The economic burden of pollution
Pollution is the leading environmental cause of disease and premature death, with air pollution causing 7 million premature deaths each year. More than 90% of these deaths occur in low- and middle-income countries. The economic burden of pollution-associated premature mortality and morbidity is significant, equivalent to 5 to 14% of countries' GDPs.
The World Bank estimates that outdoor air pollution kills roughly 5.7 million people globally each year, with economic costs equivalent to nearly 5% of global GDP, due to its impacts on health, productivity, and life expectancy. These impacts extend beyond health, affecting productivity and life expectancy, with an estimated global economic cost of $2.9 trillion, or 3.3% of the world's GDP.
In 2018, air pollution was linked to 4.5 million deaths, with PM2.5 pollution responsible for 1.8 billion days of work absence, 4 million new cases of child asthma, and 2 million preterm births. The economic burden of air pollution is evident in the form of increased healthcare costs, reduced labour force participation, and lower productivity. For example, the total annual cost of air pollution in China is estimated at $900 billion, equivalent to 6.6% of its GDP in 2018. Similarly, India bears an economic cost of $150 billion per year, or 5.4% of its GDP in 2018, while the US loses $600 billion annually, or 3% of its GDP.
The economic impact of pollution is not limited to air pollution. Lead exposure, for instance, may cost countries $6 trillion, equivalent to 6.9% of global GDP. Pollution from industrial activities, such as chemical production and manufacturing, also contributes to the economic burden. Furthermore, global waste is expected to increase to 3.4 billion tons by 2050, causing negative environmental impacts and hindering development outcomes.
Addressing pollution at its sources is crucial for enhancing economic growth, improving resource efficiency, and creating employment opportunities. Pollution management can alleviate poverty, boost shared prosperity, and deliver healthier and more productive lives for millions.

Environmental racism
The phrase "environmental racism" was coined by civil rights leader Dr. Benjamin F. Chavis Jr., who defined it as the intentional siting of polluting and waste facilities in communities primarily populated by people of colour and low-income workers. Study after study has shown that these communities are disproportionately exposed to fumes, toxic dust, ash, soot, and other pollutants from hazardous facilities located near them. As a result, they face increased risks of health problems like cancer and respiratory issues.
In the United States, some communities are continuously polluted, while the government gives little to no attention. Eminent sociologist Robert Bullard, known as the ""father of environmental justice", identified that environmental regulations are not equally benefiting all of society. People of colour are disproportionately harmed by industrial toxins in their jobs and neighbourhoods. This is due to institutionalised racism stemming from government and corporate policies that have historically favoured the health, well-being, and consumer choices of white communities over those of non-white, low-income communities.
Grassroots organizations and campaigns have brought attention to environmental racism in policymaking and emphasized the importance of minority input. The environmental justice movement, which developed in the 1970s and 1980s, was influenced by the earlier civil rights movement and sought to address the flawed environmental policies that have long harmed low-income communities and communities of colour.

Climate change and health
Climate change is a pressing global issue that poses significant risks to human health and well-being. It acts as a "threat multiplier," exacerbating existing health challenges and giving rise to new ones. The changing climate conditions are already impacting various aspects of health, from clean air and water to food systems and livelihoods.
One of the most prominent ways climate change affects human health is by increasing the frequency and intensity of extreme weather events, including storms, heatwaves, floods, droughts, and wildfires. These events directly contribute to injuries, respiratory and cardiovascular diseases, and premature deaths. They also indirectly impact health by disrupting ecosystems and natural resources, such as water and food systems, which are essential for human survival. According to the World Health Organization (WHO), climate change will cause approximately 250,000 additional deaths per year between 2030 and 2050 from undernutrition, malaria, diarrhoea, and heat stress alone.
The impact of climate change on health is not evenly distributed. Vulnerable populations, including women, children, older adults, marginalized communities, displaced persons, people with pre-existing health conditions, and those living in poverty, are at the greatest risk. Low- and middle-income countries, despite contributing minimally to global emissions, endure the harshest health consequences. This disparity is evident in the higher death rates from extreme weather events in vulnerable regions, which are 15 times higher than in less vulnerable areas.
Climate change also strains health systems, increasing the demand for health services while reducing their capacity to provide universal health coverage. The health sector itself contributes to climate change, responsible for approximately 5% of global greenhouse gas emissions. Transitioning health systems to low-carbon service delivery, such as adopting clean, renewable energy and low-carbon medical equipment, is crucial for mitigating climate change's impact on health.
Addressing the root causes of climate change and its health impacts requires a multi-sectoral approach. This includes improving transport, food, and energy use choices to reduce greenhouse gas emissions, as well as focusing on areas such as water sanitation, hygiene, and energy efficiency. By taking proactive measures, we can not only reduce the health risks associated with climate change but also promote healthier and more prosperous lives for millions of people worldwide.

The impact on low- and middle-income countries
Air pollution is a major threat to global health and prosperity. It is the leading environmental cause of disease and premature death. It is estimated to cause several times more deaths than AIDS, tuberculosis, and malaria combined. According to the World Health Organization (WHO), air pollution causes around 7 million premature deaths each year.
Low- and middle-income countries are disproportionately affected by the health risks of pollution. More than 90% of deaths caused by air pollution occur in these countries, with children being particularly vulnerable. In 2019, children younger than 5 years of age lost 765 million IQ points, averaging a loss of nearly 5.9 IQ points per child in low- and middle-income countries.
The sources of air pollution vary and are context-specific. In low- and middle-income countries, the major sources of outdoor pollution include residential energy for cooking and heating, vehicles, power generation, agriculture/waste incineration, and industry. The economies of these countries tend to rely more heavily on polluting industries and technologies, which contributes to higher levels of pollution.
The impact of pollution on low- and middle-income countries is not limited to health issues. Pollution also hinders development outcomes. Exposure to air pollution, water pollution, and hazardous chemicals and wastes like mercury, lead, and persistent organic pollutants (POPs) destroys ecosystems, creates harmful living conditions, and causes debilitating and fatal illnesses. The economic burden of pollution-related premature mortality and morbidity is significant, equivalent to 5 to 14% of these countries' GDPs.
Addressing pollution in low- and middle-income countries is crucial for alleviating poverty, improving health outcomes, and promoting sustainable development. Implementing targeted measures to reduce the pollution intensity of economic growth, such as supporting less polluting technologies and transitioning to cleaner fuels, is essential. Additionally, expanding access to affordable and adequate healthcare in large urban centers in these countries can help reduce mortality rates.
