A decade ago, it was very conventional for asset managers to have exposure to the oil and gas sector as part of a diversified portfolio. Calls for them to divest from carbon assets because climate policy could render fossil fuel reserves unburnable mostly fell on deaf ears. But now the oil & gas sector has turned in a decade of underperformance, vaporizing tens of billions of dollars and becoming the worst-performing sector in the world. Now banks, asset managers, and even oil operators have now joined the ranks of those worrying aloud about the increasing risk of stranded assets. Now, the warnings about stranded assets are converging with calls for companies and investors to apply ESG filters to their activities, and investors are demanding divestment from carbon-heavy assets. One think-tank saw all this coming: Carbon Tracker. In fact, they put the concept of stranded fossil fuel assets on the map over a decade ago. In this episode we speak with its founder, Mark Campanale, about what investors have learned from the experience of the past decade, what they still need to do going forward, and some of the more interesting efforts that are under way to encourage divestment from carbon and reorient capital toward energy transition solutions.
