Fossil Fuels: Major Air Polluters And Climate Change Drivers

Fossil fuels are a major source of air pollution, which has a significant impact on the environment and public health. The combustion of fossil fuels, such as coal, oil, and natural gas, releases harmful pollutants into the atmosphere, including carbon dioxide, nitrogen oxides, sulfur dioxide, and particulate matter. These emissions contribute to climate change, poor air quality, and a range of health issues, particularly in vulnerable communities. With rising global temperatures and increasing environmental concerns, addressing the impact of fossil fuels on air pollution is crucial for a sustainable future.

Fossil fuels emit harmful air pollutants even before they're burned

Fossil fuels are formed from the decomposition of carbon-based organisms that died and were buried millions of years ago. They are non-renewable and currently supply around 80% of the world's energy. They are used to generate electricity, power transportation, and for industrial processes.

The burning of fossil fuels releases large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in the atmosphere, causing global warming and climate change. Fossil fuel emissions have led to rising sea levels, extreme weather events, biodiversity loss, species extinction, food scarcity, and worsening health for millions worldwide.

However, fossil fuels emit harmful air pollutants even before they are burned. Mining, drilling, and fracking operations generate toxic waste and release pollutants into the air and water. For example, coal mining washes toxic runoff into water sources and dumps unwanted rock and soil into streams. Oil spills during extraction or transport can also pollute drinking water sources and devastate entire ecosystems.

Fracking, a controversial extraction method, involves blasting a mixture of water, chemicals, and sand into wells to fracture rock and release oil or gas. This process has been linked to air and water pollution, as the toxic fluids can contaminate drinking water sources. Additionally, all drilling, fracking, and mining operations produce enormous volumes of wastewater, which can be laden with heavy metals, radioactive materials, and other pollutants that can leak into waterways.

According to a 2017 study, approximately 17.6 million Americans are exposed daily to toxic air pollution from active oil and gas wells, as well as transport and processing facilities. These pollutants include benzene, linked to childhood leukemia and blood disorders, and formaldehyde, a known carcinogen. The booming fracking industry is expected to bring these pollution levels closer to populated areas, despite evidence of its detrimental health impacts.

Overall, the fossil fuel industry's extraction and refinement processes contribute significantly to air pollution, even before the fuels are burned. These emissions have severe environmental and health consequences, underscoring the urgent need for a transition to clean and renewable energy sources.

Burning fossil fuels releases carbon dioxide, a greenhouse gas

Burning fossil fuels is a major contributor to air pollution. Fossil fuels are carbon-rich deposits formed from the decomposition of buried carbon-based organisms that died millions of years ago. These fossil fuels, such as coal, oil, and natural gas, are extracted and burned for energy, generating electricity and powering transportation and industrial processes.

The burning of these fuels releases carbon dioxide (CO2), a greenhouse gas, into the atmosphere. Greenhouse gases, including carbon dioxide and nitrous oxide, trap heat in the Earth's atmosphere, leading to global warming and climate change. The average global temperature has already increased by 1°C, and the critical 1.5°C milestone was surpassed in 2024. This warming has far-reaching consequences, including the risk of sea level rise, extreme weather events, biodiversity loss, species extinction, food scarcity, and worsening health and poverty for millions worldwide.

Carbon dioxide emissions from fossil fuels have significant environmental and health impacts. They contribute to air pollution, releasing hazardous pollutants such as sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants reduce air quality, causing respiratory diseases and other health issues. Poor air quality disproportionately affects vulnerable communities, including children, the poor, and minority groups, exacerbating environmental injustice and health inequalities.

In addition to air pollution, burning fossil fuels also impacts water sources. The extraction and transportation of fossil fuels can lead to oil spills, contaminating drinking water and jeopardizing aquatic ecosystems. Furthermore, the cooling systems of power plants that burn fossil fuels can stress local species by removing and returning warm freshwater to nearby ecosystems.

To address the environmental and health consequences of burning fossil fuels, a transition to renewable and clean energy sources is necessary. Reducing carbon dioxide emissions and mitigating climate change are crucial for protecting both the planet and the health and well-being of current and future generations.

Fossil fuels are the leading cause of air pollution-related deaths

Fossil fuels are a leading cause of air pollution and related deaths. The burning of fossil fuels releases large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases, such as carbon dioxide and nitrous oxide, trap heat in the Earth's atmosphere, causing global warming and climate change. The combustion of fossil fuels emits hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants reduce air quality and have harmful impacts on both the environment and human health.

The health effects of air pollution from fossil fuels are significant and far-reaching. Poor air quality caused by fossil fuel emissions can lead to respiratory diseases, asthma, cancer, heart disease, and other chronic conditions. Fossil fuel combustion products are particularly detrimental to children's health, impairing cognitive and behavioral development and increasing the risk of respiratory illnesses. The impacts of air pollution on children can begin as early as in utero and persist throughout their lives. Fossil fuel air pollution disproportionately affects vulnerable communities, including low-income areas, communities of color, and developing countries, exacerbating environmental injustice.

