What You'll Learn
Natural gas is a fossil fuel
Natural gas is often marketed as a clean form of energy, but it contributes to climate change and pollutes the air and water. The combustion of natural gas for energy has a high carbon footprint. According to the EIA, in 2020, the total carbon footprint of gas in the United States was almost twice that of coal (1,647 million metric tons of CO2 from gas consumption versus 875 million metric tons from coal). Natural gas production and use accounted for about one-fifth of human greenhouse gas emissions in 2020, and this contribution is growing rapidly.
Natural gas infrastructure has a history of explosions and leaks, which can have devastating consequences for the environment and human health. For example, the 2015 Aliso Canyon gas leak near Los Angeles released over 95,000 tons of methane into the atmosphere, placing more than 35,000 people at risk.
The extraction and consumption of natural gas can also result in air and water pollution. Well drilling and the laying of pipelines can disturb vegetation, soil, and water resources. Natural gas production can generate large volumes of contaminated water, which requires proper handling and treatment to prevent water pollution. Engines used to run equipment and compressors at well sites and pipelines produce air pollutants and noise.
Fracking, a technique used to extract natural gas, involves pumping liquids under high pressure into wells to fracture rock formations and release natural gas. This process requires large amounts of water, which can impact aquatic habitats and water availability for other uses.

Natural gas contributes to climate change
Natural gas is a fossil fuel and a major contributor to climate change. It is often marketed as a clean form of energy, but this is misleading. The use of fossil fuels for energy contributes to a number of environmental problems, and natural gas is no exception.
Natural gas emits pollution, including methane, carbon dioxide, nitrogen oxides, and volatile organic compounds (VOCs). These pollutants are released during the extraction, transportation, and combustion of natural gas. Methane is the main component of natural gas, and it is a much more potent greenhouse gas than carbon dioxide, trapping much more heat in the atmosphere. Leaks of methane from natural gas infrastructure, such as valves and pipes, are a significant source of emissions. In addition to methane leaks, the combustion of natural gas for energy releases carbon dioxide and other harmful pollutants into the atmosphere.
The production and use of natural gas also have indirect effects on the environment. Well drilling and pipeline construction can disturb vegetation, soil, and water resources. Natural gas production can generate large volumes of contaminated water, which can pollute land and water bodies if not properly handled. The use of natural gas appliances at home can create indoor air pollution, with gas stoves and ovens releasing unsafe levels of nitrogen dioxide and other toxic chemicals linked to illnesses such as asthma and cancer.
Furthermore, the infrastructure associated with natural gas has a history of explosions and leaks, which can have devastating consequences for human health and the environment. Reducing methane emissions from the natural gas industry and transitioning to cleaner energy sources are critical steps in mitigating climate change. While natural gas may emit fewer pollutants than other fossil fuels, it is still a significant contributor to climate change and environmental degradation.

Natural gas leaks during extraction
Natural gas is a fossil fuel that emits pollution and contributes to climate change. It is often marketed as a clean form of energy, but this is misleading. Natural gas leaks during extraction and transportation are common and have significant negative impacts on the environment and human health.
Natural gas extraction involves drilling wells and pipelines, which can disturb vegetation, soil, and water resources. The drilling process produces air pollution and can impact people, wildlife, and water sources. One of the main issues with natural gas extraction is the potential for leaks, which can release methane and other harmful gases into the atmosphere. Methane is a potent greenhouse gas that can accelerate climate change. According to studies, a significant percentage of methane produced in the US leak during mining, storage, and transportation.
In one study of 21,525 wells, it was found that more than 10% had leaked at some point, with natural gas seeping into the air. While most of these leaks were small, some wells released up to 300 times more gas, contributing heavily to the total volume of leaked methane. These leaks can have both local and global impacts. For example, the 2015 Aliso Canyon gas leak in California released over 95,000 tons of methane, affecting the health and safety of nearby residents and contributing to climate change.
The volatile organic compounds (VOCs) found in natural gas can cause dizziness, headaches, and respiratory issues for people living nearby. Benzene, a chemical found in natural gas, has been detected in groundwater in some communities, posing a risk to those who drink it. Diesel fumes from trucks and machinery operating at extraction sites can also pose a hazard to workers and residents.
To address these issues, natural gas operators can utilize tools such as the TDL-500 Portable Laser Diode Methane Detector to pinpoint leaks and repair faulty equipment. However, there is ongoing debate and controversy among policymakers and scientists about the true extent of methane leaks during natural gas extraction. Some argue that stricter regulations and more detailed measurements are needed to fully understand and mitigate the impact of these leaks.

Natural gas pollutes air and water
Natural gas is a fossil fuel that emits pollution and contributes to climate change. It is often marketed as a clean form of energy, but this is misleading. Natural gas pollutes the air and water in several ways and has adverse effects on human health and the environment.
Firstly, natural gas contributes to air pollution through its production and use. During well drilling and extraction, natural gas can be released into the atmosphere, along with other harmful air pollutants. The combustion of natural gas releases methane, a potent greenhouse gas that traps heat in the atmosphere, contributing to global warming. Methane leaks from natural gas infrastructure, such as valves and pipes, are also common, leading to significant methane emissions. These leaks can have a substantial impact on climate change, as methane is 28 to 100 times more warming than carbon dioxide over shorter periods.
Additionally, natural gas infrastructure, such as compressor stations, processing facilities, and pipelines, has been responsible for explosions, posing risks to workers and nearby residents. The use of gas appliances, such as stoves and ovens, can create indoor air pollution, releasing nitrogen dioxide and other toxic chemicals linked to asthma and cancer. According to a study, gas stoves were associated with almost 13% of childhood asthma cases in the United States.
Moreover, natural gas production can generate large volumes of contaminated water. This wastewater can pollute land and water bodies if not properly handled, stored, and treated. Naturally occurring radioactive materials can accumulate in wastewater pipes, exposing maintenance workers to higher levels of radiation.
The extraction process can also disturb vegetation, soil, and wildlife habitats. Drilling activities and the construction of pipelines require clearing and leveling land, impacting local ecosystems and water resources. The high water consumption associated with hydraulic fracturing (fracking) can further affect aquatic habitats and water availability for other uses.
In summary, natural gas pollutes air and water through its production, infrastructure, and use. It contributes to greenhouse gas emissions, indoor air pollution, water contamination, and disturbances to natural habitats. While natural gas may emit fewer pollutants compared to other fossil fuels, it is still a significant contributor to climate change and has detrimental effects on human health and the environment.
