PARIS -- The sovereign wealth funds of major oil-producing countries have agreed upon a common roadmap to encourage investments toward a greener economy.

The six funds from Norway, United Arab Emirates, Saudi Arabia, Qatar, Kuwait and New Zealand released a joint framework Friday to encourage investors to take climate-related risks into consideration when investing. They also want to improve businesses' transparency on their strategies toward establishing low-carbon economic growth.

The funds hope to send a signal to impact the international financial system. Altogether, they are worth $3 trillion. Norway's sovereign wealth fund, the world's largest of its kind, is worth $1 trillion alone.

The document is to be formally presented during a meeting in Paris of the heads of the funds with French President Emmanuel Macron and Norwegian Prime Minister Erna Solberg.

State-owned sovereign wealth funds are designed to invest their countries' public money for the long term. In an apparent paradox, except for New Zealand, the five others are based on fossil fuels.

The coordinator of the working group of the six sovereign funds, Lawrence Yanovitch, said these countries "see a great commercial interest along the way, because they are saying that they think low-carbon economy is the future."

He stressed all the Gulf countries as well as Norway are already preparing their own economies to a transition toward renewable energies. He said they realize the effects of climate change, such as rising sea levels and more extreme weather.

The move comes six months after a climate summit in Paris in which world leaders, investment funds and energy magnates promised to devote new money and technology to slow global warming. The summit was a reaction to U.S. President Donald Trump's rejection of the landmark 2015 Paris climate accord.

According to the framework, the funds "seek to promote better informed decisions, thereby contributing to a smooth transition to a more low-emissions economy."

Non-binding recommendations notably aim at fostering shared methodologies and indicators related to climate change and identifying "climate-related risks and opportunities."
