Developing World Pollution: Who's The Main Culprit?

Air pollution is a pressing issue worldwide, but it is particularly severe in developing countries. In fact, 98% of people in cities in developing nations live in areas where pollution exceeds WHO guidelines, compared to 56% in developed nations. This disparity is due to several factors, including lax regulations, lack of economic capacity, and the outsourcing of polluting industries from wealthier countries. The health consequences are dire, with air pollution causing millions of premature deaths and debilitating illnesses, especially in vulnerable populations such as women, children, and the elderly. Addressing this issue requires global cooperation, with developed nations playing a crucial role in enforcing standards and providing support to mitigate emissions and improve air quality in developing countries.

Lax regulations and poor government actions

The impact of these factors is exacerbated by the fact that, in large cities, the poorest often live in informal settlements near rubbish dumps, which are major sources of air pollution. This results in severe health consequences, with air pollution causing more than 9 million premature deaths globally, the majority of which occur in low- and middle-income countries. Inefficient cooking, heating, and lighting practices that use kerosene and solid fuels further contribute to indoor air pollution, leading to approximately 3.8 million deaths worldwide.

Weak environmental regulations can create a comparative advantage for polluting industries, attracting investment and economic growth at the expense of the environment and public health. Wealthier nations may also "outsource" their polluting practices to developing countries with cheaper labor and less stringent regulations, further exacerbating the problem.

To address these issues, the World Bank has been working with developing countries to improve air quality, reduce pollution, and promote sustainable practices. For example, the World Bank has supported projects in China, Egypt, and Peru to enhance air quality monitoring, reduce air pollutants, and increase energy efficiency. Additionally, the Montenegro Industrial Waste Management and Cleanup Project aims to improve hazardous waste disposal and strengthen regulatory frameworks.

While these efforts are commendable, more needs to be done to ensure that developing countries have the necessary resources and support to address pollution effectively. This includes meeting the $100 billion commitment made by wealthy nations to assist developing countries in mitigating and adapting to climate change.

Wealthy countries outsourcing dirty manufacturing

The outsourcing of dirty manufacturing processes by wealthy countries to the developing world is a significant issue that has sparked heated protests against the World Trade Organization. This practice, known as "carbon leakage" or "emissions transfers", involves wealthy nations shifting their carbon-intensive production to poorer countries, taking advantage of lower costs, larger workforces, and less stringent environmental regulations. While this may contribute to economic development and productivity gains in the host countries, it raises concerns about the environmental impact and the fairness of such practices.

During the early 2000s, emissions transfers were growing at an alarming rate of nearly 11% per year as Western manufacturing shifted to Asia. This trend saw factories in the US close down and reopen in China, with the manufactured goods then shipped back to the US. While this dynamic has stabilized since the 2008 financial crisis, it highlighted the ability of wealthy nations to report lower carbon emissions by increasing imports of carbon-intensive products like steel and cement.

The United States, in particular, has been accused of outsourcing its polluting industries to developing countries, taking advantage of "pollution havens." However, studies have challenged this notion, finding that the decline in domestic pollution-intensive manufacturing in the US has coincided with a decrease in imports of such goods from developing countries. This suggests that the US is not simply outsourcing its pollution but is also transitioning towards cleaner industries. Nonetheless, the complexity of global supply chains and the difficulty of measuring the carbon content of imported goods make it challenging to accurately attribute emissions across borders.

While industrialization and the shift towards manufacturing have been historically important for the development of poor countries, it is not the only path to economic growth. Service-led development, for example, is becoming increasingly popular, with countries like Costa Rica and the Philippines experiencing success in professional and technical services. Additionally, the large productivity gaps between rich and poor countries in manufacturing may limit the gains from solely focusing on industrialization.

To address the issue of wealthy countries outsourcing dirty manufacturing, various approaches have been suggested. One suggestion is to implement border adjustments or output subsidies for energy-intensive industries vulnerable to trade competition. However, such approaches come with their own legal, economic, and environmental challenges. Another proposal is to require detailed "environmental reviews" of trade agreements, ensuring that environmental considerations are central to the negotiating process.

Poor access to clean fuels and technology

The use of polluting fuels and technologies is a significant health risk, especially in low- and middle-income countries. According to the World Health Organization (WHO), 2.1 billion people worldwide lack access to clean cooking methods as of 2022. This figure represents a slight improvement from 1990, when over half of the global population relied on polluting fuels for cooking, to 26% in 2022. However, it is projected that one-third of the world's population will still be using polluting fuels by 2030, with the majority in Sub-Saharan Africa.

The lack of access to clean fuels and technology has severe health consequences. Household air pollution, caused by cooking with inefficient stoves and fuels like wood, coal, charcoal, dung, crop waste, and kerosene, leads to various diseases and premature deaths. The smoke inhaled from these polluting fuels is linked to heart disease, stroke, cancers, chronic lung diseases, and pneumonia.

