Guess we're not a terribly "green" bunch here but i thought I'd have a look at my XT's CO2 emissions.
Plugged in OBD adapter using bluetooth and Torque Pro App and here's what I got.
Intake temps were nice and low too around 24-26c, went upto 64c sat in traffic !!
Obviously this info is from the cars's
ECU....... I haven't had it professionally tested.
Very interesting to note my old ford is "greener" than the new Series 2 Commodore

I'll be converting to E85 soon to see how it improves.
Chuck up some results from your motors if you can
