Bezos' New Shepard is fueled by liquid Hydrogen and Oxygen, it only emits water, no CO2, no soot. Branson's SpaceShipTwo does release carbon, it burns approximately 3 tons of HTPB (basically rubber) per flight. The CO2 emissions from such a flight are roughly equivalent to 3500 miles of driving per paying passenger. That $250,000 ticket leads to as much CO2 entering the atmosphere as $60 of coal. At current rates, the cost to sequester that much carbon is $210, approximately 0.8% of the ticket price. If every single billionaire on Earth each took a flight on SpaceShipTwo, it would release as much CO2 as 13 flights over the North Atlantic, of which there are normally 2500 per day. Odds are the environmental cost of getting those billionaires to Mojave would dwarf the cost of their rocket flights.
