On 29 September, UNDP presented Viet Nam’s second national air-pollution conference: around two hundred participants are discussing how to implement the 2026–2030 plan approved in November 2025. Topics include monitoring, forecasting and emissions inventories. [1]

WHO lists transport, industry and combustion among pollution sources. Coordinated measures can reduce them; a meeting and a plan alone do not demonstrate a measured improvement in air quality. [2][1]
