If no fee for a pollution permit were charged, how many tonnes of pollutants would be discharged into the atmosphere, assuming a straight-line demand curve? Quantity: tonnes b. Suppose government were to set a fee of $3,000 per pollution permit. How many tonnes of pollutants would now be dumped? What is the total revenue received by government? Quantity: tonnes Total revenue: $ c. Suppose that a new technology allows for a significant reduction in hydrocarbons at a relatively low cost so that the demand for pollution permits in the industrial park drops by 200 tonnes. Assuming that government holds the permit fee at $3,000, how many tonnes of pollutants would now be…
- Scientists at the Global Footprint Network calculate the energycomponent of our ecological footprint by estimating the amountof ecologically productive land and sea required to absorb thecarbon released from fossil fuel combustion. This translates into4.9 ha of the average American’s 7.2-ha ecological footprint.Another way to think about our footprint, however, is to estimatehow much land would be needed to grow biomass with anenergy content equal to that of the fossil fuel we burn.Assume that you are an average American who burns about6.3 metric tons of oil-equivalent in fossil fuels each year andthat average terrestrial net primary productivity (p. 32) can beexpressedas 0.0037 metric tons/ha/year. Calculate how manyhectares of land it would take to supply our fuel use by presentdayphotosynthetic production. Compare the energy component of your ecological footprintcalculated in this way with the 4.9 ha calculated usingthe method of the Global Footprint Network.
