• Incentivising the use of electric vehicles (EVs): The government can offer tax breaks, subsidies, or other incentives to encourage the purchase and use of electric vehicles. This will help reduce emissions from transport as EVs produce zero emissions.
• Phasing out old vehicles: The government can provide subsidies or incentives for people to replace their old, polluting vehicles with newer, more fuel-efficient models. This will not only reduce emissions but also improve air quality.
• Implementing stricter emissions standards and regulations: Vietnam can set and enforce stricter emissions standards for vehicles, ensuring that all new and existing vehicles meet these standards. This may include regular emissions testing and stricter penalties for non-compliance.
• Improving traffic management: Measures such as improving traffic flow, reducing traffic congestion, and implementing intelligent transportation systems can help reduce emissions from idling vehicles. Optimising traffic signals and improving road infrastructure can also contribute to smoother traffic flow and reduced emissions.

By implementing these measures, Vietnam can significantly reduce emissions from transport and improve air quality in the country.

Improve indoor air quality

Improving indoor air quality is a crucial aspect of tackling Vietnam's air pollution crisis. Household air pollution is a serious health risk, causing an estimated 3.2 million deaths in 2020, with a disproportionate impact on children and women. It is caused by cooking with polluting solid fuels like biomass stoves, wood, coal, and crop waste, as well as the use of tobacco and the presence of pets and dust indoors.

To improve indoor air quality, Vietnam can implement the following measures:

• Promote the use of clean cooking fuels and technologies: The government can encourage households to transition from solid fuels to cleaner alternatives like liquefied petroleum gas, biogas, or electric stoves. Providing subsidies or offering incentives for adopting cleaner cooking practices can help accelerate this transition.
• Improve ventilation in homes: Increasing natural ventilation by opening windows and doors while cooking or using exhaust fans can help disperse pollutants and improve indoor air quality.
• Educate the public about the risks of indoor air pollution: Raising awareness about the health risks associated with indoor air pollution can empower individuals to take preventive measures. This includes understanding the importance of proper ventilation, the dangers of second-hand smoke, and the benefits of using cleaner cooking fuels.
• Encourage the use of air purifiers: In areas where outdoor air pollution is severe, the use of air purifiers can help reduce the concentration of harmful particles indoors. The government can consider providing subsidies or incentives for vulnerable groups, such as families with young children, to obtain air purifiers.
• Implement stricter controls on indoor tobacco smoking: Tobacco smoke is a significant contributor to indoor air pollution and poses serious health risks. Vietnam can strengthen smoking regulations by enforcing smoke-free public spaces and workplaces, increasing tobacco taxes, and offering smoking cessation programs to reduce overall tobacco consumption.
• Enhance indoor air quality monitoring: Developing guidelines and standards for indoor air quality can help raise awareness and encourage the adoption of healthier practices. Regular monitoring of indoor spaces, especially in public buildings, schools, and healthcare facilities, can ensure that air quality standards are met.

By implementing these measures, Vietnam can significantly improve indoor air quality, reducing the health risks associated with household air pollution and improving the overall well-being of its citizens, especially vulnerable groups such as children, pregnant women, and individuals with pre-existing health conditions.

Develop green spaces

Developing green spaces is an essential strategy to combat air pollution in Vietnam, a country that is among the top ten most affected by air pollution globally. The creation of green, open spaces in city centres is a recommended approach to purify the air and mitigate the health risks associated with poor air quality.

Relocating Industrial Sites

A crucial aspect of developing green spaces is the relocation of industrial sites away from city centres. Older industrial facilities, such as coal power plants, cement factories, and steel manufacturers, are being encouraged to move to designated industrial parks in the suburbs. This strategy not only helps reduce air pollution in densely populated areas but also contributes to the development of more sustainable and eco-friendly urban environments.

Improving Air Quality in Cities

The development of green spaces in Vietnam's cities can be a powerful tool to improve air quality and the overall well-being of residents. Green spaces act as natural air purifiers, absorbing pollutants and releasing oxygen, thereby reducing the concentration of harmful particles in the air. Additionally, they provide areas for recreation and social activities, promoting a healthier lifestyle for the population.

Reducing Greenhouse Gas Emissions

The establishment of green spaces can also contribute to Vietnam's efforts to reduce greenhouse gas emissions and combat climate change. Trees and plants absorb carbon dioxide, a major greenhouse gas, and act as carbon sinks, helping to mitigate the country's carbon footprint. This is particularly relevant given that Vietnam's greenhouse gas emissions are expected to triple by 2030, and the energy sector, including coal-fired power plants, is a significant contributor to air pollution.

Promoting Sustainable Development

The development of green spaces should be integrated into Vietnam's sustainable development agenda. By incorporating green spaces into urban planning, the country can create more liveable and environmentally friendly cities. This includes designing parks, green corridors, and rooftop gardens that not only enhance air quality but also provide spaces for community engagement, cultural activities, and environmental education.

Community Engagement and Education

Involving local communities in the development and maintenance of green spaces can foster a sense of ownership and encourage environmental stewardship. Educational programmes and awareness campaigns can be organised in these green spaces, empowering residents to take an active role in protecting their environment and reducing air pollution.

Implement environmental standards

The Vietnamese government is working on introducing environmental standards, rules, and regulations to address the country's air pollution problem. The Vietnam Minister of Natural Resources and Environment is leading the effort to implement a system that tackles air pollution. Here are some measures that can be included in this system to improve air quality:

Implement strict vehicle emission standards:

Vietnam's transportation system is a major contributor to air pollution, with the majority of vehicles being old and falling short of recommended emission standards. The government can enforce stricter emission standards for vehicles, incentivize the use of electric vehicles, and provide subsidies for the gradual phase-out of old, polluting buses and trucks.

Improve traffic control and management:

Traffic congestion and inefficient road planning exacerbate air pollution from vehicles. Improved traffic control measures, such as traffic signal optimization and road infrastructure enhancements, can help reduce congestion and minimize vehicle emissions.

Regulate industrial emissions:
