Fuels That Cause The Most Environmental Harm

The combustion of fossil fuels is the leading cause of environmental threats to global pediatric health and equity. Fossil fuels are the primary source of energy for producing electricity and powering vehicles. The burning of these fuels releases a myriad of toxic air pollutants and carbon dioxide (CO2), which is the most critical human-produced climate-altering greenhouse gas. Carbon monoxide is the gas that causes the maximum amount of air pollution. The health and economic costs of the impacts of fossil-fuel combustion by-products are significant, with an estimated 50,000 to 120,000 premature deaths associated with exposure to air pollutants.

Fossil fuels and climate change

Fossil fuels are formed from the decomposition of carbon-based organisms that died millions of years ago. They are extracted and burned for energy, and they are the dominant cause of global warming. Fossil fuels include coal, oil, and natural gas, which are burned to produce electricity and power vehicles. This combustion releases a myriad of toxic air pollutants and carbon dioxide (CO2), which is the most important human-produced climate-altering greenhouse gas.

The combustion of fossil fuels has severe impacts on the environment and human health, especially children's health. It contributes to climate change, leading to rising temperatures, sea levels, and ocean acidification. Climate change also poses risks to species survival, with one million species at risk of extinction within decades. It further affects water availability, making it scarcer in many regions and increasing the risk of agricultural and ecological droughts.

The effects of fossil fuel combustion on human health are significant. It impairs cognitive and behavioral development, contributes to respiratory illnesses, and causes other chronic diseases. These impacts can begin in utero and affect individuals throughout their lives, reducing their ability to learn and contribute to society. Fossil fuel emissions disproportionately harm low-income communities and communities of color, widening health and economic inequalities.

To address these issues, a transition to renewable energy sources is necessary. While green energy sources may have higher upfront costs, they do not incur the external costs associated with fossil fuels, such as environmental damage and public health issues. Additionally, they can provide economic benefits, such as increased energy self-sufficiency and job creation in rural communities.

It is important to note that emissions from fossil fuels continue to rise. According to the Global Carbon Budget 2023, emissions from fossil fuels rose by 1.1% in 2023 compared to 2022 levels, reaching 36.8 billion metric tons of carbon dioxide. This trend underscores the urgency of reducing our reliance on fossil fuels and transitioning to cleaner energy alternatives.

Carbon dioxide and carbon monoxide

Carbon dioxide (CO2) is a naturally occurring gas that is essential for plant and animal life. It is produced through natural processes such as respiration and volcanic activity, but it is also a byproduct of human activities, particularly the burning of fossil fuels like coal, oil, and natural gas. CO2 is a greenhouse gas, which means it traps heat in the Earth's atmosphere, leading to the greenhouse effect. While it is necessary for maintaining Earth's temperature, excessive CO2 emissions from human activities have intensified the greenhouse effect, causing global warming and climate change. The combustion of fossil fuels releases a range of toxic air pollutants, including carbon dioxide, which poses significant risks to human health and the environment.

Carbon monoxide (CO), on the other hand, is a byproduct of incomplete combustion during the burning of carbon-containing fuels, such as natural gas, gasoline, or wood. It is a colorless, odorless, and tasteless gas that can be harmful when inhaled in large amounts. CO is released from vehicles, trucks, and other machinery that burn fossil fuels. Additionally, indoor sources of CO, such as gas stoves, malfunctioning heating systems, and fires, can affect air quality and lead to serious health issues. Carbon monoxide poisoning occurs when it builds up in the bloodstream, replacing oxygen in red blood cells and causing tissue damage.

While carbon dioxide is a significant contributor to global warming and climate change, carbon monoxide has a more indirect impact. CO participates in chemical reactions in the atmosphere, contributing to the production of ground-level ozone, which is harmful to both human health and vegetation. However, carbon monoxide is not considered a significant greenhouse gas, and its direct contribution to global warming is relatively minor compared to carbon dioxide.

Both carbon dioxide and carbon monoxide have significant impacts on pollution and human health. Carbon dioxide, as a greenhouse gas, drives climate change and global warming, leading to environmental and societal consequences. Carbon monoxide, while not a major driver of climate change, poses immediate health risks due to its toxic nature and ability to reduce oxygen transport in the bloodstream.

Addressing carbon dioxide and carbon monoxide pollution requires a multifaceted approach. Transitioning to green and renewable energy sources can reduce reliance on fossil fuels, thereby decreasing carbon dioxide emissions and improving air quality. Additionally, implementing measures to reduce vehicle emissions and improve indoor ventilation can help mitigate carbon monoxide levels, protecting human health and minimizing its indirect contribution to climate change.

Health impacts on children

The burning of fossil fuels, including coal, oil, natural gas, and gasoline, is a major source of air pollution and greenhouse gas emissions, driving climate change. This has severe health implications for children, who are particularly vulnerable to the toxic air pollutants and climate change impacts resulting from fossil fuel combustion.

