commitments to reduce carbon emissions and trade Carbon Financial Instruments (CFIs). Acquired by ICE (Intercontinental Exchange) in 2010, CCX ceased operations the same year after voluntary carbon credit prices collapsed following the failure of US cap-and-trade legislation.

The Chicago Mercantile Exchange (CME) is one of the world's most influential financial exchanges, founded in 1898 as the Chicago Butter and Egg Board and renamed CME in 1919. Headquartered in Chicago and part of CME Group, CME offers futures and options across meats, currencies, Eurodollar interest rates, equity index products, and a range of financial instruments, providing global risk management solutions to participants in over 150 countries.

HedgeStreet Exchange was a CFTC-regulated US derivatives exchange founded in 2004, offering small-denomination binary contracts (starting at $10) on economic events including crude oil prices, gold, natural gas, and macroeconomic indicators. Designed to democratise derivatives access for retail traders, HedgeStreet was one of the first exchanges to offer CFTC-regulated retail binary options on commodity prices. In 2008, the exchange was acquired and eventually rebranded as Cantor Exchange (part of Cantor Fitzgerald), which subsequently ceased operations.

Flett Exchange was a New Jersey-based electronic exchange for environmental commodity credits, established around 2004. Flett specialised in US environmental market instruments including NOx (nitrogen oxide) allowances under the EPA SIP Call, SO2 (sulphur dioxide) allowances under the Acid Rain Program, Regional Greenhouse Gas Initiative (RGGI) carbon allowances, and Renewable Energy Certificates (RECs). The exchange served power generators, utilities, and compliance buyers navigating the complex US state and federal cap-and-trade regulatory frameworks for air emissions.
