Not an omission, Greenland is an autonomous territory in the Kingdom of Denmark. Denmark is listed.

Greenland is an autonomous territory in the Kingdom of Denmark that, at least as rendered on my screen, is missing from the map entirely.

I don’t know where you are looking, but Greenland is on the map on page 8 and colored gray to represent “not included”
