The air quality is deteriorating in Vietnam’s big cities and major industrial zones, and this would severe negative impacts on people and the economy, it said in a proposal that is being reviewed by various government agencies.
Emissions from vehicles and factories are one of the biggest causes, it said.
The country has 5.1 million cars and a large number of motorbikes, 120,000 factories - of which 138 have been identified as having severe environmental impact - and 110,000 construction firms.
Charging a fee on emissions is therefore necessary, and should start with chemical and mining companies, it said.
It has recommended a basic fee of VND3 million ($126) a year on these companies, and another VND500,000-800,000 in case of extra emissions.
It would bring around VND1.2 trillion annually to the government’s coffers and the money would be used to mitigate the environmental impacts, it added.
