1. Front of Room

2. Pollution Control • Catalyst • What is nitrogen fixation? What is it done by? • In what three ways do animals return nitrogen to the environment? • Clearly, pollution is an enormous problem. Based on what we have learned so far, what do YOU think is the best way to significantly reduce the amount of pollution produced in the United States? Write in complete sentences! Don’t talk during the Catalyst!

3. Objectives By the end of today, all SWBAT… • Describe two methods of pollution control: command and control, and cap and trade • Describe the advantages and disadvantages of each method of pollution control

4. Agenda • Pollution Control Intro reading • Key point 1 • Venn Diagram • How does cap and trade really work? • Copenhagen Summit Intro • Stop and Jot • Develop your own policy

5. Background Vocab: • Regulate = to control by rules/laws • Protocol = system of rules

6. Intro to Pollution Regulation • Read the two success stories and answer the reflection questions • Read carefully • Be thoughtful in your responses

7. CFC Success Story: Montreal Protocol

8. Acid Rain Success Story: Emissions Trading

9. Pollution Control Regulation Key Point #1: There are two methods to regulate pollution • Command and Control • Cap and Trade

11. Complete the Venn Diagram using the phrases on your classwork sheet Cap and Trade Command and Control

12. How does Cap and Trade Really Work? If a company pollutes LESS than the laws allows, they can make money by selling their pollution “credits” to other companies If a company pollutes too much and can’t pay for “credit,” they either have to fix their factory, put out less, or pay a fine.

13. Scenario 1 • Cap: 200 million tons of air pollution • Each factory is allowed 100 million tons of sulfur dioxide pollution • Credits can be sold for $1 per ton of pollution (ex: 10 tons costs $10) • Factory 1: Emits 30 million tons of sulfur. What should factory 1 do? Why? • Factory 2: Emits 150 million tons of pollution. It would cost $200 million to fix factory. What should factory 2 do? Why?

14. Scenario 2 • Cap: 800 million tons of air pollution • Each factory is allowed 100 million tons of sulfur dioxide pollution • Credits can be sold for $1 per ton of pollution (ex: 10 tons costs $10) • Factory 3: Emits 250 million tons of pollution. The cost of repairing the factory is $25 million. What should factory 1 do? Why? • Factory 4: Emits 150 million tons of pollution. What should factory 4 do? Why?

15. Key Point #2: Currently, the international community is creating a law to regulate CO2 levels

16. Current CO2 Regulation: Copenhagen Summit (December 2009) • Goal: Limit global temperatures rising no more than 2 °C (3.6 °F) above pre-industrial levels. • Not legally binding • “Recognized” by 193 nations, but not supported by all 193. • Promises to deliver $30 billion of aid to developing nations over the next three years • Help poor countries cope with the impacts of climate change

17. Stop and Jot: Do you think that the Copenhagan Summit can successfully regulate global CO2 levels? Explain your reasoning. Stop and Jot • Use your knowledge about the Copenhagan Summit and why CFC and SO2 regulation was successful!

18. Classwork Part B • Your assignment is to develop a proposal or amendment to the Copenhagen Summit based on your knowledge of pollution regulation of SO2 and CFCs. Your proposal will be submitted to the Copenhagen Summit Council at their next meeting. • Write your proposal on a separate sheet of paper.

19. Exit Question Factories emit 5,000 tons of Pollutant X every day. • Describe how the government could reduce Pollutant X emissions using Command and Control regulation. • Describe how the government could reduce Pollutant X emissions using Cap and Trade regulation.
