Online and United Nations Conference Centre, Bangkok, Thailand

The United Nations Environment Programme (UNEP) and the International Council on Clean Transportation (ICCT) are implementing a project funded by the Climate and Clean Air Coalition (CCAC) to address the issue of emissions from heavy-duty vehicles and fuels in the Association of Southeast Asian Nations (ASEAN) region. 

The United Nations Environment Programme (UNEP) is the leading global environmental authority that sets the global environmental agenda. It is the secretariat of the Partnership for Clean Fuels and Vehicles (PCFV), which is the leading global public-private initiative promoting cleaner fuels and vehicles in developing countries and countries in transition. 

The United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) is the most inclusive intergovernmental platform in the Asia-Pacific region and is extending policy support to Asia-Pacific countries to accelerate their transition to electric mobility in public transport, as part of a project on electric mobility and the Asia Pacific Initiative on Electric Mobility.

The ICCT is a non-governmental organization based in Washington DC, that provides first-rate, unbiased research and technical scientific analysis to environmental regulators. Its mission is to improve the environmental performance and energy efficiency of road, marine, and air transportation to benefit public health and mitigate climate change. 

Heavy duty diesel vehicles move a large share of people and goods, yet this reliance on diesel technology comes with significant environmental and health cost. Heavy duty vehicles (HDVs) are responsible globally for 86% of diesel NOx emissions and 78% of diesel black carbon (BC) emissions from the roads, despite accounting for less than a quarter of the diesel vehicle fleet. The disproportionate impact of HDVs on air quality presents a great opportunity for ASEAN region.

These issues have been identified in a series of workshops and training organized by UNEP and ICCT between August 2021 and August 2022, covering the topics on fuel and vehicle emissions standards, electrification, and the adoption of Euro VI for HDVs in ASEAN.

One of the key findings from the above workshop is that the adoption of a more stringent standard (Euro VI) combined with improvement of fuel quality is a key option to achieving soot-free vehicles. Vehicle electrification has also been identified as an important solution to achieving soot-free and zero-emission transport in the region.

Objective and scope

The key outputs from this side event are:

  1. Enhanced knowledge of the key government officials (Ministry of Transport) about the status of the vehicle emission standards and fuel quality, particularly for HDVs in the ASEAN subregion.
  2. To discuss opportunities and challenges toward a harmonized approach for Euro VI standards and the transition to electric vehicles in ASEAN countries.
  3. To discuss collaboration opportunities among the relevant transport authorities in the ASEAN Region 

Event format and time

This event is a side event during the ESCAP Seventh Session of Committee on Transport, which will be held in Bangkok during 23-25 November 2022.

This side event is a hybrid event with participants coming from the transport ministries that are involved in the issue of vehicle emissions, fuels, and transport electrification from the ASEAN region, as well as the ASEAN Secretariat, UNESCAP, UNEP and ICCT. 

The event will be held on 24 November 2022 from 12.30 to 14.00 (Bangkok or UTC +7).
