[QUOTE="mfb, post: 6832140, member: 405866"] There is nothing political in my response. "The main carbon footprint will be the fuel" is a purely technical response, and it answers your concern about manufacturing. It's negligible compared to the fuel used, and I also explained why: Because the vehicle gets used often. I don't see the relevance for spaceflight, but [url=https://www.acea.auto/figure/co2-emissions-from-car-production-in-eu/]building a car in the EU produces around 0.6 tonnes of CO2 emissions[/url]. You match that if your car burns around 200-300 liters of fuel, something cars typically exceed by a big factor in their lifetime. If Starship has the same dry mass to CO2 emission ratio as cars then its production will be around 200 tonnes of CO2. It's tiny compared to the CO2 produced from the propellant even after a single flight. Add reuse and you can imagine how negligible the fraction becomes. Can you stop driving this thread off-topic with wrong claims please? [/QUOTE]
