Since individuals and businesses bear virtually no cost for emitting greenhouse gases in the absence of public policy, and thus have no incentive to reduce these emissions, the government has a strong case for climate change policy. US policymakers may choose among three general approaches to drive more climate-friendly economic activity: (1) subsidise businesses and individuals to invest in and use lower-emitting goods and services; (2) mandate businesses and individuals to change their behaviour regarding technology choice and emissions; or (3) price the greenhouse gas externality, so that decisions take account of this external cost.
