Moving towards a low-carbon economy will require industries to change their production processes, which may leave some assets stranded. This could have a ripple effect on other sectors, causing financial assets to lose value.

Transitioning away from fossil fuels could lead to a cascade of stranded assets throughout the system. To understand the financial impact, a balance sheet approach is needed for analysis and modeling.
