Based in Bridgeton, Mo., Hunter Engineering Company is a world leader in wheel alignment, wheel and tire service, inspection and ADAS calibration equipment. A certified veteran-owned business, Hunter has been building automotive service equipment in the USA since 1946, with sustainability at the core of its culture through the employee-led Hunter Green Team. It is the only company in St. Louis Green Business Challenge history to complete three different achievement levels in three consecutive years, and its work in 2025 earned Champion Level status in the 2025 Challenge.
A major milestone came when Hunter obtained ISO 14001 Certification. “Achieving ISO 14001 Certification was a true highlight for our company in 2025 as this enabled us to formalize our Environmental Management System (EMS) as an organization,” said Chip Hiemenz, Vice President of Hunter Engineering. “We look forward to building upon this foundation in 2026 and beyond.” That mindset runs through the company, which says environmental responsibility is an integral part of how it designs, engineers, manufactures and supports its products, guided by a commitment to continual improvement, reducing environmental impacts and conserving resources.
To build on that foundation, Hunter formalized its Environmental Policy mission statement and areas of focus. The company also established 2025 Environmental Objectives with a formal timeline and tracking system, and constructed an Environmental Continual Improvement Plan involving both manufacturing and employee engagement.
Employees played a key role in putting those plans into action. Hunter conducted Environmental Awareness training through its Learning Management System (LMS) platform and established Environmental Best Practices for manufacturing operations and office areas, featuring energy conservation, resource conservation and waste reduction.
Hunter’s impact also reaches beyond its own walls. Since joining the PrintReleaf program, the company has reforested 1,822 standard trees. Hunter also facilitated Challenge engagement for the Donald Danforth Plant Science Center, helping another local organization take part in the program.
These efforts build on years of work at Hunter. Over the past two years, the company has replaced thousands of inefficient fluorescent and metal halide fixtures with LEDs, cutting lighting energy use by 40-70% in upgraded facilities. Hunter has also reduced its server and PC footprint through virtualization, for estimated power savings of 5.0 million kWh annually, replaced an older boiler with high-efficiency condensing models to reduce natural gas use by 40%, and recycled more than 46,000 pounds of electronics since 2019.
