Working together with business & industry

A clean air success story

The Puget Sound Clean Air Agency is the primary entity responsible for regulating air pollution from business and industrial activities in King, Kitsap, Pierce and Snohomish counties.

Our programs, policies and regulations are designed to maintain air quality standards and protect human health. Working together with business and industry, significant air quality gains have been made in our region over the past few decades. Through a combination of technological innovations, emission reduction strategies and voluntary programs, business and industry now contribute less than 4 percent of total air pollution in our region.
