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.

1. 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.

2. 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.

3. 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.

Tyre Emissions & Sustainability USA 2026 Program Now Live as Industry Prepares to Meet in Irvine This April

The full program for Tyre Emissions & Sustainability USA 2026 is now live, confirming a two-day agenda dedicated to one of mobility’s most urgent and fast-evolving challenges: tyre emissions, chemical composition and lifecycle sustainability.

Taking place at the Beckman Center in Irvine, California, the conference will bring together leading scientists, regulators, material innovators and industry specialists to examine the environmental and health impacts of tyre wear and to explore practical pathways forward.

With the event fast approaching in April, delegates can now review the confirmed speaker line-up and session topics across chemistry, testing, air quality, regulation and circularity.

Tyres are increasingly recognised as a major source of non-exhaust emissions, shedding millions of tonnes of material globally each year  . At the same time, regulatory scrutiny is intensifying. Legislative developments, including emerging limits on tyre wear and chemical oversight in multiple jurisdictions, are accelerating research and innovation across the sector.

Against this backdrop, the 2026 program has been structured to move beyond headlines and into data, methodology and real-world evidence.

The central questions being addressed include:

• How well do we understand tyre wear particle generation and distribution?

• What is the environmental fate of compounds such as 6PPD and 6PPD-quinone?

• How should testing methodologies evolve?

• What would genuine lifecycle circularity look like in practice?

The newly released program confirms contributions from leading institutions across the United States and internationally.

Speakers include:

• Dr Susanne Brander, Project Director at The Pew Charitable Trusts and Courtesy Faculty at Oregon State University

• Stephanie Gordon, Physical Scientist at US Geological Survey

• Seth Hankla, Environmental Scientist at California Department of Toxic Substances Control

• Aaron Puhala, Vice President of Innovation at Arclin

• Professor Georgios Karavalakis and Elizabeth DeFrance from University of California Riverside

• Professor Zhenyu Tian, Northeastern University

• Professor Punyaslok Rath, University of Missouri-Columbia

• Denise Kennedy, President & CEO of DK Enterprises

• David Stevens, Managing Director of Tire Retread & Repair Information Bureau

• Erik Krogh, Vancouver Island University

• Dr Rachel Scholes, University of British Columbia

• Dilraj Surendran, Tokyo Metropolitan University

Sessions will cover:

• National 6PPD-Q mapping and vulnerability analysis

• Tyre wear particulate measurement

• High-throughput chemical analysis in urban waters

• Air quality impacts of non-tailpipe emissions

• Artificial turf crumb rubber transformation

• Retreading, recycling and the practical realities of circularity

Day one focuses on tyre chemistry, testing methodologies and infrastructure. Day two expands into air quality effects, formulation, end-of-life management and lifecycle circularity.

The structure reflects a simple principle: the tyre question cannot be solved in isolation. It sits at the intersection of materials science, toxicology, hydrology, air quality, regulation and industrial design.

Rather than approaching tyre emissions as a single-variable problem, the conference positions it as a systems challenge. Each session builds another layer of understanding, much like examining a tyre cross-section. The surface tells one story, but the compounds, interactions and downstream pathways reveal a much more complex picture.

Tyre Emissions & Sustainability USA is organised by Emissions Analytics, known for its independent testing and real-world data programs  . The conference series was created to provide a structured, evidence-based forum at a time when environmental debates are becoming increasingly politicised.

Founder and CEO Nick Molden commented:

“Environmental discussions around tyres are accelerating quickly. What matters now is the quality of evidence and the clarity of testing methods. Our goal is to create a space where primary research, regulatory thinking and industrial realities can be examined carefully and constructively.”

With the program confirmed and April approaching, registration is open for delegates wishing to attend in Irvine, CA on 22–23 April 2026  .

The event includes access to all presentations, electronic copies of materials, networking breaks and lunch and an evening cocktail reception.

Group discounts remain available.

