A Story of an Engineering Congressman from Smoggy Los Angeles


Years ago the smog in LA was so thick and so persistant that the city was regarded as one of the worst cases of air pollution in the world. Out of that mix of environmental disaster, and damage to a generation of kids whose lungs were affected, came the beginnings of the modern environmental movement. Los Angeles and California were at the forefront of the first set of environmental laws, incl air quality. George E Brown, a mentor and friend for over 30 yrs, was a drafter of the original EPA legis and many other key initiatives that are now at the center of green politics. George would have had strong opinions about the latest moves in Congress to roll back the EPA...

Any regulation proposed by the Environmental Protection Agency follows a decades-long pattern. The activists squabble with the industrialists, pitting questions of business health against questions of public health. The squabbling plays out in newspapers and private lobbying meetings while the rules are drafted, and then it continues in court until somebody wins and somebody loses.

For America's biggest environmental law, however, economic health and public health haven't been locked in a zero-sum battle. The air is indisputably cleaner today, even after decades of economic growth. As the Obama administration tries to apply the Clean Air Act to a new environmental problem—climate change—it's worth wondering if past performance ever guarantees future results.

An annual report on air quality from the American Lung Association includes a revealing chart that tracks the percentage change in air pollution, gross domestic product, vehicle-miles traveled, population, energy consumption, and carbon dioxide emissions since 1970, when President Richard Nixon signed the Clean Air Act into law.
