2- Current status of air quality
3- Challenges • Main source of air quality pollution
in Ho Chi Minh City is from
transportation and the number of
private vehicles is increasing
significantly (also road
constructions)
• Public transportation has been not
developed correspondingly to
population increase and city
urbanization
• All roadside air monitoring stations
are semi-automatic. Ho Chi Minh
City lack of budget to invest an
automatic air quality monitoring
network
4- Whats’s next? The Priority Program to reduce
environmental pollution in the period of
2016-2020, targets:
• Reduce 70% air pollution caused by
transportation
• 90% of industrial emission sources will meet
environmental standards
• Develop a network of automatic air quality
monitoring stations and a shared database
• Develop transport infrastructure, awareness
campaigns to encourage citizens to use public
transport, etc.
