The World Health Organization (WHO) highlights the significant health risks associated with household air pollution, primarily resulting from the use of inefficient and polluting fuels and technologies for cooking, heating, and lighting. In 2020, approximately 2.1 billion people—about one-third of... the global population—relied on open fires or inefficient stoves fueled by kerosene, biomass (such as wood, animal dung, and crop waste), and coal. This exposure led to an estimated 3.2 million deaths, including over 237,000 deaths of children under the age of five. The pollutants emitted from these sources contribute to a range of health issues, including respiratory infections, heart disease, stroke, chronic obstructive pulmonary disease, and lung cancer. The WHO emphasizes the urgent need for transitioning to cleaner fuels and technologies to mitigate these health risks.

Air pollution is the top environmental threat to health in Europe. It leads to hundreds of thousands premature deaths per year and billions of Euros in health costs.
Air pollution is one of the leading causes of health complications and mortality worldwide, especially affecting lower-income groups, who tend to be more exposed and vulnerable. This study documents the relationship between ambient air pollution exposure and poverty in 211 countries and territories.... Using the World Health Organization’s (WHO) 2021 revised fine particulate matter (PM2.5) thresholds, we show that globally, 7.3 billion people are directly exposed to unsafe average annual PM2.5 concentrations, 80 percent of whom live in low- and middle-income countries. Moreover, 716 million of the world’s lowest income people (living on less than $1.90 per day) live in areas with unsafe levels of air pollution, especially in Sub-Saharan Africa. Air pollution levels are particularly high in lower-middle-income countries, where economies tend to rely more heavily on polluting industries and technologies. These findings are based on high-resolution air pollution and population maps with global coverage, as well as subnational poverty estimates based on harmonized household surveys.

Although air pollution is well known to be harmful to the lung and airways, it can also damage most other organ systems of the body. It is estimated that about 500,000 lung cancer deaths and 1.6 million COPD deaths can be attributed to air pollution, but air pollution may also account for 19% of all... cardiovascular deaths and 21% of all stroke deaths. Air pollution has been linked to other malignancies, such as bladder cancer and childhood leukemia. Lung development in childhood is stymied with exposure to air pollutants, and poor lung development in children predicts lung impairment in adults. Air pollution is associated with reduced cognitive function and increased risk of dementia. Particulate matter in the air (particulate matter with an aerodynamic diameter < 2.5 μm) is associated with delayed psychomotor development and lower child intelligence. Studies link air pollution with diabetes mellitus prevalence, morbidity, and mortality. Pollution affects the immune system and is associated with allergic rhinitis, allergic sensitization, and autoimmunity. It is also associated with osteoporosis and bone fractures, conjunctivitis, dry eye disease, blepharitis, inflammatory bowel disease, increased intravascular coagulation, and decreased glomerular filtration rate. Atopic and urticarial skin disease, acne, and skin aging are linked to air pollution. Air pollution is controllable and, therefore, many of these adverse health effects can be prevented.

Air pollution is a major environmental risk factor and contributor to chronic, noncommunicable diseases (NCDs). However, most public health approaches to NCD prevention focus on behavioural and biomedical risk factors, rather than environmental risk factors such as air pollution. This article discus...ses the implications of such a focus. It then outlines the opportunities for those in public health and environmental science to work together across three key areas to address air pollution, NCDs and climate change: (a) acknowledging the shared drivers, including corporate determinants; (b) taking a ‘co-benefits’ approach to NCD prevention; and (c) expanding prevention research and evaluation methods through investing in systems thinking and intersectoral, cross-disciplinary collaborations.

A systematic review of the evidence has demonstrated the key role of clean household energy in improving global health, reaffirming the importance of United Nations’ Sustainable Development Goal (SDG) 7, to achieve worldwide access to affordable, modern and clean energy by 2030.
This report presents an overview of the state of air quality and its impacts on health in Africa.
The global burden of disease associated with air pollution exposure exacts a massive toll on human health worldwide: exposure to air pollution is estimated to cause millions of deaths and lost years of healthy life annually. The burden of disease attributable to air pollution is now estimated to be ...on a par with other major global health risks such as unhealthy diet and tobacco smoking, and air pollution is now recognized as the single biggest environmental threat to human health.

According to the 2016 Nepal Demographic and Health Survey, 66% of Nepali households use mainly solid fuel for cooking on inefficient stoves. Incomplete fuel combustion of solid fuels emits greenhouse gases and harmful smoke, contributing to climate change, forest degradation, ill health and preventa...ble deaths. Further, the physical burden and time necessary to collect wood for fuel is borne primarily by women and children, thus compromising their productive time, such as social activities and education.

Almost the entire Rwandan population (98.5%) relies on polluting fuels, particularly firewood and charcoal, for cooking. Access to clean energy such as electricity is still limited. In 2022, 70% of the population lived in towns and villages that have electricity – 49% from the national grid and 21...% from off-grid (mainly solar) systems. When access is defined as connection and use of households to electricity, an estimated 47% of households had access in 2020, representing 86% of the urban population but only 38% of the rural population.
