WASHINGTON – A growing number of lawmakers who are deeply involved in the effort to reduce greenhouse gases and global warming are beginning to question “cap-and-trade,” the current hot-button solution to the problem.

The chairwoman of the Senate Energy and Natural Resources Committee’s energy subcommittee, Sen. Maria Cantwell, D-Wash., says she isn’t so sure the cap-and-trade approach favored by the White House, environmental groups and many of her Democratic colleagues is the way to reduce carbon dioxide emissions from coal-fired power plants and other industries. She fears it could lead to the same type of unregulated Wall Street money-making schemes that fueled the recession.

“I have serious concerns about how a cap-and-trade program might allow Wall Street to distort a carbon market for its own profits,” Cantwell said in an interview.

Cantwell and others are leaning toward a system, dubbed cap-and-dividend, that would cap carbon dioxide emissions and require companies to pay for their credits or allowances. The money raised would be distributed to taxpayers, who likely would face higher utility bills as utilities pass along the added costs of curbing greenhouse gases.

“We are looking at ways that would allow consumers to get something back,” she said.

Congress returns from its spring recess this week with energy and climate change near the top of its legislative agenda.

The House Energy Committee, with 59 members who come from every part of the country and represent all political persuasions, is expected to consider a climate change bill in the next month or so.

Cantwell is one in a growing number of lawmakers who are tinkering with the cap-and-trade approach, including Reps. Chris Van Hollen, D-Md., the chairman of the Democratic Congressional Campaign Committee; Jim McDermott, D-Seattle; and Lloyd Doggett, D-Texas. Other Democrats have proposed an outright tax on carbon dioxide emissions, which Republicans were quick to criticize.

Cantwell has experience in these issues. She helped blow the whistle on Enron and other companies that manipulated electricity markets. She’s railed against natural gas and oil companies that she thinks have maneuvered to drive up prices and reap record profits. She thinks the agencies that might regulate the carbon-trading markets, the Federal Energy Regulatory Commission or the Commodities Futures Credit Commission, are toothless.

The Europeans already have created a cap-and-trade market for carbon dioxide emissions. Credits are being bundled by financial institutions such as Credit Suisse and sold to investors in much the same manner as mortgage-backed securities and other exotic financial products whose collapse helped lead to the global financial crisis, Cantwell said.

“We all know the problems with these derivative markets,” Cantwell said.

One recent report warned that trading in carbon credits and derivatives could grow so quickly that it would create a “carbon bubble” that could burst and create another major global financial meltdown.

“Today speculators do the majority of carbon trading, and they will continue to dominate as carbon-trading markets grow,” said the report from the environmental group Friends of the Earth.

The report said that without proper regulation, the markets soon could be offering “subprime carbon” investments or “junk carbon” offerings.

PLANS COMPARED

There are no standard definitions of cap-and-trade or cap-and-dividend, but both plans are aimed at reducing greenhouse gas emission and getting a handle on global warming. Here’s a quick rundown on the two:

CAP-AND-TRADE

It’s a market-based approach that already is being used in Europe. It’s helped reduce by up to 60 percent emissions of sulfur dioxide, a key ingredient of acid rain, in the U.S.

The government would set an aggressive cap, or maximum limit, on emissions of carbon dioxide that would tighten over the years. Each source of carbon dioxide emissions, such as a coal-burning power plant or other industry, would be given an “allowance,” or credit, that would cap its emissions. The allowances can be bought and sold.

Exchanges that sell carbon credits already exist. Companies that exceed their caps would have to install pollution-control equipment or find other efficiencies. Or they could buy credits from companies that were below their emissions cap.

CAP-AND-DIVIDEND

It’s a relatively new approach that would eliminate the trading of emissions credits. The idea is for the government to cap carbon dioxide emissions. Companies that emit carbon dioxide would have to buy emissions allowances or permits.

The money the government raises by selling the allowances could be rebated to taxpayers in the form of dividends. Utility rates would rise because of the limits, and the dividends would help ratepayers absorb the added costs. But the increased utility rates would be uneven across the country, and there could be fairness issues in distributing the dividends.

There are all kinds of variations, but proponents say cap-and-dividend would lessen the chance of market manipulation and put money back in taxpayers’ pockets.
