Permits and Marginal Abatement Cost (MAC): Calculating Emissions Reduction Strategies
How can we determine the number of permits and their prices under an ambient permit system?
The Marginal Abatement Cost (MAC) is the cost incurred by a firm to reduce pollution emissions. In this case, we have two sources of pollution (1) and (2), each with their respective MAC values. The MAC for source (1) is given as 0.4Q1, where Q1 represents the amount of abatement by the first firm. Similarly, the MAC for source (2) is given as 0.6Q2, where Q2 represents the amount of abatement by the second firm.
Let's calculate the number of permits and their prices based on the given information:
Calculating Permits and Prices Under an Ambient Permit System
a) If an ambient permit system were established, we need to determine how many permits would be issued and at what price they would prevail. The ambient standard is 24ppm, and without any control, each source would emit 40 units of emissions.
To meet the ambient standard, the total emissions from both sources should be reduced to 24 units (40 - 24 = 16 units). Since each permit allows for the emission of 1 unit of pollution, we would issue 16 permits.
To calculate the price, we need to consider the MAC values and the transfer coefficients. The transfer coefficient for source (1) is A1 = 1.5, and for source (2) is A2 = 1.
The price of a permit is determined by the highest MAC value divided by the corresponding transfer coefficient. In this case, the highest MAC value is 0.6Q2 (from source 2) divided by its transfer coefficient of 1. Therefore, the price of each permit would be 0.6Q2.
b) If the permits were auctioned off, each source would need to spend an amount equal to the number of permits multiplied by the price of each permit. Since we have 16 permits and the price is 0.6Q2, each source would spend 9.6Q2 on permits.
c) If each source was initially given free of charge half of the permits, they would receive 8 permits each. Each source would then need to purchase the remaining 8 permits, resulting in a cost of 4.8Q2 per source.
Understanding Emissions Reduction Strategies
In the context of emissions reduction, the calculation of permits and prices under an ambient permit system plays a crucial role in incentivizing firms to reduce pollution. By analyzing the Marginal Abatement Cost (MAC) and considering the transfer coefficients, we can determine the most efficient strategies for emission control.
The calculation of permits ensures that the total emissions from multiple sources do not exceed the ambient standard, thereby promoting environmental sustainability. Moreover, pricing permits based on MAC values and transfer coefficients encourages firms to invest in pollution abatement technologies and practices.
Overall, understanding permits and MAC values enables policymakers and firms to develop effective emissions reduction policies that balance environmental protection and economic considerations.
