What morons put their heads together and insert Greenland on the green list, perhaps inspired by the name?
And then not have Iceland and the Faroes on the list, about the only two european countries where for the last 6 weeks you get tested on arrival, result sent by sms afer a few hours, follow-up test after 4 or 5 days included in the service and both countries virtually virus free with no restrictions in place.
The only way to travel to/from Greenland via a clean certified 'green' path is by using the St Brendan boat route.
