What is a good exhaust emision result?

My Scenic 2003, 1.4 has just passed its MOT; and I was just wondering how to judge my exhaust emission results.

Its done 115,000 miles, how does it compare with other engines?

CO: = 0.134

HC: = 41 PPM

Lambda: = 1.011

-----------

Engine speed = 749 RPM

CO: = 101%
