Well of course it does

National Geographic says global warming is the greatest threat to human health; it also flies billionaires around the world in its private jet

National Geographic raises funds by flying deep-pocketed travelers around the world on its "specially outfitted" Boeing 757 jet, which features "comfortable VIP-style leather seating," "plush, sleek interior design," a private chef, and a "dedicated luggage handler." The trips, most of which cost roughly $100,000, allow millionaires and billionaires to "fly in exceptional comfort" as they visit "far-flung destinations" and encounter "legendary wildlife"—including the same coral reefs National Geographic says in its pages are dying.

Travelers on one of the 24-day "expeditions" fly nearly 30,000 miles. Planes, on average, produce 53.3 pounds of carbon dioxide per air mile, meaning the trip's flights would emit more than 1.5 million pounds of carbon dioxide. The average American's yearly carbon footprint is just 32,000 pounds, meaning the flights in just 24 days generate a carbon footprint equivalent to that of nearly 47 Americans in an entire year.
