UN Introduces New Regulation for Lifetime Monitoring of Vehicle Pollution

A new global regulation aimed at reducing vehicle pollution throughout a vehicle’s lifecycle has been adopted by the UNECE World Forum for Harmonization of Vehicle Regulations (WP.29) on March 11, 2026.

The regulation seeks to address the ongoing impact of vehicle emissions on air quality and public health by ensuring continuous monitoring and transparency of environmental performance. It introduces two key mechanisms: On-Board Monitoring (OBM) and the Environmental Vehicle Passport (EVP).

Key Measures Introduced

On-Board Monitoring (OBM) will provide continuous oversight of emission-related systems during real-world driving. It is designed to:

  • Track emission performance over time
  • Detect system malfunctions or deterioration
  • Alert drivers to excessive emissions or component failures

The system will monitor critical components such as catalytic converters and particulate filters. If issues are not addressed, vehicles may eventually be restricted from starting after 2,400 km of continued non-compliance.

Environmental Vehicle Passport (EVP) will serve as a digital, lifetime environmental record of each vehicle. It will include:

  • Type-approval data on emissions, CO₂ output, and energy consumption
  • Real-world emissions data based on vehicle usage
  • For electric vehicles, battery health indicators and energy use during non-driving operations

This passport will improve transparency for consumers and support resale value assessment, particularly for electric vehicles.

Key Deadline

  • Entry into force: By the end of 2026

What Companies Need to Do ?

Automakers and stakeholders in the automotive supply chain must begin preparing for compliance ahead of the 2026 deadline. Key actions include:

  • Integrate OBM systems into new vehicle designs to ensure real-time emissions monitoring
  • Develop EVP frameworks to collect, store, and share lifecycle environmental data
  • Ensure component durability, especially for emission-control systems like catalytic converters and filters
  • Align with type-approval requirements, including WLTP-based emissions and energy reporting
  • Prepare for data transparency obligations, ensuring vehicle owners can access environmental performance data

Industry Impact

The regulation is expected to drive innovation in emissions control technologies and digital monitoring systems while strengthening global efforts toward sustainable transport. By enforcing lifecycle compliance, the rule aims to significantly reduce real-world vehicle pollution and support cleaner mobility worldwide.
