As a test case, CIty A has decided to pursue regulatory approaches to controlling CO2 in B town, where CO2 emissions primarily come from local electricity generation. There are three power plants in B， and each has submitted their estimated abatement costs for CO2.

Plant 1: Gas Plant releasing 2,400,000 tons of CO2/year
Abatement Approach Tons Removed/Year Cost per Ton
Carbon Sequestation 30,000 \$20
Heat Rate Improvement 1,200,000 \$50
Efficiency Improve ment 95,000 \$70
Increase in lower emitting capacity 2,500 \$190

Plant 2: Gas Plant releasing 90,000 tons of CO2/year
Abatement Approach Tons Removed/year Cost Per Ton
Efficiency Improvement 18,000 \$35
Carbon Sequestrain 12,000 \$45
Fuel switching/construction of wind Capacity 40,000 \$130

Plant 3: Coal Plant releasing 2,740,000 tons of CO2/year
Abatement Approach Tons Removed/Year Cost Per Ton
Carbon Sequestration 26,000 \$30
Efficiency Improvements 70,000 \$60
Fuel Switching 190,000 \$85
Waste Heat Recovery 540,000 \$140

A wants to reduce CO2 emissions by 1,569,000 tons per year (approximately a 30% reduction). They are looking at alternative approaches to achieving this goal, and are interested in comparing the costs of command-and-control to the least-cost solution to achieving this abatement level.

a) Command-and-control: Each plant must reduce their annual CO2 emissions by 30%. Please complete the following table.
Plant1 Plant2 Plant3 Total
Eliminated Emissions(tons)
Remaining emissions (tons)
Total cost of abatement

b) Least-Cost solution: What is the least cost at which the 30% abatement level could be achieved? Complete the following table to indicate how much each plant would abate and the costs of this abatement using least-cost methods.

c) What policies might you recommend to arrive at the least-cost solution? What are some of the pros and cons of each?
