Reply to comment by WeylandsWings in New review finds that rocket emissions in the upper atmosphere can affect the ozone layer but are not regulated — Global annual launches grew from 90 to 190 in the past 5 years, and an upsurge in rocket launches may potentially undo decades of work to save the ozone layer by marketrent

As you have shown the percentages can you also give us a link to the mass of the fuel reflected in these percentages. I think that would help in quantifying the amount of admission being dumped into the different layers of our atmosphere.

Each launch is roughly the equivalent of a 747's worth of fuel (kerosene or methane).

About 650 kg/s for the inputs according to Wikipedia. 510 kg/s of LOX and 140 kg/s of CH4 for a Raptor engine.

But it really depends on the engine in question and the throttle level.
