Fossil fuels are a major source of air pollution, releasing harmful substances such as nitrogen oxides, sulfur dioxide, and particulate matter into the atmosphere when burned. These emissions contribute to smog, acid rain, and poor air quality, leading to respiratory issues, cardiovascular disease, and cancer. The health impacts are particularly severe for children, with fossil fuel pollution causing respiratory infections, impairing cognitive and behavioral development, and resulting in other chronic diseases. According to research, air pollution from burning fossil fuels is responsible for about one in five deaths worldwide, with vulnerable communities disproportionately affected. The environmental impacts of fossil fuels extend beyond air pollution, contributing to climate change, water contamination, and the destruction of animal habitats. However, there is growing momentum towards cleaner energy sources and policies that aim to reduce emissions and mitigate the harmful effects of fossil fuels on our air, health, and planet.

Fossil fuel combustion is the leading environmental threat to children's health
Fossil fuels, including coal, oil, and natural gas, have been the primary energy source since the Industrial Revolution. However, the combustion of these fuels has led to severe environmental and health issues, with air pollution and climate change posing significant dangers to children's health worldwide.
The combustion of fossil fuels is a major contributor to air pollution and greenhouse gas emissions, driving climate change. The average global temperature has risen by approximately 1.1°C since pre-industrial times due to fossil fuel emissions, and the consequences are already being felt, especially by children. Climate change and air pollution do not merely harm children's health; they also impact their entire lives and their potential as adults.
Children are particularly vulnerable to the effects of air pollution and climate change. Research has linked prenatal exposure to air pollution to altered brain structure, function, and metabolism in childhood. Air pollution has also been associated with respiratory illnesses in children, and it can increase the risk of preterm birth. The combustion of fossil fuels produces fine particulate matter, known as PM2.5, which includes soot and other pollutants. These particles are easily inhaled and can penetrate deep into the lungs, entering the bloodstream and causing damage to multiple organs.
The health impacts of air pollution from fossil fuel combustion are not limited to physical ailments. Studies have found associations between exposure to air pollution and symptoms of depression and anxiety in children as young as 12 years old. Furthermore, children from communities of color and low-income communities are disproportionately affected by the health consequences of fossil fuel pollution.
The combustion of fossil fuels is, therefore, the leading environmental threat to children's health. It contributes to climate change, deteriorates air quality, and poses risks to both the physical and mental well-being of children. Urgent action is required to limit global warming and mitigate the most severe consequences for the health of current and future generations.

Fossil fuel pollution kills more than HIV, tuberculosis and malaria combined
Fossil fuels are the main culprits behind the warming of the planet. The burning of fossil fuels releases nitrogen oxides into the atmosphere, contributing to the formation of smog and acid rain. This type of pollution has severe health impacts, with fine particulate matter (PM 2.5) from the burning of fossil fuels causing approximately 8.7 million deaths globally in 2018. To put this into perspective, this means that fossil fuel pollution kills more people annually than HIV, tuberculosis, and malaria combined.
PM 2.5 refers to any airborne particle that is up to 2.5 microns in diameter, or about one-thirtieth of the width of a human hair. These tiny particles are harmful because they remain in the air, are easily inhaled, and can penetrate deep into the lungs, where they can enter the bloodstream and damage multiple organs. The air we breathe affects everyone's health, especially children, the elderly, those on low incomes, and people of colour. People in urban areas are usually the most affected.
The combustion of fossil fuels also contributes to ozone air pollution and smog, which have been excluded from the estimated death toll. The highest number of deaths was in China and India, with nearly five million premature deaths in those two countries alone. Other severely affected areas include Western Europe, Southeast Asia, and parts of the US Northeast and Midwest.
The environmental impacts of fossil fuels extend beyond air pollution, also affecting water and land. Excess nitrogen in the atmosphere is deposited onto land and washes into nearby water bodies, contributing to pollution, harmful algal blooms, and oxygen-deprived aquatic zones. The ocean has become more acidic, threatening marine life. Climate change caused by carbon pollution leads to rising global temperatures, extreme weather events, wildfires, and rising sea levels.

