International Petroleum Exchange
The International Petroleum Exchange, now ICE Futures (since 2005-04-7), based in London, was one of the world's largest energy futures and options exchanges. Its flagship commodity, Brent Crude was a world benchmark for oil prices, but the exchange also handled futures contracts and options on fuel oil, natural gas, electricity (baseload and peakload), coal contracts and, as of 22 April 2005, carbon emission allowances with the European Climate Exchange (ECX).
