Reading the discussion section of the full study, cardboard reduces gas permeability but not by a big enough amount to significantly affect the total amount of gases in the soil. They also say the effects of reduced gas permeability would be reduced in field conditions where you would have planting holes and gaps in the mulch. So, not much to worry about in my opinion.
