You'd have consumed about 0.45 l/km of kerosene per flight km per passenger. Calculation based upon [0]. That means you'd need to offset CO² emissions of about 1.11 kg CO² per flight km [1] for yourself.

Wow that's great, thank you for finding these and doing those calculations. I'm glad to read it's one of the more fuel efficient aircrafts.

Flightaware puts the actual distance at 760km, so it'd be ~844kg of CO².

I found this great guide by the David Suzuki Foundation which assesses different carbon offset vendors with a few different measures:

Pages 42-49 go into the different criteria, Page 50 is the table scoring them all.

I decided to go with https://carbonzero.ca, it was $19.89CAD for 0.88t. Thank you for your help :)
