All of these calculators are using figures calculated on actual CO2 emissions divided by the population as the base and then by putting in actual spend/usage/lifestyle choices the figure is raised or lowered to reflect more accurately your personal/household score.  How these adjustments are made will mean that you are unlikely to have the same score by imputing the same figures into each calculator, but they should not be wildly different.  The main thing is to choose which one appeals to you the most and stick to that one.  By repeating your carbon calculations every 6 months you should be able to track your progress towards zero carbon.
