Among those whose names have been generating buzz in the run-up to Friday's announcement are media watchdogs Reporters Without Borders, the Committee to Protect Journalists (CPJ) or the International Fact-Checking Network, as well as anti-corruption champion Transparency International.

"We are very happy. This is what we hoped for," Henrik Siverts, chief physician at the accident and emergency ward at a hospital in Oslo, told newspaper Aftenposten. 

Among the new rules introduced were a curfew on scooter use at night, the introduction of designated drop-off zones, and the decision to cut the number of scooters significantly.
