Air pollution caused by traffic, bad traffic situation and critical condition of shipping are two major issues in metropolises that have been emerged in recent years. Today, mobile sources of air pollution in the urban environment is the largest contributor in which programs and policies of the inspection and maintenance of vehicles cannot be separated from transport environmen...

Roadmap outlining steps to move Cambodia toward Euro 6/VI fuel quality and vehicle-emission standards, with an implementation timeline and stakeholder roles....

This TransportPolicy.net topic page serves as an index to jurisdiction- and vehicle-type–specific emissions standards pages (e.g., light-duty, heavy-duty, motorcycles, nonroad), helping users quickly find what standard is currently in force and navigate to supporting references.It’s useful for policy tracking, comparative research, and linking stakeholders to official or commonly cited regulatory ...

As vehicle pollution and fuel efficiency regulations have become more stringent, the technologies required to mitigate emissions and reduce fuel consumption become increasingly complex. One consequence is that government agencies around the world must improve their compliance and enforcement efforts to ensure that the intended outcomes from emission-control and fuel-efficiency programs are achieve...

UNITAR’s Fleet Safety Global Training Programme is a capacity-building initiative focused on improving fleet safety through the exchange of best practices and practical approaches used by major public and private sector fleets.​The programme is developed with Together for Safer Roads (TSR) and is linked to Vision Zero–oriented approaches for integrating safety into fleet management, with activitie...

On December 18, 2023, the European Parliament and the Council of the European Union (EU) reached an agreement on new emission standards for light- and heavy-duty vehicles. Pending formal adoption by both Parliament and Council, the new regulation will supersede the current Euro 6 regulation for passenger cars and vans, (EC) 715/2007, and the Euro VI regulation for trucks and buses, (EC) ...

China took a big step toward further reducing in-use vehicle emissions when it released a final notice of the establishment and implementation of a vehicle emissions inspection and maintenance (I/M) program in June 2020. The most important feature of this new program is that it establishes a closed-loop management mechanism whereby non-compliant vehicles must be repaired at an accredited main...

This briefing is a comprehensive technical overview of the Euro 6/VI vehicle emissions standards, which tighten limits on air pollutant emissions set in previous European standards and require the best technology currently available for vehicle emissions control.Countries outside of Europe, the United States and Japan have largely patterned their emissions policies on European regulations and the ...

Across the developing world, countries are experiencing rapid growth in urbanization and motorization. While high motorization rates potentially mean that more people will be able to claim the benefits of improved accessibility to goods and services because of enhanced mobility, there are questions about the sustainability of this future. From a development impact standpoint, the nature of a count...

This paper examines whether emerging transportation technologies—such as electric vehicles, shared mobility, and autonomous vehicles—deliver benefits equitably across different population groups. While these innovations offer efficiency, sustainability, and cost advantages, their distributional impacts remain uncertain, and existing equity evaluation methods lack clear comparability.Through a comp...
