Air Pollution Control Measures From Around The World

Air pollution is a pressing global issue, causing an estimated 4.2 million premature deaths worldwide in 2019. While it is a problem in both developed and developing countries, the latter tend to be worse affected due to their growing economies and lack of economic resources to invest in cleaner fuel sources and emission-limiting technologies. To combat this, developing countries should focus on reducing industrial emissions, investing in renewable energy sources, improving public transportation, and promoting cycling and walking. Successful interventions in developed countries include setting pollution control standards for automakers and moving away from fossil fuels, particularly coal, which has led to a significant decline in energy emissions. The World Health Organization (WHO) plays a crucial role in providing evidence, building institutional capacity, and supporting countries in tackling air pollution through its Air Quality and Health Unit. Additionally, the European Parliament has adopted stricter air quality standards, and the United Nations Environment Programme (UNEP) is working towards improving air quality globally.

Developing countries should reduce emissions from industrial smokestacks

Air pollution is a significant problem in developing countries, with their citizens facing a higher risk of lung cancer, heart disease, stroke, and other health issues. According to the World Health Organization (WHO), around 89% of premature deaths due to air pollution occur in low- and middle-income countries. This is largely due to the high levels of air pollution in big cities in these countries, with almost all inhabitants exposed to poor air quality.

Developing countries should prioritize reducing emissions from industrial smokestacks to improve air quality and protect the health of their citizens. Industrial smokestacks, particularly tall stacks at coal power plants, release pollutants such as sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere. These pollutants contribute to acid rain, ozone depletion, and particulate matter, which have detrimental effects on human health and the environment.

To reduce emissions from industrial smokestacks, developing countries can implement several strategies. Firstly, they can invest in renewable energy sources, such as solar, wind, or hydroelectric power, to reduce their reliance on coal and other non-renewable energy sources. Secondly, they can install emission-limiting technologies, such as scrubbers, which are designed to control and reduce SO2 emissions. However, it is important to note that installing pollution control equipment can be expensive, and developing countries may struggle to balance this investment with their economic growth.

Another strategy is for governments to prioritize the development of healthy urban air. This includes implementing policies that support cleaner transportation, energy-efficient homes, improved power generation, and better municipal waste management. For example, providing options for cycling and walking in cities can help reduce the number of vehicles on the road and, consequently, decrease vehicle emissions. Additionally, improving access to clean household energy can significantly reduce ambient air pollution in certain regions.

By focusing on reducing emissions from industrial smokestacks and implementing other pollution-reducing strategies, developing countries can improve air quality, protect the health and well-being of their citizens, and contribute to the protection of the global climate and environment.

Invest in renewable energy sources

Air pollution is a significant issue in developing countries, which tend to have higher levels of air pollution than developed countries. This is partly because developing countries are still growing their economies and often lack the economic resources to invest in cleaner fuel sources and emission-reducing technologies.

One way to combat air pollution is to invest in renewable energy sources. Renewable energy sources are available in all countries and can be derived from natural resources like the sun, wind, water, waste, and heat from the Earth. These sources are replenished by nature and emit little to no greenhouse gases or pollutants into the air. According to the United Nations, renewable energy sources could provide 65% of the world's electricity supply by 2030 and decarbonize 90% of the power sector by 2050, significantly reducing carbon emissions and improving air quality. The International Renewable Energy Agency (IRENA) estimates that 90% of the world's electricity should come from renewable sources by 2050.

Investing in renewable energy can also have economic benefits, such as creating more jobs in the clean energy sector and driving inclusive economic growth. For example, every dollar invested in renewables creates three times more jobs than in the fossil fuel industry. Additionally, renewable energy sources can help countries diversify their economies and protect themselves from unpredictable fossil fuel price swings.

Furthermore, investing in renewable energy can improve health outcomes and reduce healthcare costs associated with air pollution-related ailments. According to the World Health Organization (WHO), about 99% of people worldwide breathe air that exceeds recommended air quality limits, and air pollution causes more than 13 million deaths annually. By reducing air pollution, renewable energy sources can help mitigate these health risks and improve life expectancy.

Overall, investing in renewable energy sources is a crucial step towards addressing air pollution, improving environmental health, and promoting sustainable economic growth.

Prioritise rapid and communal transit

Air pollution is a pressing issue worldwide, with 99% of the world's population breathing unclean air. It is a particular concern in developing countries, where air pollution is worse and continues to deteriorate. This is due to a variety of factors, including the rapid growth of economies and populations, the lack of economic resources to invest in cleaner fuel sources and technologies, and the prioritization of cheap energy production over clean energy production.

