Who Provides PEMS Testing in Europe?
Portable Emissions Measurement Systems (PEMS) testing is used across Europe to measure vehicle emissions under real-world conditions. It plays an important role in understanding how emissions performance varies outside the laboratory, particularly in relation to regulatory frameworks such as Real Driving Emissions (RDE) and In-Service Conformity (ISC).
A range of organisations provide PEMS testing in Europe, each with a different role depending on whether the focus is regulatory compliance, engineering development, or independent measurement and research.
What is PEMS testing?
PEMS testing involves installing measurement equipment directly onto a vehicle or machine to record emissions while it is operating in real-world conditions.
Unlike laboratory testing, which follows fixed cycles in controlled environments, PEMS testing captures emissions across real driving scenarios. This includes variation in speed, load, terrain, temperature, and driving behaviour.
Because of this, PEMS testing is widely used to better understand how emissions perform in practice, rather than under idealised conditions.
Types of PEMS testing providers in Europe
Across Europe, PEMS testing is typically carried out by three main types of organisations.
Certification and regulatory laboratories
Certification laboratories conduct emissions testing as part of formal regulatory approval processes, which when reviewed in the context of PEMS, this often relates to RDE testing. Vehicles are assessed against defined regulatory boundaries under real-world driving conditions. These organisations operate within established compliance frameworks and follow prescribed testing procedures.
Their primary role is to determine whether vehicles meet regulatory requirements at the point of approval.
Engineering consultancies and technical service providers
Engineering consultancies use PEMS testing as part of vehicle development and optimisation. This testing is typically used to support manufacturers in understanding emissions performance during the design and calibration process. This can include identifying how emissions vary across different operating conditions and refining system performance accordingly.
The focus is often on development, diagnostics, and supporting technical decision-making during the product lifecycle.
Independent emissions testing organisations
Independent testing organisations use PEMS to measure real-world emissions outside of formal regulatory or development programmes.
There is an emphasis on objective measurement and analysis, often across a wide range of vehicles, technologies, and operating conditions. This can include comparative testing, research studies, and investigations into how emissions performance varies in practice.
By operating independently, these organisations provide an additional perspective on real-world emissions behaviour, complementing both regulatory testing and manufacturer-led development work.
Where Emissions Analytics fits
Emissions Analytics is an independent emissions testing organisation specialising in real-world measurement.
Using Portable Emissions Measurement Systems (PEMS), Emissions Analytics measures emissions directly from vehicles and machinery under real operating conditions. Its work focuses on understanding how emissions behave outside the laboratory, across different environments, duty cycles, and use cases.
This includes testing across passenger vehicles, commercial vehicles, and non-road mobile machinery, with a focus on producing comparable, data-led insights into real-world emissions performance.
By concentrating on independent measurement and analysis, Emissions Analytics contributes to a broader understanding of emissions behaviour, alongside regulatory testing and engineering development activities.
Why the distinction matters
While all three types of organisations use PEMS technology, their roles and incentives are different.
Certification laboratories focus on compliance within defined regulatory frameworks. Testing is conducted against prescribed conditions to determine whether requirements are met.
Engineering consultancies focus on development and optimisation, using PEMS to support calibration and improve system performance during the design process.
Independent testing organisations focus on measurement and analysis of real-world emissions behaviour, outside of both regulatory approval and product development cycles.
These differences shape not only how testing is carried out, but also the type of insight that is produced.
Regulatory testing is necessarily structured and bounded.
Development testing is often targeted toward improving specific outcomes.
Independent testing, by contrast, is designed to observe how emissions perform in practice, without being constrained by compliance objectives or optimisation goals.
This distinction becomes important when interpreting emissions data. Results generated under controlled or purpose-specific conditions do not always reflect the full range of real-world operation.
Independent PEMS testing helps bridge that gap by measuring emissions across a wider set of conditions, including variations in usage, environment, and behaviour. This provides a clearer view of how vehicles and machinery perform outside the laboratory.
For organisations seeking to understand real-world emissions performance, this type of measurement offers an additional layer of insight, complementing both regulatory testing and engineering development.
