Introduction
In this book, we argue that the United States has the opportunity to improve its air pollution regulatory regime. It can do so by reforming its current regulations—which are a mix of command-and-control policies and cap-and-trade programs—to be more economically efficient. We provide the theoretical apparatus to demonstrate that efficient regulations should be preferred over current regulations, and we argue that we now have the data and methods to make the design of an efficient regulatory regime possible. We also show how these data can be used to begin to develop a system of environmental accounts that measure the damages associated with pollution in the United States. Efficient regulations would be the next step in the evolution of air pollution regulation in the United States, which has passed through several stages over the last six decades.
Before World War II, there was little in the way of binding environmental regulation in the United States. After World War II, state and local governments began to react to deteriorating environmental conditions by controlling emissions. The federal government’s role in this area was initiated by the passage of the Clean Air Act (CAA) in 1963. The first federal regulations to control emissions were in the 1965 amendments to the CAA that established performance standards for automobile emissions. The CAA amendments of 1967 and 1969 established national emission standards for stationary sources and criteria for ambient air quality standards (USEPA 2008). The CAA amendments required the use of specific control technologies by polluters. These amendments employed technology standards.
In 1970, further amendments to the CAA created the U.S. Environmental Protection Agency (USEPA) and developed the National Ambient Air Quality Standards, which set maximum allowable concentrations of certain air pollutants harmful to human health for every county in the United States. Furthermore, the USEPA was granted broad authority to set emission standards across a range of existing pollution sources and to mandate more stringent standards for new sources. The 1970 CAA resulted in notable reductions in air pollution. Figure I-1 shows historic emission levels for three principal air pollutants: sulfur dioxide (SO 2 ), volatile organic compounds (VOCs), and nitrogen oxides (NO x ). This figure shows that the first appreciable emission reductions did not occur until the passage of the 1970 CAA; emissions of SO 2 , NO x , and VOCs all peaked in 1970 and declined precipitously thereafter.
Although a series of important amendments to the CAA were passed in 1977, our brief history of air pollution policy in the United States moves next to the 1990 amendments to the CAA. The 1990 amendments highlight the use of cost-effective market-based policies, which stand in stark contrast to the traditional reliance on command-and-control instruments embodied in earlier policies. The 1990 amendments established the first cost-effective regulations through the enactment of a cap-and-trade program. Under the Acid Rain Program, which was established by Title IV of the 1990 amendments, fossil fuel–powered electric generating plants were issued tradable permits for SO 2 emissions. These permits allowed firms to generate emissions of SO 2 provided that they held an allowance for each ton emitted. If any firm anticipated not having enough allowances, it could purchase additional allowances from another firm. Conversely, if a firm abated enough emissions so that it had excess permits, it was allowed to sell the permits to other firms. Recognizing that allowances are a valuable asset, regulated firms had an incentive to invest in abatement technology in order to sell their allowances to other participants in the program. This cap-and-trade program is cost-effective because each polluter equates the cost of abating an additional ton to the current permit price. The cap-and-trade program for SO 2 is estimated to have reduced abatement costs for utilities by as much as $1 billion annually. Later in the 1990s a similar cap-and-trade program for NO x emissions was instituted in the eastern United States to control ozone levels.
Regulation under the CAA has achieved marked reductions in pollution discharges, but these