Off-Highway & Power Generation USA 2026 Programme Now Live as Industry Prepares to Meet in Indianapolis This May

The full programme for the 3rd Off-Highway & Power Generation USA 2026 conference is now live, confirming a comprehensive two-day agenda focused on energy-agnostic decarbonisation across non-road machinery and stationary power.

Taking place on 20–21 May 2026 at the Sheraton Indianapolis City Centre Hotel, the event will convene regulators, OEMs, fuel specialists, powertrain engineers and technology providers to examine what meaningful emissions reduction looks like in practice.

With May approaching, delegates can now review the confirmed speaker line-up and detailed session structure spanning ICE, electrification, renewable fuels and power generation technologies.

Off-highway machinery remains heavily reliant on diesel, yet alternatives are advancing rapidly. Electrification, hybridisation, biofuels and e-fuels are all progressing, each with its own technical, economic and lifecycle questions.

At the same time, power generation is under renewed scrutiny. The exponential growth in energy demand, particularly from data centres and AI infrastructure, has placed stationary engines and backup generation firmly in the spotlight.

The 2026 programme has been structured to reflect that reality. This is not a single-technology conference. It is a systems discussion about performance, durability, regulation and commercial viability.

Much like an off-highway duty cycle, the path to decarbonisation is rarely linear. It requires balancing load, terrain, fuel availability and regulatory pressure. The agenda is designed to explore those trade-offs openly.

Day One: Regulation, Powertrains and Electrification

The first day opens with a regulatory and market outlook, including:

• Kim Heroy-Rogalski, Chief, Mobile Source Regulatory Development Branch at California Air Resources Board

• Allen Schaeffer, Executive Director of Engine Technology Forum

• Dr Graham Conway, Director, Industrial Sustainability at Opportune LLP

Powertrain developments feature contributions from:

• Professor Dr Greg Shaver, Purdue University

• Dr Danan Dou, John Deere Power Systems

• Chris Sharp, Southwest Research Institute

Afternoon sessions move into abatement, ICE and electrification, with speakers from:

• Proventia

• Cambustion

• Volvo Construction Equipment

• Ymer Technology

• Convergent Science

Sessions will address topics including hydrogen combustion NOx variability, advanced exhaust aftertreatment, thermal management for electrification and simulation-led optimisation tools.

Day Two: Power Generation Under Pressure

The second day shifts focus to stationary power and decarbonisation.

Confirmed contributors include representatives from:

• Johnson Matthey

• Rolls-Royce Solutions America Inc.

• Cummins Inc.

• Dinex Emission Inc.

• EPRI

• Neste US

• Innospec Fuel Specialities

• Kaizen Clean Energy

Sessions will examine:

• The evolution of the stationary power market

• Emissions from gensets in data centre applications

• Emerging fuels and gas turbines

• Renewable diesel as an immediate carbon reduction pathway

• Dispatchable off-grid microgrids

• Catalyst technologies ready for future fuels

A concluding leaders’ panel will address a central question: how can the power generation industry make meaningful emissions reductions while meeting urgent customer demand?  

Off-Highway & Power Generation USA was launched to provide a neutral meeting place for non-road stakeholders at a time when energy debates are often polarised.

Organised by Emissions Analytics, an independent real-world emissions testing specialist, the conference reflects a clear principle: focus on measurable outcomes rather than rhetoric.

From Portable Emissions Measuring Systems for NRMM to laboratory fuels analysis, the company’s testing background informs the conference structure, ensuring discussions are grounded in data, comparability and practical implementation  .

Registration is now open.

With the full programme now confirmed and May fast approaching, registration is open for delegates wishing to attend in Indianapolis on 20–21 May 2026  .

The delegate pass includes:

• Access to all presentations

• Electronic copies of materials

• Refreshments throughout

• Evening networking reception

Group bookings are available.

Tear down the sign!

