The decision affects around 90 companies, which have been added to KLP's exclusion list alongside industries it previously divested from, including tobacco firms, certain weapons makers and those involved in the mining or usage of coal.

Explaining its decision, KLP said it did not want to make money from products that can harm people who are vulnerable to addictions, adding that there are better ways in which pension savings can make a sustainable contribution to society.

The company, which has around $80 billion in assets under management, also consulted customers and owners before taking this decision, it added.

Among the excluded companies were casino group Wynn Resorts, online gambling firm Betsson, spirits and beer maker Diageo and brewers such as Carlsberg and Heineken.

KLP will also continue to refrain from owning stocks and bonds of pornography companies, it added.
