The term
"carbon bubble" refers to the possibility that the market value of fossil fuel companies, such as oil, gas, and coal, may dramatically decline in the future. This is because to limit climate change, we need to reduce our carbon emissions, which would mean using less of these fossil fuels. If countries and industries transition to cleaner energy sources, the demand for fossil fuels could drop, causing the value of these companies to "burst," similar to a bubble.