The capacity to stop pretending

Every morning, this shopkeeper places a sign in his window: “Workers of the world unite.”  He doesn’t believe it, no-one does, but he places a sign anyway to avoid trouble, to signal compliance, to get along.  And because every shopkeeper on every street does the same, the system persists – not through violence alone, but through participation of ordinary people in rituals they privately know to be false.

Mark Carney, prime minister of Canada, was quoting Czech dissident and subsequent Czech president Václav Havel in his special address at the World Economic Forum in Davos in January 2026. 

Since perhaps 1997 and the Kyoto Protocol we have arguably been “living within a lie,” as President Havel put it when referring to how the post-War Communist regime could sustain itself.  Not because climate change is unimportant, nor that other environmental challenges around air, water and soil pollution and biodiversity can be ignored, but because we collectively have been pursuing policies that we know are not working.  Most vexingly, everyone in power still clings to net zero, just as citizens are beginning to take their window signs down: …the old order is not coming back.

We can argue at length as to how severe the threat from climate change is – noting that none of the International Panel for Climate Change scenarios forecast planetary extinction – and whether electrification of vehicles or decarbonisation of the electricity grid through solar and wind are the optimal policy responses. That is not the point of this article. Emissions Analytics has long proposed, based on its real-world test data, that hybrid electric vehicles are the optimal solution for the immediate future, and there is no true route to decarbonisation without a very significant expansion of nuclear fission energy generation.

The deeper question is how so many current environmental policies are sustained when they are obviously not working. More specifically, how can environmental laws be maintained when they are perennially violated. It is perhaps no surprise, then, that citizens are increasingly discontent with their political systems.

What is increasingly clear is that, in 2026, for the world of environmental rules and emissions reduction, things have fundamentally changed. It is ironic that the individual calling this change towards “strategic autonomy” is a Canadian prime minister who has historically been a major proponent of global net zero policies.

He was personally responsible for embedding net zero into the core of financial policy and institutions, particularly through his leadership at the Bank of England and later as the UN Special Envoy for Climate Action and Finance. As Governor of the Bank of England, he helped reframe climate change as a systemic financial risk rather than a purely environmental issue, driving early work on climate stress testing, scenario analysis, and stronger expectations for climate-related disclosure across the banking and insurance sectors. In his UN role, he extended this agenda globally by mobilising private finance for the transition, including co-founding the Glasgow Financial Alliance for Net Zero (GFANZ) at COP26, which brought together major financial institutions to align lending and investment with net-zero goals.

Yet, in January 2026, he is saying: Friends, it is time for companies and countries to take their signs down… We participated in the rituals, and we largely avoided calling out the gaps between rhetoric and reality.

While he was talking about the rupture in the rules-based order generally, net zero arguably forms part of that order, and so he might as well have been talking about net zero specifically. The fact is that the world is currently not close to meeting its obligations under international climate change treaties, particularly the Paris Agreement, which aims to limit warming to well below 2°C and ideally 1.5°C. While most countries have submitted climate plans (NDCs) and reporting systems are improving, the combined commitments remain far too weak, putting the world on track for roughly 2.3-2.9°C of warming this century rather than meeting the agreed targets. Emissions continue to rise in many regions, enforcement mechanisms are limited and global cooperation is weakening.

But this is not just a question of being off track on one, albeit important, international treaty. Not meeting environmental laws has become institutionalised, extending beyond climate change to other areas of environmental legislation such as air, water and chemicals. Just two examples are that most member states of the EU have failed fully to implement the Marine Strategy Framework Directive (Directive 2008/56/EC) that required Member States to achieve Good Environmental Status (GES) of EU marine waters by 2020, and there is still persistent and widespread non-compliance with the 1991 Nitrates Directive (91/676/EEC) that targeted reducing nitrate pollution from agriculture to protect water quality. In England, the Office for Environmental Protection, a watchdog that was set up in 2021, has concluded that the country is “largely off track” for seven out of its ten Environmental Improvement Plan goals for 2023, with the remaining three goals only “partially on track.” These goals cover biodiversity, air, water, chemicals and pesticides, resource wastage, climate change and biosecurity.

