Educating the public about the importance of energy efficiency and providing information on available incentives and programs can also help drive change.

Strengthen emission standards for vehicles

Emission standards for road vehicles, especially diesel light- and heavy-duty vehicles, should be strengthened. This can be achieved through the implementation of stricter regulations and the enforcement of mandatory vehicle checks and maintenance. Additionally, promoting the use of electric or hybrid vehicles and improving fuel efficiency standards can further reduce emissions and improve energy efficiency in the transport sector.

By implementing these measures and improving energy efficiency standards, Asia can significantly reduce air pollution, improve public health, and mitigate the damaging impacts of air pollution on the region's economy and environment.

Implement emission controls

The Asia-Pacific region has some of the highest recorded levels of air pollution in the world. Over 2.3 billion people in the region are exposed to levels of air pollution that are several times higher than the World Health Organization's (WHO) guideline for safe air. Fine particulate matter (PM2.5) and ground-level ozone are the two most damaging types of air pollution in the region.

To combat this, implementing emission controls is crucial. Here are some measures that can be taken to reduce emissions and improve air quality:

Industrial Emissions Standards

Introduce advanced emission standards in industries, such as iron and steel plants, cement factories, glass production, and the chemical industry. This includes improving the efficiency of brick kilns and implementing specific emissions standards for this sector.

Energy Efficiency Standards

Implement ambitious energy efficiency standards for industries. This includes encouraging the use of renewable energy sources and improving energy infrastructure to reduce emissions.

Vehicle Emissions Controls

Strengthen emission standards for road vehicles, with a particular focus on regulating diesel light- and heavy-duty vehicles. This can include incentives for the adoption of electric or hybrid vehicles, stricter fuel efficiency standards, and the implementation of low-emission zones in cities.

Post-Combustion Controls

Implement state-of-the-art end-of-pipe measures to reduce sulphur dioxide, nitrogen oxides, and particulate emissions at power stations and in large-scale industry. This includes the use of scrubbers, filters, and other technologies to capture and reduce emissions.

Vehicle Inspection and Maintenance

Enforce mandatory checks and repairs for vehicles to ensure they meet emission standards. This includes regular emissions testing and maintenance programs to identify and reduce emissions from older vehicles.

These measures, along with others, can significantly contribute to reducing air pollution in Asia. It is important to note that a combination of short-term and long-term strategies, as well as collaboration between governments, industries, and communities, is essential for effective and sustainable improvement in air quality.

Strengthen air quality management

Air pollution is a pressing issue in Asia, with over 2.3 billion people exposed to unsafe air, as per WHO guidelines. The two most damaging types of air pollution in Asia are fine particulate matter and ground-level ozone. Fine particulate matter, or PM2.5, is a group of microscopic substances primarily from the burning of fossil fuels and biomass, such as trees. Ground-level ozone is formed when fuel vapours, chemical solvents, and other pollutants are heated by the sun, creating smog.

To strengthen air quality management in Asia, the following measures can be implemented:

Conventional emission controls

Focus on emissions that lead to the formation of fine particulate matter (PM2.5). This includes reducing sulphur dioxide, nitrogen oxides, and particulate emissions at power stations and in large-scale industries. Introducing advanced emission standards in industries, such as iron and steel plants, cement factories, and chemical industries, can help reduce these emissions.

Energy efficiency standards for industries

Implement ambitious energy efficiency standards for industries to reduce their energy consumption and, consequently, their emissions. This includes promoting the use of clean fuels and renewable energy sources.

Strengthening emission standards for vehicles

Transportation emissions are a significant contributor to air pollution in Asia. By strengthening emission standards for vehicles, such as cars, trucks, and buses, we can reduce tailpipe emissions and improve air quality, particularly in urban areas.

Preventing peat and forest fires

Peat and forest fires contribute to air pollution by releasing particulate matter and gases such as carbon dioxide and nitrogen oxide. By implementing measures to prevent and effectively manage these fires, air quality can be improved.

Collaboration and knowledge sharing

Establishing networks and partnerships, such as the Asia-Pacific Clean Air Partnership, allows for collaboration and knowledge sharing between countries, networks, and initiatives focused on clean air in the region. This helps to identify and implement effective solutions to tackle air pollution.

Phase out fossil fuels

Fossil fuels are the primary driver of air pollution in Asia, particularly in the form of fine particulate matter (PM2.5) and ground-level ozone. These pollutants are released into the atmosphere through the burning of fossil fuels for power generation, industry, and transport, as well as the burning of biomass for cooking, heating, and lighting. As a result, over 2.3 billion people in Asia are exposed to unsafe levels of air pollution, causing millions of premature deaths each year.

To address this issue, a phase-out of fossil fuels is imperative. This involves a gradual global reduction in the use and production of fossil fuels, with the ultimate goal of reaching net-zero emissions. Many countries have already taken steps towards this goal by setting dates to stop selling petrol and diesel cars and trucks, and transitioning to electric vehicles. However, a timetable to stop burning fossil gas has not yet been agreed upon, and current efforts are not sufficient to meet climate goals.

To accelerate the transition away from fossil fuels, governments and stakeholders must work together to implement policies and initiatives that support the development and adoption of renewable and clean energy sources. This includes investing in wind, solar, and hydropower, as well as exploring alternatives such as electrification, green hydrogen, and biofuel. Additionally, improving energy efficiency and energy independence can complement the transition to sustainable energy sources.

The benefits of phasing out fossil fuels are significant. Not only will it reduce air pollution and improve public health, but it is also crucial to limiting global warming and mitigating climate change. Furthermore, it will reduce the economic burden associated with air pollution, which costs the world an estimated US$8 billion per day, or roughly 3.3% of the global GDP.

While the phase-out of fossil fuels is a challenging endeavour, it is a necessary step towards ensuring a sustainable future for Asia and the world. By working collaboratively and taking decisive action, it is possible to reduce air pollution, protect the health and well-being of citizens, and preserve the environment for future generations.
