Air quality and health impacts of heavy-duty vehicles in G20 economies

On-road diesel vehicles are the leading contributor to air pollution and associated disease burdens. Besides the impact on air quality and public health, black carbon from diesel engine exhaust produces significant near-term climate warming. This study analyzes the health and climate impacts associated with projected diesel HDV exhaust emissions in G20 economies under four scenarios: currently adopted policies, expanded adoption of Euro VI-equivalent standards, potential next-generation emission standards, and accelerated fleet renewal programs.
