Transition to Soot-free Heavy-duty Vehicles and Fuels: Regional Workshop for Southeast Asia
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. The disproportionate contribution of HDVs to air-quality issues is a key reason for their prioritization by the Climate and Clean Air Coalition (CCAC) Heavy Duty Vehicles Initiative (HDVI).
In the case for 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.
