Transition to Soot-free Heavy-duty Vehicles and Fuels: Regional Workshop for Southeast Asia
The International Council on Clean Transportation (ICCT) together with United Nations Environment Programme (UNEP) 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 ASEAN region. The ICCT is a non-governmental organization based on Washington D.C., that provides first-rate, unbiased research and technical scientific analysis to environmental regulators. Its mission is to improve the environmental performance and energy efficiency for 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. HDVs are responsible globally for 86% of on-road diesel NOx emissions and 78% of on-road diesel black carbon (BC) emissions, despite accounting for less than a quarter of the diesel vehicle fleet. For the Southeast Asian region, coordinated actions to harmonize technical regulations in trade blocs such as ASEAN could potentially enable a group of countries to progress faster than if each country were to develop technical regulations individually.
Alignment of vehicle emission standards, fuel quality standards, and used vehicle import policies among countries with strong economic ties could have added benefit of eliminating or reducing barriers to progress, such as competitiveness concerns, cross-border traffic, used vehicle markets, limited access to cleaner fuels, and limited availability of vehicle models meeting local design specifications.
These issues have been identified in the “Regional Training and Workshop; Transition to Soot-free Heavy-duty Vehicles and Fuels”, which was held virtually on 25–26 August 2021. The workshop was participated by Cambodia, Indonesia, the Philippines, and Vietnam. ASEAN Secretariat also participated the event as an observer.
