NOTRE VISION

OLFACTOMETRY AS DEFENSE

At Olf-Actions International Inc., we address odor challenges with what most overlook: engineering discipline, olfactometric science, and legal foresight.

With over 30 years of international experience and more than 5,000 odor-related mandates, we support cities, industries, and legal teams in building structured, defensible, and regulation-ready odor strategies.

🔺 Our team is multidisciplinary by design — environmental engineers, chemists, modelers, and legal experts working as one.
🔺 We work strictly within U.S. regulatory frameworks — nuisance law, air permits, zoning restrictions, and enforceable odor limits.
🔺 We produce court-grade technical evidence, suitable for litigation, compliance, or expert testimony.
🔺 And unlike many U.S. 'consultants' who rely on masking agents or chemical neutralizers, we sell no products — our independence is your strongest protection.

We don't just measure odors —
We defend environments, reputations, and operations.
