The European Climate Exchange (ECX) managed the product development and marketing for ECX Carbon Financial Instruments, 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. A chief executive was Patrick Birley, son of archaeologist Robin Birley. 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, before moving to London in 2007. Climate Exchange Plc was bought in April 2010 by Intercontinental Exchange.
