What I could find about the latest standards does not seem to support your claim. But maybe I'm looking at wrong numbers or misinterpreting them, so I wouldn't mind looking at your own sources if you have them.
EURO 6d standards for diesel passenger cars [1]:
- CO: 0.5 g/km
- NOx: 0.080 g/km
- PM: 0.0045 g/km
California LEV standards for passenger cars <50K miles/5 years [2]. (Not the same as EPA, but I assume California is more strict):

California LEV standards for passenger cars <50K miles/5 years [2]. (Not the same as EPA, but I assume California is more strict):
- CO: 3.4 g/mi = 2.1 g/km
- NOx: 0.2 g/mi = 0.12 g/km
- PM: 0.08 g/mi = 0.05 g/km
