EU Emissions Trading Scheme (ETS) as an Example of a Pigouvian Policy

Challenges of Implementing Cap-and-Trade Systems

An environmental agency wants to reduce total sulfur dioxide emissions from two power plants to 100 tons per year. It creates a system where each plant is given 50 tradable emission permits, with each permit allowing one ton of emissions. Plant X can reduce its emissions at a cost of $20 per ton, while Plant Y can reduce its emissions at a cost of $100 per ton. Based on the principles of this system, what is the most likely outcome?

Efficiency of Tradable Permit Systems

In a tradable permit system for pollution, once the initial trading of permits is complete and the market price is established, only the firms that have high pollution reduction costs continue to have a financial incentive to invest in cleaner technology.

Match each component or outcome of a tradable permit system for pollution control with its primary role or effect.

In a system where a government sets a limit on total pollution and allows companies to trade permits for emissions, the method used to initially distribute the permits (e.g., giving them away for free versus auctioning them) is the primary factor that determines the final, total amount of pollution.

A government that manages a tradable permit system for industrial pollutants decides to decrease the total number of permits available to firms, effectively lowering the overall pollution limit. Assuming no other changes in the economy or technology, what is the most likely immediate effect on the market for these permits?

A government is implementing a market-based system to reduce a specific pollutant from its industrial sector. Arrange the following key stages and outcomes into the correct logical order, from the initial policy action to the system's ongoing operation.
