Revolutionizing On-Road Testing with PEMS Technology
Explore how Envirotest Transport’s Portable Emissions Measurement Systems deliver real-time, compliant, and efficient emissions testing solutions.
Real-World Emissions Testing with
Advanced Portable Measurement Solutions
Portable Emissions Measurement Systems (PEMS) are transforming how emissions data is gathered—delivering accurate, real-time insights under real-world operating conditions. These mobile systems enable on-board testing of regulated and unregulated pollutants during actual vehicle use, offering a more realistic alternative to laboratory simulations. In North America, PEMS solutions play a critical role in helping B2B clients—including government bodies, research institutions, OEMs, and fleet managers—monitor compliance, optimize performance, and support environmental initiatives. Designed for versatility and precision, today’s PEMS units combine advanced sensors, GPS integration, and cloud-ready analytics for seamless data handling. With growing demand for sustainable and regulation-ready operations, the importance of portable, adaptable emissions testing technology continues to rise. Supported by experienced engineering teams and trusted partnerships, our solutions ensure reliability in the field and alignment with evolving environmental standards—meeting the real-world needs of transportation stakeholders across North America.

Case Studies
California Heavy-Duty Fleet Emission Audits
In collaboration with a leading logistics provider in California, we deployed our PEMS across 45 diesel trucks to collect NOx and PM data. The study helped the client meet California Air Resources Board (CARB) requirements, resulting in a 23% reduction in regulatory fines and significant engine optimization across the fleet.
New York Metropolitan Transit Compliance Monitoring
Our PEMS were implemented in over 60 city buses operated by the NYC MTA. Real-time data integration helped detect peak emission events, enabling quicker mitigation. Compliance reporting was automated, helping the transit authority maintain consistent regulatory certification.
Canadian Mining Transport Emissions Optimization – Alberta
Working with a mining transport company in Alberta, our systems were installed in heavy-duty vehicles operating in extreme weather conditions. Emissions tracking allowed the client to re-tune engines for better fuel efficiency and reduced black carbon output, aligning with Canada’s Clean Fuel Standard goals.
