California Cars, Air Cleaner, Smog Alerts Down

-- California automobiles produce fewer emissions than those they replace and California's air has grown progressively cleaner with far fewer smoggy days over the past two decades, according to data from the California Air Resources Board (ARB).

The state’s large population, number of vehicles, warm weather and unique air basins make many parts of California ideal for producing smog. That is why California started earlier and works harder than other regions of the nation to control air pollution. California has the nation’s most stringent  emission standards for motor vehicles and many other products that produce smog-forming emissions.

“Clear progress can be seen -- people who have lived here any length of time realize there’s less smog than before,” said Michael Kenny, ARB Executive Officer. “We have the cleanest cars, the cleanest-burning fuel, we even have the cleanest lawnmowers,” he said. Kenny pointed out some of the areas where California has made significant progress in reducing air pollution: 


101 Days


83 Days


41 Days


14 Days

1999 to Today


“It’s obvious that our job is not over. With our population growing and the world’s fifth largest economy we have to energize people and develop new technology to keep making progress for cleaner air,” said Kenny.

The Air Resources Board is a department of the California Environmental Protection Agency. ARB’s mission is to promote and protect public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. The ARB oversees all air pollution control efforts in California to attain and maintain health based air quality standards.

The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption. For a list of simple ways you can reduce demand and cut your energy cost, see our website at
