WASHINGTON -- House Speaker Nancy Pelosi is leading a large delegation on at least two Air Force jets to Copenhagen for the climate summit -- where participants harshly condemn the use of jet airplanes for the high amounts of CO2 they emit.

"This may be the largest congressional delegation I have ever heard of," said a source at the 89th Air Wing stationed at Andrews Air Force Base of the trip to the UN summit, which is increasingly being criticized as a farce.

But Republicans on Capitol Hill and the 89th Air Wing source said Pelosi actually reserved five planes to carry a delegation that includes as many as 24 Democrats and six Republicans.

"Climate change is a religion for them, so there was no way they were going to miss this," said one top GOP aide. "This is their Hajj."

Rep. Charles Rangel (D-Harlem) was among those planning to go because of his duties as chairman of the House Ways & Means Committee, a staffer told The Post.

"We all know that Charlie Rangel is a big fan of subsidizing his vacation with taxpayer money, but the truly offensive aspect of this is Nancy Pelosi's decision to bring the corrupt Harlem Democrat along for the ride," said Republican spokesman Ken Spain.

The roundtrip cost to Copenhagen and back for the C-32A would cost taxpayers $160,000.

The 737 carries 26 passengers and costs about $7,500 per hour of flight time, bringing the costs of a Copenhagen jaunt to $120,000.
