The worlds largest sovereign wealth fund, which manages $1tn (£786bn) of Norways assets, has been given the go ahead for the largest fossil fuel divestment to date by dropping more than $13bn of investments.
Norways parliament on Wednesday voted into law plans for the fund to dump investments in eight coal companies and an estimated 150 oil producers.
The divestment plan means the fund will drop coal investments worth an estimated $6bn, which could include shares in mining giants Anglo-American, Glencore and German energy company RWE.
The fund — officially named the Government Pension Fund Global — which is built on Norways legacy oil earnings, will also move ahead with plans to scrap investments worth $7bn in oil exploration and production companies.
However, Norways state fund will retain stakes in oil companies which are limiting their exposure to fossil fuels by investing in clean energy technologies. These include BP and Shell, but rule out London-listed North Sea companies including Premier Oil and Tullow Oil.
It will also step back from any company which generates more than 10GW of electricity from coal, or mines more 20m tonnes of thermal coal a year.
Alongside the historic breakthrough for fossil fuel divestment the fund will for the first time have a legal mandate to invest directly in renewable energy projects rather than listed energy companies.
The legislation empowers the fund to invest up to $20bn in renewable energy, which will begin with wind and solar projects in developed markets.
Mark Lewis, head of sustainability research at investment bank BNP Paribas said the laws would allow Norway to join the vanguard of giant solar and wind power investors.
The big story in energy economics over the next decade will be the storming of the bastions of fossil fuels by renewable energy sources that are cheaper to build and run, orders of magnitude cleaner, and also much easier and quicker to deploy, he said.
Norways finance ministry estimates that the value of the global renewable energy infrastructure market will grow by almost 50%, to $4.2tn by 2030, driven by a surge in new solar and wind power capacity additions.
The funds decisive blow to fossil fuel companies comes amid growing calls from investors to end their contribution to the climate crisis.
Stephanie Pfeifer, head of the Institutional Investors Group on Climate Change, an alliance of investors with assets worth $26tn, said the funds move out of fossil fuels into renewables sends a clear signal to the rest of the market.
Other investors will take note when a fund built on oil shows the future is in clean energy, she said on behalf of the groups 170 investors.
She said institutions with $8tn in assets have already divested from the coal sector, while investors with $11tn under management are calling for the companies to end coal use by no later than 2030.
Oil companies must align with the climate goals of the Paris Agreement or face increasing investor pressure too, she said.
Norways oil fund has for years warned its government that failing to sever ties with high-carbon companies could squander Norways state pension fund if they rapidly lose value in a lower-carbon world.
The financial risk facing fossil fuel investors has also been raised by Mark Carney, governor of the Bank of England, and François Villeroy de Galhau, the governor of the Banque de France.
The fund has not named which companies it will drop, but is expected to reveal its divestments as part of its official reporting early next year.
