Fossil fuels cause climate change, leading to extreme weather events
The combustion of fossil fuels releases large amounts of greenhouse gases, especially carbon dioxide (CO2), into the atmosphere. These gases trap heat, leading to global warming and climate change. The Intergovernmental Panel on Climate Change (IPCC) has confirmed that emissions from fossil fuels are the dominant cause of global warming. In 2018, 89% of global CO2 emissions were from fossil fuels and industry. Oil, for instance, releases a significant amount of carbon when burned, accounting for approximately one-third of total carbon emissions worldwide. Natural gas, though promoted as a cleaner energy source, is still a fossil fuel that contributes to a fifth of the world's total carbon emissions.
Climate change, caused by the burning of fossil fuels, is contributing to more frequent and severe extreme weather events. These include wildfires, hurricanes, wind storms, flooding, and droughts, which have resulted in disasters costing billions of dollars. For instance, the cost of extreme weather events in the United States between 2016 and 2020 was estimated at $606.9 billion. The increase in average global temperatures has also led to rising sea levels, with oceans having risen about 9 inches since the late 1800s. This, in turn, has caused more frequent flooding, destructive storm surges, and saltwater intrusion, impacting the 40% of the US population living along the coasts.
The impacts of climate change are far-reaching and affect the rights of millions of people. Climate change can lead to the loss of homes, restricted access to clean water, and health issues related to extreme temperatures. It disproportionately affects marginalized and discriminated communities, with people in countries that have contributed the least suffering the worst consequences. Additionally, climate change and the associated changes in ocean conditions can have indirect impacts on deep-sea life.
Fossil fuel combustion is the leading cause of environmental threats to global paediatric health and equity. The developing fetus and young children are more vulnerable to the adverse effects of toxic air pollutants and climate change due to their rapid growth and immature detoxification and immune systems. Exposure to air pollutants during early development can impair brain development and increase the risk of respiratory and cardiovascular illnesses later in life. Climate change can also contribute to malnutrition, which stunts children's bodies and brains, resulting in impaired cognitive functioning and learning abilities.
Furthermore, the production and use of fossil fuels are closely linked to plastic pollution. Over 99% of plastics are made from fossil fuels, and the industry's greenhouse gas emissions are projected to surpass those of coal-fired power plants by 2030. Plastic waste, ending up in oceans, kills wildlife and pollutes the food chain. It also releases toxic pollutants that increase health risks, particularly in marginalized communities living near factories.

They release toxic air pollutants, causing health issues, especially in children
The combustion of fossil fuels releases toxic air pollutants, which have been linked to a range of adverse health effects, particularly in children. Fossil fuel combustion is the primary source of air pollution, emitting hazardous pollutants such as sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants have severe consequences for both the environment and human health.
Children are especially vulnerable to the toxic air pollutants released from fossil fuel combustion due to their developing and immature physiological systems. The prenatal period and early childhood are critical stages, as the fetus and young child have immature detoxification, immune, and thermoregulatory systems. Their rapid growth and dynamic developmental programming make them more susceptible to the toxic effects of air pollution.
The health impacts of air pollution from fossil fuels on children are extensive. It has been associated with respiratory illnesses, cognitive and behavioural impairments, and other chronic diseases. Exposure to air pollutants during early brain development can impair children's ability to learn and affect their future economic productivity and contributions to society. The impacts of air pollution can also extend beyond the individual, as communities with unhealthy children become less resilient and equitable.
The combustion of fossil fuels has been linked to an increased risk of childhood diseases such as asthma. Additionally, climate change, largely driven by fossil fuel emissions, exacerbates these health issues. The combination of air pollution and climate change can magnify the harm to children, affecting their physical and mental health, both immediately and over their lifetime.
The adverse effects of fossil fuel combustion disproportionately impact children from low-income communities and communities of colour. These communities are often located near industrial areas or pollution sources, increasing their exposure to toxic air pollutants. Social and economic disadvantages further compound the health risks faced by these vulnerable populations.

