This is inaccurate because if you take the high end of the Falcon 9 per-launch emissions estimates discussed in this thread (about 28k metric tons equivalent of CO2) and divide by the payload size (about 17 metric tons) then each gram of matter lifted into space would be taking about 1.5 kilograms of CO2-equivalent emissions, which is a small amount instead of an enormous amount.

For 1-gram of material, that's a lot, now that we just shattered 1.5ºC global temperate gain, especially for something pointless.
