What are the economic and societal costs and benefits of mitigating air pollution?
Why You Should Care
Air pollution was one of the major environmental issues at the first Earth Day in 1970, and the next two decades saw significant laws and regulations. Those regulations have decreased air-pollution levels across the country while allowing the economy, population, and fossil fuel use to all increase.
Today, those air-pollution levels are still creating environmental impacts from acid deposition, to human health impacts, to climate change. Even though air-pollution levels are lower than they were in 1970, they need to go lower still. Those changes will involve shifting away from fossil fuels and toward renewable-energy sources, and this will require a significant economic and social shift in order to succeed. Renewable sources are more expensive, but the gap is far less if we include the external costs of cleaning up the damage, paying for health impacts, and mitigating climate change.
These changes will have up-front costs to transition away from one technology and toward new technologies: This makes the transition unpopular among both industry and consumers (who may pay more for similar products). However, failing to transition costs us prolonged damage to ecosystems, increased death rates from asthma and indoor air pollution, and greater chances of climate change causing serious ecosystem shifts.

Short-Answer Questions
The Clean Air Act of 1970 and its subsequent amendments have lead to a 65% decrease in acid precipitation since 1976. But the increased regulation and scrubber technology to reduce SO2 release from power plants have focused regulation on the problem to transboundary air pollution. For example, New York State is significantly impacted by SO2 release from Ohio and Pennsylvania’s power plants. Also, New York State’s particulate matter releases impact New Jersey, Connecticut, and Massachusetts. The Clean Air Act was never intended to adjudicate a legal dispute about "who released what and where?"
In 2005, the EPA instituted the Clean Air Interstate Rule (CAIR) to monitor and track particular emissions from each state that was east of the Mississippi River (these 28 states contain both the majority of the pollution and the majority of the population of the United States). Each state would have a cap on the amount of each pollutant that could be released and was given the freedom to decide how to divide up that emission cap among its industries and residents.

2) Without a market for the excess emissions to be traded, it cannot be a cap-and-trade system. Command and control dictates levels for the state and requires the sources to meet those levels. In this setup, CAIR is closer to that system than a cap and trade.
3) Across the board, standards make it difficult for all industries to meet the new standard at the same time; some will require more time or more money to implement changes. Setting up a cap-and-trade market allows industries that are below their quota through lower use or increased technology to sell their extra emissions at a profit. This also allows the states to meet their goals faster (as long as the industries have an incentive to meet it).
