The ride up emitted 82.5T of CO2 per person.
A single Bitcoin transaction emits 1T of CO2.
An average American home emits 5T of CO2 per year.
One round-trip flight from New York to London emits 1T of CO2 per person, and seats about 300 people.
So for perspective, it produces about as much CO2 to fly 4 people to space as a 777 from New York to London round-trip. Now there are 233 daily flights from New York to London - or 85,000 per year. And that's just New York to London.
There have been 18 Blue Origin launches.
It's a campfire. A pricy luxury that a few folks take advantage of. Should everyone do it? No. Can everyone do it? No. A carbon tax will sort all this out.
But saying we shouldn't address the 85,000 flights from NYC to LHR per year because Bezos blasted off a few times is a really poor way of framing the conversation.
- monocasa 5y agoI question your numbers because New Shepard doesn't use carbon based fuel at all. It's replacement, New Glenn, is the problem here.
- arcticbull 5y agoI see, I was using this [1] although you are of course right that it's a liquid hydrogen/liquid oxygen rocket. While it's not carbon free to obtain those, but the numbers are probably quite a bit lower for New Shepard.
