Combustion emissions from rocket engines affect the global atmosphere.
Historically, these impacts have been seen as small and so have escaped regulatory attention.

Geoengineering is controversial, and there is no formal policy regarding its deployment…
“A global ban on “… injection of particles into the stratosphere…”28 could present a problem for space launch, which currently injects approximately 10 gigagrams of BC and alumina particles into the stratosphere each year.”

The critical things coming out of a liquid fuel rocket as it blasts off is:
(big white cloud from the water cooling system at the launch pad) H20
CARBON MONOXIDE which will quickly bond into carbon dioxide.
NITROGEN NITROGEN NITROGEN
many other TRACE GASES that are “insignificant”.
RED = EPA considers pollutants
= OZONE depleting substances GREEN
= GREENHOUSE GASES OR RADIATIVE FORCING BLUE
types of rocket fuel
RP-1 often mixed with liquid Oxygen- highly refined jet fuel – or kerosene
solid rocket fuel
SOLID ROCKET BOOSTERS (SRB) are the most polluting in first stage of launch
SRB made from :
Salt of Perchloric Acids
Aluminum or Magnesium Powder
