According to my handy text here, "An increase in the concentration of 
carbon dioxide results in an increase in acidity which in turn 
decreases the affinity of oxygen for haemoglobin." (_Biological 
Science - Principles an Patterns of Life_, G. Wilson)

So it seems to be more the change in pH as opposed to the binding of CO2.
