Your argument does not make sense. Of course fewer people have less influence on the outcome, but that is not an excuse to do less (per person) in the smaller group. India could just split into 2000 states and turn your argument straight around... This is just not how collective obligation works, in the very same way that you absolutely CANT argue with your tax officials that "it doesn't really make a difference whether I pay" (or your village/city if they're small). I just picked America as example because they're arguably the worst of the bunch in Co2/capita (except some rich tiny states like Luxembourg), so good on you for doing better than them (probably). Also feel free to make an argument using different metrics for pollution, but I have strong doubts that you could change the conclusions-- also consider that climate change is precisely that big a problem because it is not quickly reversible at all. Co2 is also a metric where you can get easily comparable numbers and those are already unfavorable even WITHOUT taking into account how much pollution is outsourced by wealthy nations (which is hard to quantify).
