While developing countries are responsible for a significant amount of worldwide pollution, it is important to recognize the historical context and the role of wealthy nations. Just 23 developed countries are responsible for half of all historical CO2 emissions, and they continue to have higher per capita emissions compared to developing nations. The adverse effects of pollution are more severely felt in developing countries, with higher death rates and a significant impact on health, particularly in large cities. This disparity is due to various factors, including weaker environmental regulations, a lack of access to clean technologies, and the vulnerability of impoverished communities. Addressing pollution in developing countries requires a multifaceted approach, including international cooperation, the implementation of standards, and the promotion of sustainable practices.

Air pollution in developing countries kills 7 million people annually
Air pollution is a leading cause of death worldwide, with approximately 7 million deaths attributed to it annually. The majority of these deaths occur in low- and middle-income countries, with 89% of the 4.2 million premature deaths caused by ambient air pollution taking place in these regions.
Developing countries are disproportionately affected by air pollution, with industrializing economies experiencing particularly high levels. This is due to a combination of factors, including less stringent air quality regulations, the use of older polluting machinery and vehicles, congested transport systems, and rapidly developing industrial sectors. The health impacts of air pollution are severe, increasing the risk of cardiovascular and respiratory diseases, and causing inflammation not only in the lungs but throughout the body, which can lead to non-communicable diseases such as stroke and heart disease.
Indoor air pollution, caused by the burning of solid fuels for cooking and heating, is also a significant issue in developing countries. Around 50% of people in these countries rely on coal and biomass, such as wood, dung, and crop residues, for domestic energy. Incomplete combustion of these materials leads to high levels of indoor air pollution, with women and children being particularly vulnerable. Indoor air pollution increases the risk of chronic obstructive pulmonary disease and acute respiratory infections, posing a serious threat to the health of those residing in developing nations.
The impact of air pollution on developing countries is further exacerbated by limited access to quality healthcare services. The interplay between air pollution and poverty cannot be overstated, as the adverse health effects of air pollution are compounded by poverty risk factors and inadequate healthcare. Moreover, occupations requiring physical outdoor labor expose individuals to higher levels of air pollution, further endangering the health and well-being of those in developing nations.
Addressing air pollution in developing countries necessitates global cooperation and government intervention. Wealthier nations have an ethical responsibility to assist developing countries in mitigating and adapting to the impacts of climate change, as they have emitted the majority of greenhouse gases. By providing funding, enforcing air quality standards, and promoting cleaner technologies, developed nations can help reduce emissions and protect the lives of those most vulnerable to air pollution.

Developing countries are hit hardest by climate change
The latest report from the Intergovernmental Panel on Climate Change (IPCC) states that the climate crisis is widespread and intensifying. The planet has warmed by 1.1C above pre-industrial levels, and atmospheric carbon dioxide levels are the highest they have been in at least 2 million years. The report warns that human-induced changes to the climate system are unprecedented, and climate extremes are affecting every region.
Developing countries are on the frontline of the climate crisis. They are disproportionately affected by extreme weather events, such as cyclones, droughts, and flooding, which are becoming more frequent and severe due to climate change. These events have devastating impacts on lives and livelihoods, food security, and economic development. For example, in the Pacific, Small Island Developing States (SIDS) are being battered by king tides and rising sea levels, threatening the very existence of low-lying nations such as Kiribati and the Marshall Islands.
Climate change also exacerbates existing social and economic inequalities, making it harder for developing countries to escape poverty. The World Bank estimates that by 2030, the effects of climate change could push an additional 100 million people below the poverty line. Extreme weather events cause consumption losses of $520 billion annually and push 26 million people into poverty each year. Climate-driven migration is also on the rise, with 80 million people displaced from their homes, according to security experts.
Furthermore, developing countries often lack the resources and technology to transition to clean and renewable energy sources. They may be forced to choose between short-term economic gains and investing in more expensive, cleaner infrastructure. This is where developed countries have a responsibility to step in and provide financial support. At the 2009 United Nations climate summit, wealthy nations promised to provide $100 billion annually by 2020 to help developing countries adapt to climate change. However, this promise has not been fulfilled, and developing countries continue to call for financing to tackle the climate crisis.
The impacts of climate change on developing countries are far-reaching and devastating. It is crucial that the international community takes decisive action to support these vulnerable nations and address the disproportionate impacts of climate change.