A legally binding environmental target is at risk of being little more than a rhetorical device if it is not supported by a clear enforcement mechanism. If governments can miss the target without penalties, if no institution is truly accountable for delivery, and if failure carries no concrete consequences, then the “binding” nature of the commitment becomes largely meaningless. In that sense, a target can exist in law while remaining effectively optional in practice.

Proponents often point to indirect forms of enforcement — judicial review, statutory duties, reporting requirements or oversight bodies — but these mechanisms frequently amount to weak substitutes for genuine compulsion. Courts can rarely force governments to achieve outcomes, only to revise plans or explain themselves, and transparency alone does not guarantee action. Too often, legally binding targets end up binding process rather than performance: governments are required to publish strategies, not to deliver results. Without clear sanctions or automatic regulatory triggers, the practical force of such targets remains doubtful.

You may ask why a government would not want to meet its own environmental target? Most likely, the true direct costs and indirect economic and social effects may have been underestimated, or that the government department or agency did not have the appropriate skills. Witness the current struggle to 95% decarbonise the UK electricity grid by 2030 – setting such a tight deadline doomed the government to have to overpay for infrastructure. We also must consider the possibility that there was never an intention to address to the target, but it was announced anyway for political gain.

Non-compliance is not cost-free. Assuming the target was socially desirable in the first place, any period of non-exceedance is sub-optimal. It also may punish organisations that have met legal requirements, creating a free-rider benefit for those who have not met the target – an unfairness. The act of having to defend non-compliances in the face of the judiciary or public opinion via campaign groups, takes up significant time and resources of ministers, officials and parliamentarians, which could be better spent.

What should we conclude from this? Is it that governments are just over-ambitious in setting environmental goals and poor at implementing policies to meet them? Or is this all just evidence of a deeper game, where power can be sustained despite little foundation by maintaining a collective delusion? Either way, it is easy to see when citizens in many countries are increasingly disillusioned with their governments.

What is the solution?  One side might bludgeon the other into submission.  Net zero as currently set up might win in the face of popular opposition.  Conversely, climate denial voices might harness popular discontent, and environment policies gutted as a result.  What may be a better outcome is to acknowledge citizens’ instincts, priorities and pressures and strike a fundamentally pragmatic balance between environmental and social damage.  Drop the dogma.  Drop the moralising.  Focus on real-world effects, realistic costs, deliverable plans, pragmatic compromises.  And deliver.  In doing so, trust can be rebuilt.

As a final thought, Mark Carney was perhaps the natural person to call an end to our collective delusion about the rules-based international order, as someone central in building the net zero edifice but who became prime minister of Canada, a country that pulled out of the Kyoto Protocol in 2012.  We have, as he rightly said: the capacity to stop pretending.

Critical Mass Wins 2026 Independent Press Award

We are proud to share that Critical Mass: The One Thing You Need to Know About Green Cars has been named a 2026 Independent Press Award Winner. 

In an era where climate change dominates global discussion, Critical Mass sees Felix our CEO, Nick Molden and Felix Leach unpack the complexity of vehicle emissions with clarity and rigour. Building on insights from Felix’s previous work, Racing Toward Zero, the book tackles the often-confusing landscape of automotive pollution by asking a deceptively simple question: what single piece of information best captures the true environmental impact of cars? 

Written for a digital age awash with information but eluded of meaningful understanding, Critical Mass challenges oversimplified narratives around road transport and sustainability. Leach and Molden advocate for a more sophisticated, yet accessible perspective about emissions, examining the real-world impacts of different vehicle powertrains and moving beyond CO₂ alone to consider wider environmental and societal effects. 

The Independent Press Award recognises excellence in independent publishing and honours books that demonstrate strong editorial quality, originality, and relevance. Being selected as a 2026 winner reflects the growing importance of transparent, factual analysis in climate and mobility discussions.
