Sen. Dianne Feinstein offers plenty of tips on how California households can combat global warming, such as carpooling and running only a full dishwasher.
But one bit of information Feinstein declines to share is the number of times that she flew last year on her husband's Gulfstream jet, which burns much more fuel per passenger-mile than commercial airliners.
Gov. Arnold Schwarzenegger also has asked constituents to do their part to conserve energy -- including cutting summertime power consumption -- even though he takes to the skies on leased executive jets.
Aides say there is nothing contradictory between the pro-green pronouncements and the flying habits of the Democratic senator and Republican governor.
Some environmentalists aren't so sure.
"There appears to be a discrepancy between calling on people to make personal reductions and using a private jet that exacerbates the problem," Clean Air Watch President Frank O'Donnell said.
Flying on a Gulfstream rather than an airliner is like driving a sport utility vehicle instead of riding a bus, O'Donnell and others say.
A single cross-country round trip on a Gulfstream IV, or GIV, the model owned by Feinstein's husband, churns out about 83,000 to 90,000 pounds of carbon dioxide, experts say. By contrast, on a per capita basis, the average American produces 50,000 pounds from all activities in an entire year.
Nonetheless, Feinstein and Schwarzenegger intend to continue their noncommercial flying ways because their jobs demand a flexibility the airlines can't match, spokesmen say.
Schwarzenegger's office said he and a jet-leasing company are establishing a "carbon offset" program for the governor and fellow customers, retroactive to Jan. 1. Carbon offsets are bought from organizations that plant trees and support renewable energy enterprises, among other measures, to offset greenhouse gases produced by the buyers.
"This is big news," Schwarzenegger spokesman Bill Maile said of the governor's undertaking with NetJets, the leasing firm.
Feinstein, however, got the jump on Schwarzenegger. She began buying carbon offsets last year to partially cover the travel on the GIV, and will purchase enough offsets this year to compensate for all the trips, spokesman Scott Gerber said.
He added that Feinstein took "numerous" commercial flights in 2006, but flew mostly on the GIV. He balked at disclosing the tally of her Gulfstream journeys.
"We're not going to get into specifics," he said.
Noncommercial aircraft and other carbon-related indulgences have caused politicians considerable turbulence recently.
A conservative group has condemned Al Gore for racking up an average monthly electricity bill of $1,200 at his Nashville mansion last year while championing the anti-global warming cause. A Gore spokeswoman said the former vice president invests in renewable energy to offset his electricity use.
As part of an ethics push, the House and Senate are toughening restrictions on lawmakers who fly private jets, though exceptions for members and spouses who own planes are under consideration.
Earlier this month, Republicans accused House Speaker Nancy Pelosi of requesting a large military jet to fly her and family members between the capital and her San Francisco district.
Security protocols grant Pelosi occasional military flights because she is second in line to the presidency. Her office said she had only inquired about an aircraft with enough fuel capacity to make the trip nonstop, and would fly commercial if necessary.
Pelosi flew on private jets seven times in 2006, her spokesman said. "She made every effort to travel commercially whenever possible," Drew Hammill said.
Sen. Barbara Boxer says she took four trips on private aircraft last year, one with multiple stops over 2 1/2 days.
"If you can take a commercial plane to get where you need to go at the time you need to be there, you should do it," she said in an e-mail. "If not, you have to look at alternatives such as trains, fuel-efficient vehicles, buses, and in some cases, private planes."
For that last option, Feinstein reimburses her husband, Richard Blum, for use of the jet, Gerber said. Blum bought the GIV for about $23 million in 1999. The reimbursements are based on a first-class commercial fare, with more than 90% of the money coming from Feinstein's personal funds and the rest from campaign coffers, the spokesman said. Last year, the reimbursements to Blum totaled about $73,000, he said.
But a GIV's operating expenses are much higher than a first-class booking. A round-trip Los Angeles-Washington flight on the Gulfstream burns about 4,500 to 5,000 gallons of fuel at a cost of roughly $20,000, depending on local pump prices, said Jeff Beck, a veteran corporate pilot. And that doesn't include pilot fees, maintenance and parking bills.
"It's the least environmental thing that politicians can do," Beck said. He said Gulfstreams devour so much fossil fuel per passenger that "it's like they're throwing dinosaur bones out of the tailpipe."
A coast-to-coast, first-class ticket on a major airline goes for about $1,200 to $2,500, round trip, according to a sampling of three airlines' prices Tuesday.
A Boeing 767-200 airliner burns about 1,550 gallons an hour -- three times as much as a GIV. But the larger plane typically can seat about 180 passengers, as opposed to a GIV's 12 to 14.
Eric Carlson, executive director of Carbonfund.org, a nonprofit that sells offsets, said it would charge $229 to cover the emissions from the GIV round trip.
Schwarzenegger flies a variety of leased jets, which cost his campaign $733,000 during the three months ending last September. Maile said the governor digs into his own pockets for some flights.
He also said Schwarzenegger has converted one of his Hummers to biodiesel fuel, and plans to install solar panels on his house. His other three Hummers remain gas hogs.
For her part, Feinstein drives a hybrid Lexus sport utility vehicle when she is home in San Francisco, Gerber said. But she drives a Lincoln Town Car in Washington.
Not that the eco-crowd is eager to criticize Feinstein and Schwarzenegger, who are generally viewed as key supporters of the growing movement to curb emissions.
Representatives of some environmental groups either would not comment on the two politicians' penchant for private jets, or suggested that allowances could be made in their circumstances.
"Given the exigencies of the campaign trail, if not the demands of governing of a large state, it may not be realistic to expect elective officials to fly commercial all the time," said Jon Coifman, spokesman for the Natural Resources Defense Council.
But O'Donnell, of Clean Air Watch, invoked a loftier ideal:
"It is fair to hope that our political leaders will lead by example."
