Consider an oil company extracting oil from the Oil Sands in Northern Alberta. The production process generates greenhouse-gas emissions. At the socially optimal level of oil extraction,
◦ the level of emissions will be zero.
◦ the social marginal cost of the oil extraction will be equal to its social marginal benefit.
◦ the social marginal cost of the oil extraction will exceed its social marginal benefit.
◦ the marginal cost of the emissions will be more than the social marginal benefit derived from the extracted oil.
◦ the marginal cost of the emissions will be equal to the social marginal benefit derived from the extracted oil.
