In that chart:
HC = Hydrocarbons
CO = Carbon Monoxide
PM = Particulate Matter
NOX = Nitrogen Oxide
So yes, savings in some places (green house gases) and increases in others (cancer causing chemicals).
Now, depending on how they treat the NOX (via a trap like the 2.0L engines, or with the BluTech liquid for larger engines) this can be mitigated, but yes, there is a 10% increase in NOX which would be above the legal CARB limits, which may or may not apply in your state.
