Strategies Countries Use To Combat Air Pollution

Air pollution is a pressing issue that affects the health and well-being of people worldwide. In 2019, 99% of the global population lived in areas that did not meet the World Health Organization's (WHO) air quality guidelines. The impact of air pollution is disproportionately felt in low- and middle-income countries, with 89% of the 4.2 million premature deaths occurring in these regions in 2019. To combat this, countries are adopting various strategies to reduce air pollution and protect their citizens' health. These strategies include implementing policies for cleaner production, energy efficiency, and pollution control in industries, as well as promoting the use of cleaner technologies and renewable energy sources. Some countries are also electrifying public transport and encouraging active transportation, such as biking, to reduce pollution from private vehicles. These efforts are supported by organizations like the World Health Organization (WHO) and the World Bank, which provide resources, evidence, and funding to help countries improve their air quality.

Countries can encourage less reliance on private transportation

In addition to reducing air pollution, these initiatives can provide numerous benefits to society, such as lower traffic fatality rates, more active residents, and broader access to jobs, education, and urban services. Furthermore, public transportation is less expensive than owning a private car, safer, and allows riders to work or relax while traveling. It is also better for the environment, as buses and trains can reduce greenhouse gas emissions by up to two-thirds per passenger per kilometer compared to private vehicles.

To encourage the use of public transportation, countries can also implement policies and incentives that make it more attractive than private transportation. For instance, providing dedicated bus lanes, offering discounted or free public transport, and ensuring frequent and reliable service can all encourage people to leave their cars at home. Additionally, investing in active transport infrastructure, such as cycling lanes and pedestrian walkways, can further reduce the reliance on private transportation.

While implementing and expanding public transportation systems can be costly, the benefits outweigh the costs. Reducing air pollution can save countries billions of dollars in healthcare costs and increase productivity by reducing hospital admissions for asthma, respiratory diseases, and other illnesses caused by air pollution. Furthermore, with the right design choices, good public transportation can be self-reinforcing, attracting riders and encouraging transit-oriented development, which can lead to even greater reductions in private vehicle usage.

Overall, by investing in and promoting public transportation, as well as active transport options, countries can effectively encourage less reliance on private transportation, reducing air pollution and improving the health and well-being of their citizens.

Governments can implement clean air strategies

Secondly, governments can prioritize reducing emissions from transport, a major source of air pollution, especially in cities. This can be achieved by encouraging active travel, such as walking and cycling, and investing in public transport infrastructure, including electrifying bus and train networks. Additionally, governments can incentivize the use of electric vehicles and the development of clean energy vehicles, while also reducing the reliance on private transportation.

Thirdly, waste management strategies can be improved to reduce air pollution. This includes better management of urban and agricultural waste, as well as the implementation of policies to outlaw the burning of solid waste and the reduction of biomass burning for cooking, heating, and lighting. Governments can also work towards providing access to clean household energy, particularly in low- and middle-income countries, to reduce household air pollution and its associated health risks.

Furthermore, governments can address air pollution by targeting the reduction of specific pollutants, such as nitrogen dioxide, ozone, and particulate matter, which are known to have detrimental effects on human health. They can also work towards reducing the consumption of coal and other solid fuels, and prioritize the use of clean and renewable energy sources, such as natural gas.

Finally, governments can increase green spaces in urban areas, aiming for more trees and larger ratios of green space per person. This not only encourages a healthier lifestyle for residents but also helps absorb pollutants and improve air quality.

Cities can increase green spaces and tree coverage

Air pollution is a pressing issue, with countries and cities worldwide seeking ways to address it. While the focus is often on reducing emissions from transport, industry, and power generation, another crucial strategy is increasing green spaces and tree coverage in urban areas.

Trees and vegetation play a vital role in improving air quality. They act as natural filters, absorbing gaseous pollutants through tiny pores called stomata on their leaves. Trees can intercept and temporarily catch particulate matter, including harmful PM2.5, on their surfaces, preventing them from being inhaled. According to the U.S. National Park Service, urban forests can remove multiple tons of ozone, gaseous air pollution, and particulate matter annually. In addition, trees help reduce air temperature, mitigating the urban heat island effect and decreasing the formation of photochemical ozone. Lower temperatures also lead to reduced energy consumption in buildings, which, in turn, lowers air pollutant emissions from power sources.

The benefits of increasing green spaces and tree coverage in cities are significant. Firstly, they directly improve air quality by removing air pollutants. Secondly, they reduce air temperatures, which has a positive impact on human health and comfort. Thirdly, they encourage physical activity and provide mental health benefits to residents, potentially reducing socioeconomic health inequalities. Additionally, community gardens and green spaces foster social connections and provide access to nutritious food, further enhancing the well-being of city dwellers.

Some cities have already embarked on ambitious projects to increase green spaces and tree coverage. For example, Bangkok's Green Bangkok 2030 project aims to increase the ratio of green space to 10 sqm per person and have trees covering 30% of the city's total area. The project's first phase includes the opening of 11 new parks and a 15km greenway, encouraging less reliance on private transportation and, thus, reducing pollution. Similarly, Bogota, the capital of Colombia, is taking significant steps to reduce air pollution by electrifying its public bus network and promoting the use of bicycles.

By increasing green spaces and tree coverage, cities can effectively reduce air pollution, improve public health, and enhance the overall well-being of their residents. These initiatives not only save lives but also have economic benefits, reducing healthcare costs associated with air pollution-related illnesses.

Countries can outlaw the burning of solid waste

Air pollution is a pressing issue that affects the health and well-being of people worldwide. According to the World Health Organization (WHO), 99% of the world's population lived in areas that did not meet its air quality guidelines in 2019. Outdoor air pollution is estimated to have caused 4.2 million premature deaths worldwide in the same year, with 89% of those deaths occurring in low- and middle-income countries.

One way countries can effectively reduce air pollution is by outlawing the burning of solid waste. Open waste burning is a significant contributor to air pollution and has severe environmental and health impacts. The smoke from burning garbage, plastic, and painted or treated wood releases toxic chemicals, polluting the air we breathe. These pollutants can be inhaled by humans and animals, and they can also contaminate the soil, groundwater, lakes, rivers, and plants. Additionally, certain chemicals released during burning can accumulate in the fats of animals and subsequently enter the human food chain through meat, fish, and dairy products.

The negative consequences of open waste burning are evident in Lebanon, where the open burning of waste has disproportionately affected residents in lower-income areas. While wealthier areas have dumps that are not burned, nearly 150 open burn dumps are located in the poorest parts of the country. This has led to serious health risks, with residents feeling as though they are "inhaling their death." Lebanon's fire department received thousands of reports of open burning of waste, and the country has faced challenges in implementing an effective national solid waste management plan.

To address the issue of open waste burning, countries can implement several strategies. Firstly, raising public awareness through campaigns, environmental education, and regular inspections is crucial. Secondly, stronger policies and law enforcement, such as banning open waste burning and promoting recycling, are essential for a better solid waste management system. Thirdly, improving waste collection services can reduce the likelihood of people resorting to waste burning. Finally, community-level promotion of recycling activities at the household level can enhance overall waste management.

By outlawing the burning of solid waste and implementing comprehensive waste management strategies, countries can significantly reduce air pollution and mitigate the environmental and health risks associated with open waste burning.
