EU Roadworthiness Overhaul: Why Remote Sensing Targets Are Crucial for Cleaner Air

Introduction

In April 2025, the European Commission proposed a major revision of the EU Roadworthiness Package, introducing binding requirements for Member States to use remote sensing technology to screen vehicle emissions and noise. This move has drawn strong support from environmental NGOs and transport businesses alike, who warn that removing clear targets for remote sensing would undermine its potential to improve air quality across Europe.

The Air Quality Imperative

Road traffic remains one of the largest sources of harmful pollutants like nitrogen oxides (NOx), particulate matter (PM), and noise. Traditional inspection methods—such as periodic roadworthiness tests—often fail to capture real-world emissions because they are conducted under controlled conditions. Remote sensing offers a powerful complement: it can measure emissions from thousands of vehicles in actual driving conditions without stopping traffic.

Studies show that a well-designed remote sensing program can identify high-emitting vehicles with high accuracy, enabling targeted enforcement and repair. The European Commission’s proposal set specific binding targets for the proportion of vehicles screened annually, ensuring that the technology is deployed at scale. Without these targets, experts argue, Member States may underinvest in the technology, limiting its impact.

Health and Environmental Costs

Poor air quality is linked to hundreds of thousands of premature deaths in Europe each year, with transport as a major contributor. Reducing emissions from the worst-performing vehicles is one of the most cost-effective measures available. Remote sensing not only helps enforce existing standards but also provides data to track progress and identify emerging problems, such as the persistence of diesel cheating devices.

Broad Coalition Backs Strong Provisions

A diverse group of stakeholders—including environmental NGOs like Transport & Environment, consumer groups, and commercial transport operators—has voiced strong support for maintaining the remote sensing requirements. In a joint letter to Members of the European Parliament (MEPs), they stressed that “removing clear targets for the use of remote sensing would severely undermine its air quality benefits.”

Transport businesses, particularly those in logistics and fleet management, see remote sensing as a tool to improve fleet efficiency and demonstrate environmental responsibility. Many already use on-board diagnostics; remote sensing offers an independent, low-cost way to verify that vehicles remain compliant between inspections. NGOs, meanwhile, highlight the transparency and accountability that wide-scale screening can bring to the inspection market.

What Happens If Targets Are Softened?

If the binding targets are removed or weakened during the legislative process, the impact could be significant:

• Inconsistent adoption: Member States with weaker environmental priorities may opt out of substantial screening programs, creating a patchwork of enforcement across Europe.
• Reduced deterrent effect: The threat of being caught by remote sensing encourages drivers and fleet operators to maintain vehicles properly. Without scale, the deterrent fades.
• Lost data opportunities: Aggregated remote sensing data helps policymakers understand real-world emission trends, identify problem vehicle models, and calibrate future regulations. Small sample sizes reduce this value.

The proposal as originally drafted includes a clear roadmap for scaling up from 2026 onward. Delaying or watering down these provisions risks deferring air quality improvements for years.

A Call for Strong Action

As the European Parliament and Council deliberate on the Roadworthiness Package, the message from both environmental advocates and industry is clear: keep the remote sensing targets strong. The technology is mature, cost-effective, and proven. With proper targets, it can become a cornerstone of Europe’s strategy to clean up road transport and protect public health.

The coming months will determine whether the EU seizes this opportunity or settles for half-measures. For now, the coalition of NGOs and transport businesses continues to press for an ambitious outcome, arguing that clear, enforceable targets are the only way to guarantee that remote sensing delivers on its promise.
