What are the environmental concerns that arises when we talk about space tourism?

Space tourism is a new term for us. But the race has already been started. Recently commercial space tourism race was started by Virgin Group founder Sir Richard Branson and Ex-CEO of Amazon, Jeff Bezos. .

Basically their demonstration was to offer the people to reach outer space, feel zero gravity and take a glimpse of Earth from space.

But you might have known a rocket emits 100 times more carbon dioxide for a passenger than a flight. So, if this space tourism race started then imagine the amount of green house gas this industry will emit!
