{{Use dmy dates|date=April 2022}}

The European Climate Exchange (ECX) managed the product development and marketing for ECX Carbon Financial Instruments (ECX CFIs), listed and admitted for trading on the ICE Futures Europe electronic platform. For a time it was a subsidiary of the Chicago Climate Exchange, but eventually became a sister company. Both companies as well as IFEX were owned by Climate Exchange Plc, a holding company listed on the London Stock Exchange's Alternative Investment Market, founded by Richard Sandor.{{cite web |url=http://www.climateexchangeplc.com/investor-relations/recommended-cash-acquisition-by-aether-ios-limited-of-climate-exchange-plc |url-status=dead |archive-url=https://web.archive.org/web/20100505174716/http://www.climateexchangeplc.com/investor-relations/recommended-cash-acquisition-by-aether-ios-limited-of-climate-exchange-plc |archive-date=2010-05-05 |title=Climate Exchange Plc}}{{cite web |url=http://www.climateexchangeplc.com/ |title=Home |website=climateexchangeplc.com}} A chief executive was Patrick Birley, son of archaeologist Robin Birley.[https://web.archive.org/web/20110612040440/http://business.timesonline.co.uk/tol/business/markets/europe/article2697778.ece Traders with a permit to save the planet][http://www.birley.org/jbirleyd/d152.htm#P152 Patrick Burley at www.birley.org] {{webarchive |url=https://web.archive.org/web/20050223163931/http://www.birley.org/jbirleyd/d152.htm#P152 |date=February 23, 2005 }} While products were listed on the London Stock Exchange, the sales and marketing team was initially based in Amsterdam, the Netherlands, under its first CEO, Peter Koster,{{cite web |url=https://www.bloomberg.com/research/stocks/private/person.asp?personId=22803668&privcapId=39666402 |title = Stocks - Bloomberg|website = Bloomberg News| date=28 October 2023 }} before moving to London in 2007. Climate Exchange Plc was bought in April 2010 by Intercontinental Exchange.

ECX provided a pan-European platform for carbon emissions trading, with its futures contract based on the underlying EU Allowances (EUAs) and Certified Emissions Allowances (CERs), which had attracted over 80% of the exchange-traded volume in the European market. ECX contracted (EUA and CER Futures, options and spot contracts) were standardised exchange-traded products. LCH.Clearnet was the designated clearing house prior to 2008; later, all trades were cleared by ICE Clear Europe.

More than 100 businesses, including companies such as Barclays, BP, Newedge, E. ON UK, Endesa, Fortis, Goldman Sachs, Morgan Stanley and Shell, signed up for membership to trade ECX products. Using a process called 'order routing, ' several hundred clients could access the market via banks and brokers without having to be members.

ECX was bought out by its partner ICE Futures Europe in 2008.
