A study by the Political Economy Research Institute at the University of Massachusetts Amherst named Fairfield conglomerate General Electric as the No. 3 air polluter in America.
The institute's fourth annual Toxic 100 Air Polluters index assesses how many toxins are released by each company, how hazardous the toxins are, and how many people are at risk. The companies are ranked on the overall amount of toxins, so businesses with multiple facilities end up higher on the list.
GE landed at No. 3 on the list behind German-owned Bayer Group and Textron, Inc. GE has facilities all over the world, but the study only looked at its American emissions.
Other Connecticut-headquartered companies on the list include Northrop Grumman Corp. (No. 10), Praxair Inc. (30), United Technologies Corp. (38), and Stanley Black & Decker (46).
