California emissions question

[ROBGoldie@aol.com]

I may possibly be moving out to california within the next 6 months, and am
planning to purchase an A4 1.8T.  I have noticed that the sticker lists
California, Massachussetts and New York emissions for no charge.  Do all 3
states have the same requirements, or is there a difference between New York
emissions and California emissions? I remember reading somewhere that New
York adopted California's emissions standards...
