In economyChapter market in action Explain two market mechanisms that are used for controlling pollutions as an externality?

Two market mechanisms used for controlling pollution as an externality are cap-and-trade systems and pollution taxes. Cap-and-trade involves setting a maximum allowable level of pollution, distributing emissions permits to firms, and allowing them to trade these permits in a market, incentivizing reductions in emissions. Pollution taxes impose a fee on emissions, encouraging firms to reduce their pollution output to minimize costs. Both mechanisms utilize market forces to internalize the environmental costs of pollution, promoting more sustainable practices.
