UL is at the forefront, focusing on the impact of products on people and the environment. We understand the potential threat indoor air pollutants pose, which is particularly relevant because most people spend approximately 90 percent of their time indoors where air is typically two to five times more polluted than it is outdoors. Poor indoor air quality in commercial buildings and schools can lower worker productivity, adversely impact learning and worsen allergy and asthma symptoms. To address these important and growing issues, we have developed a comprehensive and leading-edge indoor air certification program for buildings.

UL has developed more than 1,000 Standards. Thousands of products and their components are tested
to our rigorous requirements every year.