The effects of pollution are worse in less-developed areas
While pollution is a global issue, the effects are disproportionately worse in less-developed areas. Developing countries face unique challenges, such as rapid and unregulated economic expansion, that contribute to higher levels of pollution and more severe consequences.
One of the primary reasons developing nations struggle more with pollution is the tension between economic growth and pollution reduction. These countries often prioritize cheap energy production to ensure competitive prices for their citizens, which often comes at the cost of environmental sustainability. Fossil fuels, particularly coal, are favored for their affordability and accessibility, despite being major contributors to pollution. The infrastructure in these countries is also rapidly expanding, making it difficult to implement cleaner and more efficient energy sources. In contrast, developed nations have already addressed these challenges and can focus more on environmental considerations.
The health impacts of pollution are more acute in less-developed areas. Air pollution limits each person's life expectancy by an average of two years, with the effects being worse in developing countries. In Bangladesh, India, Nepal, and Pakistan, air pollution reduces citizens' life expectancy by an average of five years, with similar trends observed in parts of China and Iran. The high levels of air pollution in these countries are linked to millions of deaths and hospitalizations annually. Additionally, indoor air pollution, caused by burning solid fuel for cooking and heating, accounts for 6% of all deaths in developing countries.
The lack of access to clean fuels and technology exacerbates the problem. Only 60% of the world has access to clean fuels, leaving many in developing countries reliant on solid fuels for their daily needs. This contributes to indoor air pollution, which has detrimental effects on respiratory health, particularly for children and those with pre-existing conditions. Furthermore, the poor air quality in these areas increases the likelihood of contracting respiratory illnesses, such as COVID-19, and reduces the body's ability to fight off infections, leading to higher death rates.
The effects of pollution on the environment are also more pronounced in less-developed areas. The rapid expansion of economies and populations in these regions leads to unsustainable growth, making them primary sources of environmental damage. The dominant "take, make, waste" linear economy contributes to the depletion of natural resources and causes negative environmental impacts throughout the product lifecycle. As a result, ecosystems in these areas are severely damaged, hindering development outcomes and exacerbating the challenges faced by local communities.

Indoor air pollution causes 6% of deaths in developing countries
Air pollution is a significant global issue, and it is having an increasingly detrimental impact on human health. In 2021, air pollution was the second leading risk factor for death, causing 8.1 million deaths worldwide, including children under five. It is estimated that air pollution reduces each person's life expectancy by two years on average, with the effects being worse in less-developed areas.
Indoor air pollution, caused by the burning of solid fuels for cooking and heating, is a major contributor to this issue in developing countries. Around 50% of people in developing countries rely on coal, wood, dung, and crop residues for energy, which, when burnt, release harmful pollutants. Women and children are particularly vulnerable to indoor air pollution as they are typically responsible for household chores such as cooking and collecting firewood.
Indoor air pollution causes a range of adverse health effects, including an increased risk of chronic obstructive pulmonary disease (COPD), acute respiratory infections, low birth weight, pulmonary tuberculosis, and lung cancer. It is estimated that indoor air pollution causes 6% of all deaths in developing countries, accounting for 1.6 million deaths each year.
To address this issue, the World Health Organization (WHO) provides support to countries to evaluate and scale up the use of health-promoting household fuels and technologies. The WHO develops guidelines for indoor air quality and provides recommendations on fuels and technologies that protect health. Additionally, the WHO maintains a global household energy database to monitor the transition to cleaner fuels and stove combinations.
While death rates from air pollution are falling, even in the most polluted countries, more government involvement and partnership are needed to combat the adverse effects of air pollution in developing countries. Developed nations must cooperate and enforce higher standards of air quality to promote health and protect the lives of people globally.

Wealthy countries have emitted the majority of greenhouse gases
Wealthy countries, particularly the United States and Western European nations, have emitted the majority of greenhouse gases that have led to the climate crisis. Just 23 developed countries are responsible for half of all historical CO2 emissions.
The United States has emitted a quarter of all historical emissions, according to estimates from the World Resources Institute, and should pay as much as 47% of the $100 billion per year that wealthy nations pledged to mobilize by 2020 to help developing countries reduce their emissions and adapt to climate change. However, wealthy nations failed to meet this target, with only about $80 billion mobilized by 2019.
While China is currently the largest emitter of greenhouse gases, wealthy nations have historically grown rich by burning fossil fuels. The United States and many countries in Europe had higher emissions in the past but have reduced their emissions in recent years due to stricter environmental regulations. In contrast, China's emissions have increased due to its rapid economic growth. Wealthy nations' historical emissions have significantly contributed to the climate crisis, and they bear a large responsibility for its impacts.
Developing nations are being hit hardest by the effects of climate change and are the least prepared to respond. They often lack the resources and access to clean fuels and technology, which puts them at greater risk and undermines their economic development. For example, in developing countries, 98% of city dwellers live in areas where pollution exceeds WHO guidelines, compared to 56% in developed nations. The effects of pollution are severe, with air pollution causing approximately 7 million deaths worldwide each year and reducing life expectancy by two years on average.
To address these disparities and support developing countries in mitigating the impacts of climate change, wealthy nations must fulfill their funding commitments and provide additional assistance to vulnerable nations.
