PARIS: Oil platforms, pipelines, coal power plants and other fossil fuel assets could lose trillions of dollars in the battle against climate change in the coming decades, experts say.

The warning was issued in a 3,000-page report by UN experts who said fossil fuel assets must be retired and replaced with clean energy faster to mitigate financial losses.

Such assets will become “stranded” and worth less than expected because they may never be used since fossil fuel demand must fall in the near future to limit greenhouse gas emissions.

Limiting warming to the aspirational 1.5 degree Celsius target in the Paris Agreement, or the more conservative 2C goal, “will strand fossil-related assets”, said the UN’s Intergovernmental Panel on Climate Change (IPCC) in its latest report on Monday.

“The combined global discounted value of the unburned fossil fuels and stranded fossil fuel infrastructure has been projected to be around 1-4 trillion dollars from 2015 to 2050 to limit global warming to approximately 2C, and it will be higher if global warming is limited to approximately 1.5C,” the IPCC said.

Any move to alleviate the impact of climate change means using less fossil fuel, thus rendering assets obsolete as companies are under pressure to move away from harmful energy production.

The IPCC said that if current oil, gas and coal energy infrastructure were to operate for their designed lifetime — without technology to capture and store carbon — capping global warming at the 1.5C target would be impossible.

It said nations should stop burning coal completely and cut oil and gas use by 60 and 70 percent respectively by 2050 to keep within the Paris deal goals, noting that both solar and wind were now cheaper than fossil fuels in many places.

The idea of “stranded assets” dates back to the 2010s and was put forward by think tank Carbon Tracker.

Companies could be further affected by governments taking decisions such as increasing the price of coal or even banning certain energies. Consumers could also turn to other products like electric vehicles.

Other assets impacted include infrastructure such as drilling platforms, which have become useless quicker than expected. Some fossil fuel reserves will become too costly to exploit due to falling prices.

For the IPCC, coal-related assets are the most vulnerable before 2030, than those that are oil- and gas-related towards mid-century.

The idea of stranded assets, taken up by both environmentalists and investors, has gained popularity and has been used in shareholder meetings of energy companies such as ExxonMobil or TotalEnergies.

The climate issue has in fact become central to some companies, even if it has taken three decades after the IPCC’s creation in 1988.

“It’s really the financial risk that originally created this spark, which took a long time,” said Hugues Chenet, research associate at Polytechnique and the University College London.

That “convinced financial actors there was a problem.” The idea of “stranded assets” — which Chenet prefers to call “obsolete” — has made it possible to pinpoint a “contradiction”.

There is one “path that says we must live without fossil fuels, facing an economy that is rather more geared up to do the opposite”.
