1

Doesn’t Include Tier 3 transitional bins (Bin 85 and Bin 110)

2

Tier and LEV III are certified to 150,000 mi life, not 100-120,000 as in previous programs

3

Starting in 2017, LEV PM standards drop to 0.003g/mi, with 100% certifying by 2021, and drop further starting in 2025

4

ZEVs are handled separately under CARB’s ZEV Program 

5

Prior to Tier 3 and LEVIII, NOx and NMOG had separate standards, but are shown here as combined for easier comparison 

6

Doesn’t include federal NLEV standards which applied MY 1999 to 2003 LDV and LLDT vehicles
