LIGHT DUTY: Independent real-world emissions analysis for passenger cars and vans
Understand how your vehicles perform beyond the laboratory
Passenger cars and light commercial vehicles behave in wonderfully unpredictable ways once they leave controlled environments. Traffic patterns, gradients, temperatures, driving styles and hybrid control strategies all influence real-world emissions. And these dynamics often reveal behaviours that formal procedures like WLTP cannot capture.
We use PEMS to measure second-by-second emissions in authentic, real-world driving conditions. This helps manufacturers, regulators and fleets understand how their vehicles perform under genuine loads, temperatures and road types.
Real Driving Emissions (RDE): Independent validation for Euro 6/VI and WLTP programmes, including temperature extremes and high-altitude conditions.
Hybrid and electrified powertrains: Insights into engine-on/off strategies, regenerative braking, battery thermal management and real-world range impacts.
Cold-start & urban cycle analysis: Understanding NOx, CO and PN profiles during congested driving and low-speed operation where emissions tend to peak.
High-load & high-temperature operation: Identifying emissions behaviours that emerge during steep gradients, motorway acceleration and hot climates.
Comparative benchmarking: Testing current vs previous model years, competitor vehicles or new calibrations to quantify improvements.
How we support your programme
What a typical light-duty PEMS test includes
Full PEMS package installation and calibration
Route selection designed around representative traffic and gradients
Real-time data capture for gaseous and particulate pollutants
Temperature, altitude and transient event correlation
Comprehensive engineering analysis
Clear recommendations for calibration refinement or compliance support
Optional extensions:
Multi-vehicle comparative testing
Ageing and deterioration studies

Software update verification
We test light duty vehicles across:
Europe
North America
South America
India
South East Asia
Australia
Whether you need dense urban traffic, rural gradients or desert temperatures, we can capture meaningful data from real-world duty cycles.
In addition to creating bespoke test cycles, we can replicate lab cycles such as WLTP on the road. Working with leading OEMs and emissions stakeholders, we also led the development of a cycle specifically for real-world comparison through CEN Workshop 90 – CWA 17379.
Working across diverse environments
Who we work with
Vehicle manufacturers
Tier 1 suppliers
Compliance and regulatory teams
Research organisations
Fleets and leasing companies
Our independent data helps teams validate performance, reduce risk and bring clarity to complex real-world behaviours.

‘Emissions Analytics carried out emissions testing on diesel generators coupled to our flywheel hybrid system. They took over the work at very short notice and showed great competence and professionalism in all stages of the project. Despite the novelty and peculiarities of our test requirements, their team showed great adaptability, attention to detail and provided excellent communication at all times.’
