UPDATE:Ex-Ameritrade Chief Named CEO Of CME's Green Exchange

Former Ameritrade chief Thomas Lewis was named Tuesday to head Green Exchange Holdings LLC, an emissions-focused market backed by CME Group Inc (CME).

The appointment comes as the nascent New York market seeks regulatory approval from the U.S. Commodity Futures Trading Commission and the U.K. Financial Services Authority ahead of a broader rollout.

It also marked another step for CME into a developing asset class that could become one of the largest derivatives markets, as governments move to mandate trading of greenhouse gas emissions to curb pollution.

"We see this as a global platform for liquidity for all environmental commodities, across all jurisdictions," Lewis said in an interview with Dow Jones Newswires.

The Green Exchange came onto the scene in December 2007, backed by a consortium of Wall Street banks, the New York Mercantile Exchange and the emissions brokerage Evolution Markets Inc., where Lewis served as a director.

Chicago-based CME, the world's biggest futures exchange operator, acquired its stake in the Green Exchange in 2008 via the purchase of Nymex.

Lewis said Tuesday that his top priority was to begin building an executive team, adding positions focused on product development, compliance and Washington affairs.

The Green Exchange chief is also in the hunt for additional equity partners in the Green Exchange, which he said has roused interest among brokers, banks and hedge funds.

The Green Exchange's slate of products, currently listed for trading and clearing by Nymex, cover futures and options on European Union Allowances, carbon allowances tied to the Regional Greenhouse Gas Initiative, and other greenhouse gas markets.

Despite support from banks like Credit Suisse (CS), JP Morgan Chase & Co. (JPM) and Goldman Sachs Group Inc. (GS), trading activity on the Green Exchange platform has yet to take off, partially due to the uncertainty created by the CME-Nymex merger.

However, CME Group senior management has expressed support for the venture in recent months and introduced new emissions- and carbon-focused products at Nymex, which are eventually slated to transfer to the Green Exchange.

Last week brought an announcement of new serial options contracts on E.U. allowances and Certified Emission Reductions.

In both U.S. and European carbon markets, the Green Exchange will play catch-up to Climate Exchange PLC (CLE.LN), which operates the dominant carbon markets on both sides of the Atlantic.

CME rival IntercontinentalExchange Inc. (ICE) in June took a minority stake in Climate Exchange, which already used ICE's trading platform.

Lewis said the Green Exchange's backers give it an edge, however.

Existing Nymex energy markets in crude oil, natural gas and coal will provide cross-margining opportunities that will draw in participants, Lewis said, while banks and brokers have committed to provide liquidity to the market and devise new products.

"As part of this deal, they have a strong interest in creating contracts that will give [participants] the ability to hedge and manage their portfolios across these products," he said.

Besides Ameritrade, Lewis also served as chief executive of Automated Power Exchange Inc. and was an executive in residence at John Hopkins University, where he focused on environmental finance.
