Emissions are going to go down when starship is made as well.
Starship uses a methane + oxygen fuel which burns cleaner, and can be produced with just water and CO2 making it carbon neutral.
I don't think every flight will be neutral immediately, or what % will be consistently once its scaled up, but it'll be better.
But 1 carbon neutral flight sending up hundreds of satellites will bring it down quickly. They could even save the carbon neutral flights for themselves for PR purposes.
This sounds like a set up for if Trump wins.
Trump: Im the world's savior, I prevented World War 3 with Russia by giving them back their illegally stolen Alaska. No president has ever done anything so great for the world!
