One rocket launch produces up to 300 tons of carbon dioxide into the upper atmosphere where it can remain for years.
Don’t think that’s true for Blue Origin though as it uses Hydrogen & Oxygen mix so only* produces water vapour – although this forms clouds in the upper atmosphere and contributes to climate change/global warming.
Where as Bransons ‘Rocket plane’ uses solid fuel which it just like burning a bunch of old tyres in terms of pollution etc…..
The 300 tons is more like the standard rocket launches of NASA/Space-X/Russia/China etc.
*There are a few other biproducts of combustion but not huge amounts.
