Findings Congress finds that— (1) aviation accounts for 3 percent of the total greenhouse gas emissions of the United States; (2) aviation is 1 of the fastest growing sources of anthropogenic greenhouse gas emissions; (3) greenhouse gas emissions resulting from aviation are projected to triple by 2050; (4) flying first class has been estimated to have up to 7 times the carbon footprint of flying in economy class; (5) flying first class on a single domestic round-trip flight can generate more greenhouse gas emissions than the average greenhouse gas emissions from a year of driving; (6) private jets are, on average— (A) 10 times more carbon intensive than commercial airliners; and (B) 50 times more carbon intensive than trains; (7) operators of private jets benefit from public airport infrastructure, but fail to pay their fair share for the maintenance, upkeep, and administration of that infrastructure
