The California economy loses about $28 billion annually due to premature deaths and illnesses linked to ozone and particulates spewed from hundreds of locations in the South Coast and San Joaquin air basins, according to findings released Wednesday by a Cal State Fullerton research team.
Most of those costs, about $25 billion, are connected to roughly 3,000 smog-related deaths each year, but additional factors include work and school absences, emergency room visits, and asthma attacks and other respiratory illnesses, said team leader Jane Hall, a professor of economics and co-director of the university's Institute for Economics and Environment Studies.
The study underscores the economic benefits of meeting federal air quality standards at a time when lawmakers and regulators are struggling with California's commitment to protecting public health in a weak economy.
The $90,000 study does not propose any particular action. But in an interview, Hall said, "We are going to pay for it one way or the other. Either we pay to fix the problem or we pay in loss of life and poor health. . . . This study adds another piece to the puzzle as the public and policy-makers try to understand where do we go from here."
The California Air Resources Board is scheduled to vote Dec. 11 on whether to adopt broader rules that would force more than 1 million heavy-duty diesel truckers to install filters or upgrade their engines. Truckers and agribusiness have argued against stricter regulation, saying it is too expensive for them to invest in clean vehicles at a time of economic uncertainty.
Mary Nichols, chairman of the air resources board, said the findings will "be useful to all of us. Our board members hear on a regular basis from constituents who are concerned about the costs of regulations, and seldom hear from people concerned about their health because they are collectively and individually not as well organized."
In the meantime, the two regions continue to pay a steep price for generating air pollution ranked among the worst in the country. In the South Coast basin, that cost is about $1,250 per person per year, which translates into a total of about $22 billion in savings if emissions came into compliance with federal standards, Hall said. In the San Joaquin air basin, the cost is about $1,600 per person per year, or about $6 billion in savings if the standards were met.
