 Norwegian law followed EU legislation and on 1 January 2012 also prohibited battery cages (known as "tradisjonelle bur" or 'traditional cages' in Norwegian), making funished cages (known as "miljøbur" or 'environmental cages' in Norwegian) the minimum legal requirement.Several more industry groups have decided to voluntarily phase out furnished cages as well, such as NorgesGruppen by 2019 and Nortura by 2024, while in April 2017 the Green Party proposed to ban furnished cages throughout the country by 2025.Switzerland banned battery cages from 1 January 1992; it was the first country to impose such a ban.
