U.S. emission testing

Advanced emission testing programs designed to increase compliance

Opus designs, builds and operates emission testing programs in states and counties across the U.S., tailored to local requirements. We work closely with our government partners to help them increase compliance with air quality standards and achieve their public policy goals. We pioneered many of the leading emission testing platforms used in the U.S., and led the development of remote sensing, which measures vehicle emission from the roadside as vehicles drive by in real world conditions.
