Many economists favor a carbon tax as a way to discourage CO2 emissions. Suppose such a tax were to be set at $20 per ton (907kg) of carbon emissions as (CO2). Consider a 50-MW, 35% efficient power plant that uses coal with a carbon intensity of 24gC/MJ.

a. How much per year would this power plant pay in carbon tax?

b. Suppose a tree plantation sequesters (removes from the atmosphere and stores in biomass) 20,000kg of carbon dioxide per year per acre over the next 40 years the trees are growing (after which time the forest is mature and no further accumulation occurs). What area of forest would have to be planted to offset the power plant’s emissions over the next 40 years (roughly the lifetime of the power plant)?

c. What is the maximum the power plant owners would be willing to pay for this forest per acre? (do not use discounting)

Suppose the State of Oregon is successful in establishing a new tax on carbon emissions. Burning coal to generate electricity is known to generate substantial carbon emissions, and so the State’s new policy adds a tax on the market for coal-fired electricity. a) Use a supply-and-demand diagram to show what happens to the quantity of coal-fired electricity and the price that consumers pay for coal-fired electricity. b) Wind power is a substitute for coal-fired electricity. Suppose that wind power production...

Carbon dioxide (CO2) emissions are widely believed to be a driver of global climate change. In this problem set you will use cross-section data to test what drives countries’ “carbon footprints,” that is, their CO2 emissions. Is it population, or is income the bigger culprit? The data set “CO2 by country 2010 sh S17” contains data on a sample of countries’ CO2 emissions, in kilotons; population, in millions; and gross national income (GNI), in millions of US dollars, for the...

1. Suppose that Climate Change is caused the emissions of carbon dioxide and methane gases. Suppose further that the United Nations proposes a policy to combat these emissions to reduce the impact of Climate Change. This policy proposes that each country in the world reduces their carbon dioxide and methane emissions by 50% over the next two years (i.e., each country should cut their emissions by half). The United Nations suggests that countries could tax polluters to get them to...
