Steven F. Leer, the chairman and CEO of Arch Coal in St. Louis, one of the major suppliers of coal to the utility industry, believes we need to significantly step up the search for a solution to that problem. "The only way you can be serious about stabilizing CO2 concentrations is that the United States and Europe invest in carbon sequestration technology, carbon capture technology and get on with it," says Leer. "We need 10 to 12 years and a meaningful investment of a couple billion dollars a year in these technologies, but we can get there."

Meantime, Michael Morris, chairman and chief executive of American Electric Power, said in a Wall Street Journal article that the cost of sharply reducing the 2.5 billion tons of CO2 emitted by utilities each year - one-third of all such emissions - will be unprecedented. "I think power prices could go up 50 percent, maybe more."

With price disruptions of that magnitude barreling down on the utility industry, you can almost taste the risk in the air. That is opportunity for some. The New York Mercantile Exchange is preparing to help utilities and all industry deal with the risks they will face if Congress, as expected, eventually puts in place a carbon dioxide cap and trade emissions regime. James E. Newsome, NYMEX president and chief executive officer, says that he believes a futures contract tied to CO2 emissions restrictions is just 18 months off. It will fast become the largest commodity market, eclipsing even oil futures.

"It'll be huge," says Newsome. "It can dwarf oil. Any industry that is creating emissions that need to be neutralized will have the ability to do so through an exchange contract."

Some estimates put the size of the financial services business now emerging to help deal with emissions issues at $30 billion, on its way to $1 trillion. London is emerging as the global center of carbon finance, given the city's window on Europe's early efforts to curb greenhouse gas emissions. While Europe's cap-and-trade system has been beset with problems, policymakers there are determined to iron out the wrinkles.

But, if all of those efforts are to succeed and particularly after 2012 when the Kyoto Protocol expires, the Americans and the Australians must get involved, says Anthony White, a principal in the Canada-based Climate Change Capital. Both have rejected Kyoto because of its failure to address emissions in the rapidly industrializing parts of the Third World. Ultimately, he says, "We need a carbon price people can invest against."
