Decades of Clean Air Progress Threatened


Clean Air Act of 1970

Beginnings of the environmental movement coming out of 1960s activism.

A tip of our eco-hat to citizens (and Congressman George Brown, an East LA engineer) who envisioned what could be accomplished to clean up the air.

Here's to citizens and scientists working to clean up our air and water, protecting our environment for the health of all... in Los Angeles, the US and in nations across the world.


Back in the 1950s and '60s, people in Los Angeles breathed some of the dirtiest air in the world.

Los Angeles still has smog, of course, but it’s not nearly as bad as it used to be. How did the city get its act together?

It took decades. Los Angeles had its first real smog attack during World War II, a smog strong enough that some people suspected a Japanese chemical attack. But it wasn’t until 1975 that the U.S. required new cars to have catalytic converters, “the key piece of technology that allowed everything to change,” according to Mary Nichols, chairman of California’s Air Resources Board. In between, there were frustrating years of scientific research, industry denial, politics, protest and an unwavering attachment to the automobile.
