Houston Street Exchange

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 Winnipeg Commodity Exchange (WCE), founded in 1887, was Canada's primary agricultural futures exchange, serving as the world's leading market for canola futures and other Canadian crops including oats, flaxseed, and domestic feed wheat. In 2007, WCE was acquired by Intercontinental Exchange (ICE) and renamed ICE Futures Canada in 2008. Canola futures, the exchange's flagship contract, continue to be one of the most actively traded agricultural derivatives globally under ICE.

The Brazilian Mercantile and Futures Exchange (BM&F) was one of the world's largest derivatives exchanges, founded in São Paulo in 1983. In 2008, BM&F merged with the São Paulo Stock Exchange (Bovespa) to form BM&FBOVESPA. In 2017, it merged again with CETIP to create B3 (Brasil, Bolsa, Balcão) — now Latin America's largest financial exchange group by market capitalisation. B3 continues to operate commodity derivatives including sugar, arabica coffee, live cattle, ethanol, and gold contracts.

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.