Fossil fuel combustion releases nitrogen oxides, contributing to smog and acid rain
Fossil fuels, such as coal, oil, and natural gas, have been the primary energy source since the Industrial Revolution. However, the combustion of these fuels releases harmful substances into the atmosphere, contributing to air pollution and climate change. One of the significant pollutants released during fossil fuel combustion is nitrogen oxides (NOx).
Nitrogen oxides are a group of highly reactive gases that include nitrogen dioxide (NO2) and nitric oxide (NO). When fossil fuels are burned, they release nitrogen oxides into the atmosphere. This is particularly common in the transportation and industrial sectors, with vehicles and power plants being major sources of nitrogen oxide emissions.
Once emitted, nitrogen oxides can remain in the atmosphere for several days, reacting with other pollutants and contributing to the formation of smog. Smog is a type of air pollution characterized by a mixture of smoke, fog, and harmful chemicals, including nitrogen oxides. It reduces visibility and is harmful to human health, particularly in vulnerable populations such as children, the elderly, and individuals with respiratory conditions.
Additionally, nitrogen oxides are a key contributor to acid rain. When released into the atmosphere, they react with water, oxygen, and other substances to form airborne sulfuric and nitric acid. These acidic compounds can be carried by winds over long distances and eventually fall back to the Earth's surface as acid rain. Acid rain has detrimental effects on ecosystems, damaging forests, aquatic systems, and soil quality.
To combat the issues of smog and acid rain caused by nitrogen oxide emissions, it is essential to reduce the burning of fossil fuels. This can be achieved through various measures, such as transitioning to cleaner energy sources, improving energy efficiency, and implementing air-quality standards. By curbing the release of nitrogen oxides into the atmosphere, we can mitigate their harmful effects on the environment and human health.

Fossil fuel pollution disproportionately affects vulnerable communities
Fossil fuels are wreaking havoc on our environment, and the consequences are more severe than most people realize. The environmental impacts of fossil fuels extend far beyond air and water pollution. Climate change due to carbon pollution causes the planet's rising temperatures, extreme weather events, wildfires, and rising sea levels. The burning of fossil fuels releases nitrogen oxides into the atmosphere, contributing to the formation of smog and acid rain. Fossil fuels also produce hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury, all of which are harmful to the environment and human health.
The impacts of the fossil fuel industry on vulnerable communities are not limited to air pollution. Oil spills from fossil fuel extraction, transportation, and refining can destroy habitats, erode shorelines, and result in beach, park, and fishery closures. The 2010 BP Deepwater Horizon oil spill in the Gulf of Mexico, for example, released 134 million gallons of oil, killing 11 people and countless animals and plants. Additionally, mining and drilling for fossil fuels destroy animal habitats, and the increasing acidity of the oceans due to carbon pollution threatens marine life.
Communities that are economically dependent on fossil fuels are also vulnerable to socioeconomic and environmental stressors during the transition to clean energy. These communities may face problems with pollution, low education rates, and other environmental risk factors. It is important for policymakers to recognize these local circumstances and tailor their solutions accordingly to support these communities during the energy transition.

Fossil fuel combustion releases carbon dioxide, the main human-produced climate-altering gas
Fossil fuels like coal, oil, and natural gas contain carbon from millions of years of photosynthesis. When fossil fuels are burned, the stored carbon is released into the atmosphere as carbon dioxide, a greenhouse gas. Greenhouse gases like carbon dioxide absorb heat radiating from the Earth's surface and re-release it in all directions, including back toward the Earth's surface, amplifying the natural greenhouse effect and causing global temperatures to rise.
The burning of fossil fuels is the primary source of increased carbon dioxide in the atmosphere today. In 2024, humans emitted about 37.4 billion tons of carbon dioxide by burning fossil fuels, over 100 times more than the carbon dioxide emitted by volcanoes. Carbon dioxide levels today are higher than at any point in human history. The last time atmospheric carbon dioxide amounts were this high was roughly 3 million years ago during the Mid-Pliocene Warm Period, when global surface temperatures were 2.5–4 degrees Celsius warmer than during the pre-industrial era.
Since the Industrial Revolution, carbon dioxide emissions from burning fossil fuels have increased every decade. The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming. In 2018, 89% of global CO2 emissions came from fossil fuels and industry. Coal is the dirtiest fossil fuel, responsible for over 0.3 degrees Celsius of the 1-degree increase in global average temperatures. Oil releases a huge amount of carbon when burned, accounting for approximately one-third of the world's total carbon emissions. Natural gas accounts for a fifth of the world's total carbon emissions.
The combustion of fossil fuels also contributes to air pollution in the form of smog and acid rain. Fossil fuel pollution kills more people each year than HIV, tuberculosis, and malaria combined. It is estimated that there are 8.7 million premature deaths each year due to fossil fuel pollution. Burning fossil fuels releases nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain.