One way that countries can combat air pollution is by prioritizing rapid and communal transit. This involves investing in and promoting public transportation systems, such as buses, trains, and subways, to reduce the number of private vehicles on the road. This approach has been successful in the United States, where the Environmental Protection Agency (EPA) has implemented stringent standards for vehicle pollution control under the Clean Air Act of 1970. As a result, new passenger vehicles are now 98-99% cleaner for most tailpipe pollutants compared to the 1960s.

Developing countries can also prioritize rapid and communal transit by constructing dedicated bus lanes, implementing bus rapid transit systems, and offering subsidies or incentives for public transportation use. These measures can help reduce traffic congestion, improve air quality, and provide efficient and affordable transportation options for citizens. Additionally, investing in the development of electric or hybrid public transportation fleets can further reduce emissions and improve air quality.

Another strategy to prioritize rapid and communal transit is to create pedestrian- and bicycle-friendly infrastructure. This includes constructing and maintaining sidewalks, bike lanes, and bike-sharing programs, as well as implementing policies that prioritize the safety and convenience of pedestrians and cyclists. By encouraging active transportation, countries can reduce the number of vehicles on the road, decrease emissions, and improve the health and well-being of their citizens.

Furthermore, countries can invest in the development of smart transportation systems, utilizing technologies such as ride-sharing apps, real-time transit information, and intelligent traffic signals. These systems can optimize transportation networks, reduce traffic congestion, and improve the efficiency of communal transit. Additionally, providing incentives for carpooling and promoting telecommuting or flexible work arrangements can help reduce the number of vehicles on the road and further improve air quality.

Provide options for cycling and walking in cities

Air pollution is a significant problem worldwide, and it is particularly severe in developing countries. The World Health Organization (WHO) states that approximately four out of five people living in cities do not meet its air quality guidelines. Moreover, 98% of people in poor and developing nations and 56% in developed countries live in areas with poor air quality.

One effective way to tackle this issue is to provide options for cycling and walking in cities. This can be achieved through the following measures:

Infrastructure and Urban Design

Urban spaces should be designed to meet daily needs, such as jobs, education, healthcare, and access to goods and services, within distances that can be safely covered by active mobility means and public transport. This may involve reallocating space for cycling and walking, improving active mobility infrastructure, and increasing the safety of cyclists and pedestrians. For example, providing secure parking for bikes at destinations and near public transport can encourage people to choose active travel options.

Safe Infrastructure for Cyclists and Pedestrians

The legacy of car-centric road planning has created dangerous conditions for pedestrians and cyclists, especially in cities. To address this, bureaucratic processes that slow down the implementation of safe infrastructure, such as bike lanes and traffic calming measures, should be streamlined. This will help reduce traffic fatalities and make people feel safer when choosing to walk or cycle.

Green Spaces and Trails

Green spaces, parks, and trails can also promote walking and cycling indirectly. For example, the Cobbs Creek Trail in Philadelphia connects the city with the John Heinz National Wildlife Refuge, providing a valuable community resource that encourages active travel.

National Cycling and Walking Plans

Countries should develop comprehensive plans to promote cycling and walking, secure the necessary resources, and allocate responsibilities for implementation. This can include integrating cycling into health policies and urban and transport planning, as outlined in the Pan-European Master Plan for Cycling Promotion.

By implementing these measures, cities can effectively provide options for cycling and walking, reducing air pollution and improving the health and well-being of their residents.

Developed countries invest in cleaner fuel sources

Developed countries are more likely to invest in cleaner fuel sources and technologies that limit emissions because they have the economic resources to do so. Developing countries often struggle with air pollution due to their growing economies, and investments in cleaner fuel sources can come at the cost of economic growth. Therefore, it is crucial to balance economic growth and air quality to protect the health and standard of living of citizens in developing nations.

One example of a developed country investing in cleaner fuel sources is the United States. The US budget for clean energy investments exceeds $559 billion, with investment in low-carbon electricity projects accounting for over a third of this. Additionally, almost a quarter of the total investment is dedicated to developing low-carbon and efficient transport systems. The US has also promoted the use of low-sulfur fuels and the introduction of cleaner vehicles through partnerships such as the Partnership for Clean Fuels and Vehicles (PCFV).

Germany is another developed country that has made significant investments in clean energy. While Germany has faced challenges due to its dependence on fossil fuel supplies from Russia, it has allocated around $17 billion to fuels and technology innovation. This includes efforts to improve building and industrial efficiency and develop clean transport systems.

These investments in cleaner fuel sources and technologies have had positive impacts on air quality and human health. For instance, the phase-out of lead from gasoline globally has resulted in economic benefits from preventing lead exposure in children. Additionally, the reduction of sulfur in fuels has significantly lowered sulfur dioxide and particulate matter emissions, which have important impacts on human health.

Overall, developed countries' investments in cleaner fuel sources and technologies play a crucial role in improving air quality and protecting the health and well-being of citizens, both domestically and in developing nations.
