During the COVID pandemic, international air traffic came to a near halt and airlines had hardly any revenue. Several companies went bankrupt or had to downsize. Norwegian Air underwent restructuring and legal reorganization, which made it no longer able to meet obligations such as purchasing and transferring EU ETS emission allowances.
In January 2021, Norwegian and its subsidiaries began to reduce their fleet by returning various aircraft, including Boeing 787s for long-haul flights, to their respective lessors. On January 14, 2021, Norwegian announced the end of all long-haul services to focus on a smaller European route network.
Norwegian disputed the obligation to purchase emission allowances and offered the Norwegian government a share transaction equivalent to the excused ETS amount. The Norwegian government did not accept this form of settlement and imposed a fine of approximately 35 million euros.
