Carbon bubble

A carbon bubble is when a certain industry's value is based on something that scientists say is bad for the environment. For example, when a company creates something that causes pollution or damages the planet, the value of that company's stock may increase or be high. But when scientists figure out that those things harm the planet, people don't want the company's product or services anymore. This means the company's stock value will decrease, like a bubble bursting. So the “carbon bubble” is when these companies’ stock values shrink or “pop” because of what they do to the environment.
