CII og EEXI

open access: yes, 2022
Bacheloroppgaven skal ta for seg hvordan CII og EEXI vil komme til å påvirke befraktere. Med utgangspunkt i dette har det blitt utarbeidet en problemstilling som blir støttet opp av fire forskjellige hypoteser, som hver tar for seg et ulikt område knyttet opp mot den valgte problemstillingen. Anvendt teori er hentet fra rapporter, forskningsartikler og