In addition to the direct health impacts, fossil fuel air pollution contributes to climate change, which further endangers human health and the environment. The warming effect caused by greenhouse gas emissions leads to rising global temperatures, altered ecosystems, and extreme weather events. The combustion of fossil fuels is the primary driver of current climate change, and the increasing temperatures risk sea level rise, biodiversity loss, species extinction, food scarcity, and worsening health for millions worldwide.

According to a recent Environmental Research study, fossil fuel air pollution is responsible for an estimated 8.7 million premature deaths each year. This figure does not even include deaths caused by long-term exposure to ozone air pollution or smog, which are also driven by fossil fuel combustion. The highest toll of fossil fuel air pollution deaths was observed in China and India, totaling nearly five million premature deaths in those two countries alone. Other severely affected regions include Western Europe, Southeast Asia, and parts of the United States Northeast and Midwest.

To address the issue of fossil fuel air pollution and its deadly consequences, a transition to renewable energy sources and improved energy efficiency is imperative. While natural gas is often promoted as a cleaner alternative to coal and oil, it is still a fossil fuel that contributes significantly to carbon emissions and global warming. Therefore, a comprehensive shift away from fossil fuels is necessary to mitigate the health and environmental impacts of air pollution caused by these fuels.

Fossil fuel combustion disproportionately impacts low-income communities and minorities

Fossil fuels are formed from the decomposition of buried carbon-based organisms that died millions of years ago. They are extracted through mining, drilling, and fracking, and are burned for energy. The burning of fossil fuels releases large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.

The combustion of fossil fuels also releases soot and smog, which are harmful to human health. A recent study by Harvard University, the University of Birmingham, and the University of Leicester estimated that air pollution from fossil fuels causes 8.7 million premature deaths each year. The study also noted that this figure does not include deaths caused by long-term exposure to ozone air pollution or smog, which are also driven by fossil fuel combustion.

The impacts of fossil fuel combustion are not evenly distributed, and low-income communities and minorities are disproportionately affected. A 2023 peer-reviewed study by Greenpeace found that fossil fuels impose unfair and unjust health harms on Black, Brown, Indigenous, and poor communities. These communities are also hit hardest by the impacts of the climate crisis, such as extreme weather events and sea-level rise. The study identified the public health harms and disproportionate impacts at each stage of the fossil fuel lifecycle, including extraction, processing, transport, and combustion.

Another report by Greenpeace reviewed the disproportionate impacts of toxic pollution from petroleum refineries and petrochemical facilities on Black, Brown, and poor communities. It was found that these communities already have an elevated burden of exposure to air pollutants that can harm the respiratory system, known as PM2.5. This pattern is consistent across almost all emission source types.

The fossil fuel industry has been accused of contributing to systemic racism by externalizing the costs of pollution and environmental degradation onto communities of color. "Fossil fuel racism" is a term used to describe how the fossil fuel industry actively protects and promotes continued production, even in the face of public health and environmental concerns.

To address these disparities, some have called for a managed phase-out of fossil fuel production and the enactment of wider social, economic, and democratic reforms. A Green New Deal has been proposed as a way to halt climate change, build a more just and regenerative economy, and protect democratic spaces.

Fossil fuel companies are huge polluters, despite advertising clean energy

Fossil fuel companies are responsible for a significant amount of air pollution, yet they continue to advertise clean energy and low-carbon solutions. Despite their claims, these companies are still heavily invested in oil and gas, with little expenditure on renewable energy sources. This advertising strategy is a form of greenwashing, where companies deflect responsibility for climate change onto consumers and mislead the public about their environmental impact.

In 2019, BP spent millions on an advertising campaign promoting its low-carbon energy and cleaner natural gas. However, over 96% of BP's annual expenditure is still allocated to oil and gas. BP is not the only company engaging in this practice, with Shell, Chevron, and ExxonMobil also identified as high-emitting investor-owned companies. These fossil fuel giants have stepped back from their climate pledges and net-zero commitments, choosing instead to focus on exploration and expansion.

The impact of burning fossil fuels on air quality is significant. When fossil fuels are burned, they release large amounts of carbon dioxide and other harmful pollutants into the atmosphere. This contributes to global warming and climate change, with average global temperatures already increased by 1°C. Fine particulate matter (PM 2.5) produced by burning coal, gasoline, and diesel has been linked to an estimated 8.7 million premature deaths each year.

Fossil fuel companies are also responsible for environmental pollution beyond air quality. The extraction and transportation of fossil fuels can result in oil spills and leaks, contaminating drinking water sources and damaging ecosystems. Fracking, a controversial method of extraction, creates air and water pollution and generates enormous volumes of wastewater laden with toxic chemicals and pollutants.

Despite the growing number of legal cases and initiatives to ban fossil fuel ads and hold companies accountable for misleading marketing, fossil fuel advertising continues to shape public discourse about climate change. It is crucial that consumers are educated about sustainability and can identify greenwashing, as many companies are reinvesting in fossil fuel development and expansion rather than transitioning to clean energy.
