Clean Air

Keeping California’s Skies Clear

Clear Sky

Despite its many picturesque days, California has some of the dirtiest air in the nation. Three of the nation’s top five most polluting regions are located in California’s Central Valley*. About 10% of people living in the San Joaquin Valley alone are afflicted with chronic breathing disorders. Fresno County has one of the highest asthma death rates in the nation.

Reducing Pollution through Smarter Farming

Much of California’s air pollution comes from a somewhat surprising source: farming. Although it contributes to the problem, Sustainable Conservation is proving how farming can be part of the solution to promote clean air and healthy communities. Working with our alliance of agricultural, scientific and regulatory partners, Sustainable Conservation:

  • Promotes sustainable cultivation methods that cut dust and diesel emissions from farm equipment, including conservation tillage;
  • Researches and helps implement technologies to convert cow manure and other agricultural wastes into clean, renewable vehicle fuel to reduce air pollution from cars and trucks; and
  • Reduces nitrogen oxides and other air pollutants with on-farm technologies to improve air quality across the state.

The result? Dramatically cleaner air, healthier communities and a viable industry for those who grow and harvest our food.
