Mars and the Moon are quite different in their composition. Mars has a lot of chemistry useful in creating a more hospitable atmosphere, it just needs
to be chemically unbound from the rock and soil.
In addition to being "gravitationally challenged" the Moon lacks the chemistry to create those greenhouse gases.
Another interesting scenario credited to Robert Zubrin, is an accelerated program wherein rocket motors are strapped onto small and medium sized
asteroids and slammed into Mars at high velocities. The kinetic impacts would release more of the chemistry into the atmosphere than even hundreds of
nukes, and set up a greenhouse effect much quicker than "pollution factories" ever could.
Purely theoretical. But it would sure be more spectacular than watching smokestacks belch for a few hundred years or so.
