Decline of Air Pollution, Rising Abatement Costs

March 9, 2015
Manufacturers face the law of diminishing returns as Washington pursues new environmental measures.
U.S. manufacturers have been highly successful in reducing pollution over the past two decades, yet their costs to shrink their environmental footprint continue to grow. They're being affected by the law of marginal returns and each new pollution regulation that EPA devises will be increasingly more costly to implement. Two recent studies help bear this out. In one, the MAPI Foundation compared pollution abatement costs among manufacturers around the world and found that U.S. manufacturers have the highest bill -- roughly double that of Japan, three times as much as Germany, and about six times as much as Canada and Korea. MAPI Foundation Chief Economist Dan Meckstroth's analysis, which examined air pollution, greenhouse gases, waste disposal, and wastewater treatment, showed that U.S. manufacturers spend roughly $25 billion annually in pollution abatement costs, the highest for any country in the world. This amounts to about 1.2% of manufacturing value-added, comparable to what manufacturers experience in most other advanced economies, where strict regulations have also increased business costs. (Canada's manufacturers pay the most as a percentage of manufacturing GDP, at 2.2%, primarily because of the nation's preponderance of waste- and wastewater-intensive industries, such as pulp and paper, steel, and petroleum refining. Mexico's manufacturers pay the least, at 0.8%.)

When looking at air pollution abatement -- including the reduction of nitrogen oxides (NOx), sulfur dioxide (SO2) and particulate matter (PM) -- U.S. manufacturers spend $5.3 billion annually, more than the other eight countries in the study combined. As a percentage of manufacturing value-added, this amounts to 0.27%, which is higher than every other country except Canada. Another study demonstrates U.S. manufacturers' resounding success in reducing their air pollution. Georgetown economist Arik Levinson shows that between 1990 and 2008, U.S. factory air emissions fell by two-thirds, even as the real value of manufacturing output grew by 35%. Dr. Levinson observed that advances in production techniques led to more than 90% of this cleanup. This accords with a 2013 report by the U.S. Energy Information Administration that shows dramatic reductions in air pollutants from electric power plants over the past two decades. Two pollutants in particular, SO2 and NOx emissions, fell dramatically -- from about 16 million short tons of SO2 and 6 million short tons of NOx in 1990 to about 3.4 million and 1.8 million, respectively, in 2012. The 1990 Clean Air Act Amendments clearly incented industry to develop new technologies that have led to a far more efficient and cleaner manufacturing sector. So the question isn't one of effectiveness, it's one of efficiency -- that is, as we become a cleaner society, how do we reduce pollution without reducing U.S. manufacturers' competitiveness? It's a very relevant question: The law of diminishing returns tells us that as more resources are invested on a fixed resource, you'll eventually reach a point at which additional investments yield progressively smaller results. In pollution control this means it's becoming progressively more expensive for manufacturers to eliminate their remaining emissions.

That brings us to EPA's proposed rules that would further tighten restrictions on smog-causing (i.e., ground-level) ozone, lowering allowable levels from 75 ppb to 65 ppb. Judging by EPA data, if the rules go into effect, three-quarters of the country would be unable to meet the new standard. Pursuing these remaining emissions will demand many, many more resources. Which is why, according to another study by NAM and NERA Economic Consulting, it could be the most expensive regulation ever imposed. A classic example of diminishing returns.

By introducing the most advanced technologies and processes in the world, the American factory sector has made tremendous strides in cleaning up its waste over the past two decades. As manufacturing pollution levels fall, their costs will continue to rise from the current tag of $25 billion per year. Policymakers need to take this, and the overall competitiveness of the sector, into consideration when pursuing their environmental goals.

Stephen Gold | President and Chief Executive Officer, Manufacturers Alliance

Stephen Gold is president and CEO of Manufacturers Alliance. Previously, Gold served as senior vice president of operations for the National Electrical Manufacturers Association (NEMA) where he provided management oversight of the trade association’s 50 business units, member recruitment and retention, international operations, business development, and meeting planning. In addition, he was the staff lead for the Board-level Section Affairs Committee and Strategic Initiatives Committee.

Gold has an extensive background in business-related organizations and has represented U.S. manufacturers for much of his career. Prior to his work at NEMA, Gold spent five years at the National Association of Manufacturers (NAM), serving as vice president of allied associations and executive director of the Council of Manufacturing Associations. During his tenure he helped launch NAM’s Campaign for the Future of U.S. Manufacturing and served as executive director of the Coalition for the Future of U.S. Manufacturing.

Before joining NAM, Gold practiced law in Washington, D.C., at the former firm of Collier Shannon Scott, where he specialized in regulatory law, working in the consumer product safety practice group and on energy and environmental issues in the government relations practice group.

Gold has also served as associate director/communications director at the Tax Foundation in Washington and as director of public policy at Citizens for a Sound Economy, a free-market advocacy group. He began his career in Washington as a lobbyist for the Grocery Manufacturers of America and in the 1980s served in the communications department of Chief Justice Warren Burger’s Commission on the Bicentennial of the U.S. Constitution.

Gold holds a Juris Doctor (cum laude) from George Mason University School of Law, a master of arts degree in history from George Washington University, and a bachelor of science degree (magna cum laude) in history from Arizona State University. He is a Certified Association Executive (CAE).