Children, especially those from low-income communities and communities of colour, bear a disproportionate burden of disease and developmental impairment due to environmental pollution and climate change. The combustion of fossil fuels releases a range of toxic particles and gases, including carbon dioxide (CO2), a significant driver of climate change and a good indicator of the amount of fossil fuel burned and the resulting pollutant emissions. Other harmful pollutants released include fine particulate matter (PM), black carbon, polycyclic aromatic hydrocarbons (PAHs), mercury, nitrogen dioxide, sulfur dioxide, and carbon monoxide. These pollutants have been linked to numerous adverse health effects on children.

The health impacts of air pollution and climate change on children are wide-ranging and significant. They include respiratory illnesses, cognitive and behavioural developmental impairments, and other chronic diseases. These issues may be "seeded" in utero, affecting children's health, ability to learn, and potential to contribute to society even before birth. The fetus, infant, and child are all vulnerable to exposure to air pollution and climate change, with potential physical and mental health consequences. Poor children are at an even higher risk of suffering from the health impacts of fossil fuel pollution due to their increased exposure to environmental pollution and climate change.

The World Health Organization (WHO) has reported that air pollution is the leading environmental health risk globally. In 2012, approximately 3.7 million deaths were attributed to ambient air pollution, and 4.3 million deaths were linked to household air pollution from solid fuel use for cooking and heating. Children are the subgroup of the population most affected by air pollution and will benefit the most from policies aimed at reducing fossil fuel emissions in the coming decades.

Addressing the health impacts of fossil fuel pollution on children requires a holistic, child-centred energy and climate policy that considers the full range of physical and psychosocial stressors resulting from air pollution and climate change. Additionally, interventions such as tobacco bans in schools, smoking counselling for parents, and awareness campaigns can help reduce children's exposure to secondhand smoke and improve their overall health.

Economic impact of pollution

The burning of fossil fuels, such as coal, oil, natural gas, and gasoline, is a major contributor to air pollution and climate change. Carbon monoxide, produced from the burning of fossil fuels, is the gas that causes the maximum amount of air pollution. The economic impact of this pollution is significant, with costs incurred in the healthcare and environmental sectors.

A study found that in the United States, air pollution exposure from fossil fuels costs each American around $2,500 in additional medical bills. This figure rises to $7.9 billion annually when fossil fuel emissions are combined with higher temperatures, leading to increased ozone pollution and worsened asthma and cardiovascular issues. The economic impact of air pollution is not limited to healthcare costs. Acid rain, a result of air pollution, causes $6 billion in damage annually to crops, forests, lakes, and buildings.

The impact of air pollution falls disproportionately on the young, the poor, and certain minorities, especially in developing countries. These communities are more vulnerable to the health and economic consequences of toxic air pollutants and CO2-driven climate change. The total economic impact of air pollution is substantial, with estimates suggesting that it accounts for a notable percentage of the GDP in some regions. For instance, in the states of Uttar Pradesh and Bihar, India, the economic loss due to air pollution as a percentage of their GDP was among the highest in the country.

However, transitioning to cleaner technologies and reducing greenhouse gas emissions can bring significant economic benefits. For example, a study by the World Resources Institute (WRI) projected that reducing U.S. greenhouse gas emissions by 80% by 2050 would require an investment of $320 billion annually from 2020 to 2050. This investment would yield extensive benefits, including a reduction in annual fossil fuel costs, the creation of nearly one million additional jobs, and the development of green industries.

Furthermore, some countries have demonstrated that it is possible to decouple economic growth from air pollution emissions. This means that they can maintain economic health without compromising the environment. This trend is observed in some high-GDP countries in North America and Europe, where fossil fuel emissions are decreasing even as economies grow.

Green energy and electricity

Fossil fuels are the world's most significant threat to children's health and future, and major contributors to global inequality and environmental injustice. The combustion of fossil fuels releases a myriad of toxic air pollutants, including carbon dioxide, nitrogen dioxide, and carbon monoxide, which is the gas that causes the maximum amount of air pollution. Fossil fuels are also the largest contributor to global climate change, accounting for over 75% of global greenhouse gas emissions and nearly 90% of carbon dioxide emissions.

Green energy is energy produced from natural sources that cause no harm to the environment. Examples of green energy sources include the sun, wind, moving water, organic plant and waste material, and the earth's heat. Green energy sources are renewable, meaning they are constantly and naturally replenished, and emit little to no greenhouse gases or pollutants into the air.

Green electricity is electricity produced from green energy sources. Within the US voluntary market, green power is defined as electricity produced from solar, wind, geothermal, biogas, eligible biomass, and low-impact small hydroelectric sources. Green electricity has zero emissions and reduces the carbon footprint, helping to mitigate climate change.

The use of green energy and electricity offers several benefits. Firstly, it increases energy self-sufficiency and economic security by reducing reliance on fossil fuel imports. Secondly, it helps to reduce the rapid depletion of natural resources and creates jobs and income, particularly in rural communities. Additionally, green energy sources are often more affordable than traditional fossil fuel-based generation, and their prices are dropping rapidly.