The transition to cleaner alternatives, such as liquefied petroleum gas (LPG), in low- and middle-income countries (LMICs) faces several challenges. Firstly, there are financial barriers for both countries and users. The development of bottling plants, distribution networks, and refills incurs significant costs, and the affordability of refills for users needs to be considered. Secondly, the availability of biomass, the traditional fuel source, without monetary cost is a challenge, as transitioning to LPG requires a strong policy push, investments, and planning. Thirdly, improved cookstoves, such as forced draft stoves, may have higher efficiency and lower emissions but often require power or the creation of a local market for pallets, adding further costs.

While some LMICs, such as Brazil, China, India, Indonesia, and Pakistan, have made notable improvements in providing access to clean cooking methods, the rate of progress in other LMICs remains stagnant. This disparity contributes to health inequalities, as the local populations suffer the environmental and health consequences of dirty manufacturing and fuel sources while the goods they produce are consumed elsewhere.

Climate change and global warming

Developing nations face significant challenges in addressing pollution due to limited financial resources and inadequate government regulations. Lower-income countries often have lax regulations regarding air quality and vehicle emissions, and they lack basic air pollution controls in industries such as coal power plants. Additionally, income disparities within these countries result in people from lower socioeconomic backgrounds being more vulnerable to the health risks associated with pollution. They often reside in informal settlements near rubbish dumps, which are major sources of air pollution, and they lack access to cleaner fuels and technologies.

The health consequences of air pollution in developing countries are severe. According to the World Health Organization (WHO), ambient air pollution was responsible for approximately seven million deaths worldwide in 2012, with a significant proportion occurring in low- and middle-income countries. Indoor air pollution, caused by the burning of solid fuels for cooking, heating, and lighting, is a critical issue, particularly in rural areas. It leads to respiratory diseases, premature births, and slowed lung development in children. The economic impact is also substantial, with air pollution costing the globe an estimated $8.1 trillion in 2019, equivalent to 6.1% of global GDP.

To address these pressing issues, global cooperation and commitment are essential. Wealthier nations, which have historically emitted the majority of greenhouse gases, have an ethical responsibility to support developing countries in their transition away from fossil fuels. This includes fulfilling financial pledges, such as the $100 billion per year climate finance promise, to assist developing nations in mitigating and adapting to climate change. Additionally, systematic monitoring of air quality and the implementation of interventions to reduce air pollutant levels are crucial.

While the task is daunting, there is hope. The Beijing 2008 Olympic Games provide an encouraging example, demonstrating that maintaining air pollutant levels below certain thresholds can significantly reduce health-related economic costs. By working together and prioritizing action, the world can make a meaningful difference in combating climate change and global warming, ultimately improving the health and well-being of those most vulnerable to the impacts of pollution.

Poor health outcomes and premature deaths

Poor air quality has a significant impact on human health, causing debilitating and fatal illnesses, and contributing to harmful living conditions. According to the World Health Organization (WHO), respiratory and cardiovascular diseases, as well as cancer, caused by exposure to ambient PM2.5, led to approximately 4.2 million premature deaths in 2016. The majority of these deaths occurred in low- and middle-income countries.

The impact of air pollution on health is particularly severe in developing countries, where population growth, industrialization, and urbanization have resulted in crowded urban centers with poor air quality. More than three billion people, mostly in developing countries, rely on biomass fuels such as coal, wood, and other solid fuels for their energy needs, leading to high levels of household air pollution. This is especially detrimental to women and children in poor households, with studies showing a link between indoor air pollution and adverse pregnancy outcomes, including preterm birth, low birth weight, growth restriction, and potential cardiovascular and respiratory issues.

In addition to indoor air pollution, outdoor air pollution also poses a serious threat to health in developing countries. The combustion of solid biofuels, industrialization, use of pesticides and nitrogen-based fertilizers, crop residues, and inadequate waste management contribute to poor air quality. The economic burden of pollution-related premature mortality is significant, with the World Bank estimating that air pollution cost the globe $8.1 trillion in 2019, equivalent to 6.1% of global GDP.

The health consequences of air pollution are not limited to physical ailments but also extend to mental health. For example, research has shown that exposure to air pollution can lead to increased levels of anxiety, depression, and other mental health disorders. Furthermore, the impact of air pollution on health can result in a loss of productivity and economic growth, exacerbating poverty and inequality in affected areas.

Addressing air pollution and improving air quality are crucial to reducing the burden of disease and premature deaths in developing countries. This includes implementing interventions to reduce ambient and household air pollution, strengthening health systems, and promoting access to clean energy alternatives. Additionally, wealthy nations have a responsibility to assist developing countries in transitioning away from fossil fuels and mitigating the impacts of climate change, as their consumption patterns and emissions have contributed significantly to environmental degradation and health issues in the developing world.
