A Cost is generated
But not reflected in market
Market Outcomes are wrong (inefficient)

$42 (in $2007) per ton of CO2 emitted in 2020 (central tendency – wide variation)
What’s in the number? Agriculture Health Ecosystem services Property damages

Demand Side Policies
Can policies reduce and redirect energy demand to less carbon-intensive energy sources?
• For consumers who use heating and cooling, transportation, etc.?
• For businesses that use energy as an input?
• For public sector energy use (federal, state, local governments.)?

Supply Side Policies
Lower the amount of energy produced from carbon fuels
Provide incentives to change how energy is generated
![Page 18: Great Swamp Watershed AssociationWeb].pdfGreat Swamp Watershed Association ... The Challenge of Global Warming: ... Interagency Working Group on Social Cost of Carbon,](https://reader033.fdocuments.net/reader033/viewer/2022051600/5aa49ffe7f8b9a7c1a8c6039/html5/thumbnails/18.jpg)
Supply Side Policy: Technology
Incentives for new/clean Energy Technology
• Solar• Wind• Biofuels• Nuclear (?)• Hydroelectric
• INNOVATION!

Key Issues in Alternative Fuels
Are the technologies scalable?
What are the costs of new energy sources?
Are the costs competitive?

Policy Examples: Regulation
Technology Standards:Require specific technologies
Performance Standards:Producers meet them however they choose
Ambient Standards:Target for ambient levels of carbon, temp., etc.

Economic Implications of Tax/Subsidy Policies
Who pays subsidies?
Do subsidies (ever) end?
Can we put a price on carbon?
Prices and costs matter!

Sweden $150 (US) / ton CO2
British Columbia $30 (CAN) / ton CO2
Australia $23 (AUS) / ton CO2
Norway $15 - $62 / ton CO2

Cap and Trade
![Page 31: Great Swamp Watershed AssociationWeb].pdfGreat Swamp Watershed Association ... The Challenge of Global Warming: ... Interagency Working Group on Social Cost of Carbon,](https://reader033.fdocuments.net/reader033/viewer/2022051600/5aa49ffe7f8b9a7c1a8c6039/html5/thumbnails/31.jpg)
Advantages of Cap and Trade
The CAP creates scarcity and can be tightened
The carbon price creates incentives to reduce emissions
Emitters can trade among themselves
Lowers the overall cost of CO2 reduction
![Page 32: Great Swamp Watershed AssociationWeb].pdfGreat Swamp Watershed Association ... The Challenge of Global Warming: ... Interagency Working Group on Social Cost of Carbon,](https://reader033.fdocuments.net/reader033/viewer/2022051600/5aa49ffe7f8b9a7c1a8c6039/html5/thumbnails/32.jpg)
Cap and Trade Examples
California – GHG Cap and Trade Program (2012!)
U.S. - SO2 Emissions (Acid Rain Reduction) (1990)
European Union – GHG Emissions Trading Scheme
New Zealand – Emissions Trading Scheme

Mitigation vs. Adaptation: Example
Sea Level Rise/Storm Surge (one of many consequences of global warming)Is it more cost effective to:Reduce emissions to prevent it?Or to develop ways to deal with the consequences
after it has happened? E.g., defense, strategic retreat
Example: What to do for the Jersey Shore?