Extraction and transportation lead to oil spills, which harm ecosystems and communities
The extraction and transportation of fossil fuels can have detrimental effects on ecosystems and communities. Oil spills, a frequent occurrence in the fossil fuel industry, are a prime example of these adverse consequences.
Oil spills often result from accidents at oil wells, pipelines, ships, trains, or trucks involved in transporting oil from wells to refineries. These spills contaminate soil and water, leading to devastating explosions and fires. The environmental impact of oil spills is significant, with long-lasting damage to marine ecosystems and wildlife. For instance, the 2010 BP Deepwater Horizon spill in the Gulf of Mexico killed approximately one million seabirds, five thousand marine mammals, and a thousand sea turtles, spreading oil across 68,000 square miles of sea surface. Smaller spills during extraction, such as leaks and splashes of drilling fluids, can also be dangerous and have devastating effects on local wildlife through direct contact, inhalation, and ingestion of toxic chemicals.
Extraction and transportation activities can also disturb land and marine ecosystems. Exploration and drilling for oil may require clearing vegetation and the use of seismic techniques that can harm fish and marine mammals. The infrastructure built for extraction, such as power lines, well pads, fences, and roads, can fragment habitats for many species. Additionally, the loud noises, human movement, and vehicle traffic associated with drilling operations can disrupt animal communication, breeding, and nesting.
Communities are also directly impacted by oil spills, which can contaminate drinking water sources and destroy the biodiversity and means of subsistence for those living nearby. The toxic waste generated by fossil fuel extraction and transportation can cause health issues such as nausea, headaches, breathing difficulties, stinging eyes, and burning skin. These health impacts can affect both workers and neighbouring communities. Furthermore, the pollution and environmental damage caused by oil spills can hurt local economies that depend on tourism and outdoor recreation.
The adverse effects of oil spills extend beyond the immediate ecological and community impacts. The cleanup costs and penalties associated with major spills can be significant, as evidenced by the $65 billion cost to BP for the Deepwater Horizon spill. Additionally, oil spills contribute to climate change, which exacerbates extreme weather events and disproportionately affects marginalized communities that may struggle to adapt to changing conditions.

Fossil fuels are the primary source of plastic production, causing plastic pollution
Fossil fuels are the primary source of plastic production, which is a major contributor to climate change and plastic pollution. Over 99% of plastics are made from fossil fuels, and the production of these plastics can be incredibly harmful to the health of communities living near factories. The combustion of fossil fuels releases greenhouse gases, such as carbon dioxide, which contribute to climate change and have been linked to 1.2 million deaths in 2020 alone.
Plastic production is a significant driver of climate change, emitting four times more greenhouse gases than the airline industry. The US plastic industry produces 232 million tons of carbon dioxide equivalent per year, and its greenhouse gas emissions are expected to surpass those of coal-fired power plants by 2030. Global plastic production is projected to increase, with investments potentially expanding production capacity by a third. This will lead to even higher emissions and a greater contribution to climate change.
The production and use of plastics have severe environmental consequences. Approximately 300 million tons of plastic waste are produced globally each year, with 14 million tons ending up in the ocean. Plastic waste kills wildlife, pollutes the food chain, and breaks down into microplastics that infiltrate waterways and even our bloodstream. Burning plastic releases harmful emissions, while burying it contributes to leachate formation, which contaminates soil and groundwater.
The close connection between the fossil fuel and plastic industries underscores the need to address plastic production and pollution in climate change mitigation policies. Reducing reliance on plastics, especially single-use plastics and unnecessary packaging, is crucial. The global plastics treaty negotiations, which began in 2022, present an opportunity to implement mandatory measures to curb plastic production, eliminate toxic chemicals, and address the plastic crisis.
The adverse effects of plastic pollution, driven by fossil fuel-based plastic production, highlight the urgency of transitioning away from fossil fuels and towards more sustainable alternatives.

They emit greenhouse gases, contributing to global warming and ocean warming
The combustion of fossil fuels releases greenhouse gases, such as carbon dioxide (CO2), into the atmosphere. These gases have heat-trapping properties, contributing to the greenhouse effect and global warming. This phenomenon has led to significant climate change, impacting various aspects of the environment and human health.
Global warming, driven by the emission of greenhouse gases from fossil fuels, has resulted in ocean warming. This has caused the oceans to absorb a substantial portion of the excess heat, leading to rising ocean temperatures. The consequences of ocean warming are far-reaching and detrimental to marine ecosystems and the planet as a whole.
Ocean warming has led to the melting of glaciers and land-based ice sheets, contributing to the ongoing rise in sea levels. This, in turn, has increased the frequency of coastal flooding, destructive storm surges, and saltwater intrusion, impacting communities and ecosystems along coastlines. The rise in ocean temperatures also affects marine life, including fish, marine mammals, and plants, disrupting their habitats and biodiversity.
Additionally, the absorption of excess carbon dioxide by the oceans leads to ocean acidification. This process alters the chemistry of the seawater, decreasing the pH level. Ocean acidification can have far-reaching consequences for marine life, affecting the survival and behaviour of various species, including fish, marine mammals, and shellfish. It can also impact the calcification process of some marine organisms, affecting their ability to build and maintain their skeletons and shells.
The adverse effects of fossil fuels on the environment and human health have been widely recognised. The combustion of fossil fuels releases hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, volatile organic compounds, and toxic metals such as mercury. These pollutants contribute to air pollution, smog formation, and the deterioration of air quality, leading to respiratory and cardiovascular illnesses. Fossil fuel extraction and transportation also carry the risk of irreversible oil spills, which devastate marine ecosystems, contaminate drinking water sources, and destroy the livelihoods of communities dependent on marine resources.
