The Saturn V used for the Apollo missions burned 203,000 gallons of RP-1 (basically kerosene) in its first stage. At 820 kg/m^3, that’s 630 metric tons of fuel. Liquid hydrocarbons tend to be close to CxH2x, or about 85% carbon by mass, so that’s 536 metric tons of carbon, which yields 1965 tons CO2 when burned, or 655 TonCO2/astronaut. Obviously that’s not personal consumption, but it is a lot of carbon in the atmosphere.
The emerging space tourism industry, on the other hand, is primarily personal consumption. I’d love to take the trip, but I’d be a little put off if the consequences of seeing the big blue marble from above were to make a major contribution to climate change. So, what are the consequences?
