Is the impact of carbon emision dependent on the location on the earth?
The climate impacts of CO2 are not constrained to the location they are emitted, but rather the whole globe will feel the effects.  CO2 is a long-lived molecule that takes 100+ years to convert or deposit.  The troposphere, though, only takes months to mix.  There are longer times for mixing between the north/south hemispheres, (e.g. over a year), but it is still short relative to the lifetime of CO2 in the atmosphere.  Globally, you can expect about a 2% variance of CO2 distributions in the well-mixed troposphere.

Here is a recent paper on CO2 distribution from M. Diallo et al.: Global distribution of CO2 in the upper troposphere–stratosphere.  The image below (Fig 6a) shows CO2 distribution for different months in color while the isolines are for potential temperature.
