GradeBuddy is best used as a supplement to your own notes, not as a substitute.Stakeholders- Person or group that has a financial or political interest in climate change policy- Each group wants to influence government policy on the regulations of greenhouse gas emissionso Energy Industry group focus on cost of action If we take immediate political action to reduce GHG emissions:- Economy will suffer greatly- Fossil Fuel energy is cheap and economy needs it- Millions of $ needed to transition to renewable energy sources Renewable energy is not advanced or reliable enough- Sun doesn’t always shine Fear of cost of action- Climate regulation will be costly- Alternate energies are too expensive - Will damage the economyo Environmental stakeholders: cost of inaction (doing nothing) If we do not take immediate political action to reduce GHG emissions: - Cost of disasters such as storms/floods/fires- Droughts, heat-waves caused economic losses (crop failures) - People will need to migrate (unexpectedly)  Fear of cost of inaction- Without regulation, climate impacts will be costly- Alternative energies creates new jobs- Will damage the economyGuest Ivan RudikThe social cost of carbon- The SCC is the cost to society, in $, of one ton of CO2 emissions- CO2 impacts society through many channels (increases in temperature)o Changes in agricultural outputo Sea level riseo Health impactso Ecosystem services, non-market amenities- Number of studies analyzing warming in these sectors, but additional steps are needed to get the cost of CO2- Why is it important to put a $ value on emissions?o Need to value cost correctly in order to know cost of electricity Coal-fired and gas fired electricity is inexpensive- Does not account for cost to society of the emissions produced as by-product To figure out what cheapest energy sources are, need to know the cost of emissionso Determine the true costs and benefits of environmental policies Cost of setting carbon-focused policy are costs of having carbon-intensive firms meet whatever policy regulators set Need to know benefits of emissions we will be avoiding through these policies todetermineo Set optimal carbon policy- Does this matter?o The US government established an interagency working group specifically to value cost of GHG emissionso Cost of carbon is not included in price virtually every goodo Basic Econ tells us that the world will be better off if the cost of CO2 is included in the price of goods so people account for the costs they impose on society can be achieved simply by tax on CO2- How do we determine SCC?o Integrated Assessment models (IAMs) Models of the climate system linked to models of economic systemo Per MWh, coal generates approximately one ton of CO2 (among other pollutants) One MWh of coal truly costs somewhere between 5$-40$/MWh more, making itmore expensive than
