i think the important thing to consider is that not EVERYTHING has to emit no carbon… it’s perfectly acceptable (IMO) to make air travel carbon neutral by eg carbon capture, etc… sometimes it’s just not efficient to either carry around carbon neutral but not dense fuel, or capture and carry your waste with you
it’s shit that carbon offset programs have been hijacked :(
This seems to be a key point ppl miss. There is still quiet a big question if cdr and storage can be net negative...for example one place we want to store co2 is in saline basins, but this will require disposal and treatment of the brines removed from the basin...which might emit might end up emmiting as much co2 as ends up being stored in the saline basin. There is a paper on this issue....
