Yes, relatively speaking, each launch contributes a "large" amount, but it is completely irrelevant when looking at the overall picture. There are ~100 launches a year, compared with 7 billion miles driven by automobiles per year [1] for example.

I don't have a source handy, but I remember hearing that each launch is the equivalent of the annual output of 2 passenger vehicles. So all rockets launches worldwide = 200 drivers.
