Investing the state's revenues from oil and gas production and managed by a unit of Norway's central bank, the fund is one of the world's largest investors, investing its cash across 9,200 companies in 70 countries, among other assets.

"We will now vote against board members if a company has experienced material failures in the oversight, management or disclosure of climate risk," the fund said in its annual report on responsible investments, published on Thursday.

The fund has long engaged on climate change with the companies it invests in.

Its latest move was in September, when it laid out plans to firms to cut their greenhouse gas emissions to zero by 2050, in line with the Paris Agreement and following a mandate from Norway's government.
