Depends on how many. Flying airplanes is around 1-2% of our total CO2 footprint. Of course, for an individual, doing 1 intercontinental flight with a full plane is equivalent to months if not a year of driving a car to work every day, but in total, not many people fly.
Depending on the efficiency of the rocket and the reduced number of people doing this, the numbers shouldn't be that much higher.
