Stranded Fossil Fuel Assets and the Carbon Bubble

In following the topic of economic bubbles, it’s worthwhile looking into what’s called the “Carbon Bubble.” The idea behind the Carbon Bubble has to do with stranded assets — assets that are on the books of a company but that can never be exploited for profit. This is potentially the case with companies that are in the business of extracting and exploiting fossil fuels — coal, oil, and gas. The problem is that such fuels are causing climate change and are thus becoming increasingly subject to regulation. It’s possible that a significant volume of fossil fuels now on the books of coal and oil companies will never come to the surface and will eventually have to be written off at massive loss.

This problem was well explained recently by Joel Makower at — see “Exxon, stranded assets and the new math.” Makower’s piece was prompted by¬†an announcement that ExxonMobil, the U.S.’s largest energy company, will be releasing the first Carbon Asset Risk report by any such company. A press release from Arjuna Capital says that the forthcoming report “will provide investors with greater transparency into how ExxonMobil plans for a future where market forces and climate regulation makes at least some portion of its carbon reserves unburnable.”
