Oil And Gas Pollution: Cancer Causers?

Air pollution is a pressing issue that poses a significant threat to human health and the environment. Among the various sources of air pollution, the oil and gas industry stands out as a major contributor. The extraction, production, and combustion processes within this sector result in the release of hazardous pollutants, including methane, benzene, formaldehyde, and acetaldehyde. These pollutants have far-reaching consequences, impacting air quality and raising serious concerns about their potential link to cancer. While the full extent of the health risks associated with oil and gas air pollution is yet to be quantified, initial findings suggest a heightened cancer risk for millions of people, particularly those residing in proximity to oil and gas sites. This issue demands urgent attention and comprehensive regulatory action to safeguard the well-being of communities affected by the toxic emissions from the oil and gas industry.

Oil and gas air pollution increases cancer risk in the US

Air pollution from the oil and gas industry is not only driving climate change by emitting methane but also putting millions of people in the US at increased risk of cancer. A recent report by the Clean Air Task Force (CATF) finds that nearly 14 million people in the US are being put at increased risk of cancer due to toxic air pollution emitted alongside methane at oil and gas sites.

The report, Fossil Fumes, analyzed the EPA's most recent Air Toxics Screening Assessment and estimated the cancer risk from oil and gas pollution. It found that in 33 counties, the cancer risk due to oil and gas pollution exceeds one in 250,000, and in three counties, the risk exceeds one in 100,000. The areas with the greatest health risks are generally located in states with significant oil and gas infrastructure, including Texas, North Dakota, Pennsylvania, Oklahoma, Louisiana, West Virginia, Colorado, and New Mexico.

The oil and gas industry emits a range of hazardous air pollutants, including methane, benzene, formaldehyde, and acetaldehyde. These pollutants can have serious health impacts, including an increased risk of cancer. For example, exposure to tiny particles from air pollution can lead to a build-up of these particles in the lungs, potentially damaging the DNA in lung cells and changing how cells divide, which can lead to cancer.

The good news is that the EPA is considering methane regulations that, coupled with methane provisions in the recently passed Inflation Reduction Act, could significantly improve air quality for communities living near oil and gas sites while reducing methane emissions. Additionally, readily available technologies and regulations can help reduce air pollution associated with leaking, venting, and flaring of natural gas throughout the oil and gas supply chain. Specific mitigation measures include replacing gas-driven pneumatic equipment with zero-emitting alternatives, requiring frequent leak detection and repair, eliminating venting from process equipment, and banning routine flaring and venting from oil wells. Implementing these measures would not only address climate change but also reduce the cancer risk for millions of people in the US.

Methane emissions from the oil and gas industry

Air pollution has been linked to an increased risk of lung cancer. While the relative risk of cancer from air pollution is small, it is still a concern, especially for those living near oil and gas sites. A recent report by the Clean Air Task Force (CATF) found that nearly 14 million people in the US are at an elevated risk of cancer due to the toxic air pollution emitted alongside methane at these sites. This is supported by another study, which found that in 33 counties, the cancer risk due to oil and gas pollution is alarmingly high, exceeding one in 250,000, and even surpassing one in 100,000 in three counties.

Methane, the primary component of natural gas, is a significant greenhouse gas, second only to carbon dioxide. The oil and gas industry is a major contributor to methane emissions, which have been found to be much higher than government predictions. Stanford-led research revealed that oil and gas operations in the US emit over 6 million tons of methane annually, resulting from both intentional vents and unintentional leaks. These emissions not only impact the climate but also carry a substantial economic cost, amounting to billions of dollars in losses for energy producers.

To address this issue, the EPA has proposed regulations and initiatives to curb methane emissions from the oil and gas sector. The EPA's Voluntary Methane Programs encourage oil and natural gas companies to adopt cost-effective technologies and practices that enhance operational efficiency while reducing methane emissions. Additionally, the EPA has committed to providing resources and assistance to various entities, including industry, state, local, and Tribal organizations, to promote methane emissions reduction.

Furthermore, the Inflation Reduction Act includes methane provisions that, when coupled with EPA's methane regulations, could significantly improve air quality for communities living near oil and gas sites. Strong regulations to reduce methane emissions from the oil and gas sector are crucial, and according to the CATF report, they would also support the creation of up to 220,000 high-quality jobs in the US.

While the focus is primarily on reducing emissions from new and existing sources, it is also important to recognize the potential benefits of capturing and utilizing methane. According to estimates, around 40% of methane emissions from fossil fuels could be avoided at no net cost, as the value of the additional methane gas captured and sold or used offsets the required outlays for abatement measures.

The impact of oil and gas air pollution on climate change

Oil and gas air pollution has been linked to an increased risk of cancer, particularly lung cancer. However, the impact of this type of air pollution on climate change is also significant.

The oil and gas industry is a major contributor to global air pollution, with leaks, flames, and excessive emissions from refineries releasing dangerous pollutants and toxicants that have severe environmental consequences. The production and use of oil and gas are closely linked to water, and the extraction and processing of these resources can contaminate water supplies and negatively impact natural resources. In addition, the drilling, processing, and transportation of oil and gas disturb the land, leading to pollution and damage to soils, vegetation, and water resources used for food production.

Oil and gas companies are facing growing pressure to reduce their environmental footprint and address the impact of their operations on climate change. The energy sector has been identified as having the most significant influence on climate change, and companies are being urged to move beyond mere decarbonization of their corporate footprints. To achieve this, oil and gas businesses should prioritize emission control in production areas and implement new technologies for sustainability and climate risk management.

The transition to clean energy is gaining momentum, yet oil and gas production in the United States is nearing record levels, causing concern among health experts about the implications for air quality and human health. A recent study found that air pollution from the oil and gas sector in the U.S. has detrimental effects on air quality, human health, and health costs. The pollutants nitrogen oxide, fine particulate matter (PM2.5), and ozone (O3) from oil and gas production have been linked to thousands of excess deaths, asthma attacks, and new cases of childhood asthma. These impacts are not limited to areas with significant oil and gas production but also extend to densely populated cities with little or no gas activity.

Addressing oil and gas air pollution is crucial for mitigating climate change and protecting human health. Reducing methane emissions from the oil and gas sector is identified as one of the fastest and most cost-effective ways to improve air quality and slow down climate change. Strong regulations and policies focused on emission reduction, such as the EPA methane regulations, are essential to achieving these goals and safeguarding communities from the health risks associated with oil and gas pollution.

The health effects of air pollution from the oil and gas sector

Air pollution from the oil and gas sector has been shown to have significant adverse effects on human health. The burning of fossil fuels is a leading cause of climate change and is hazardous to the health of communities near extraction, production, and consumption sites.

A Clean Air Task Force (CATF) report found that nearly 14 million people in the US are at an increased risk of cancer due to toxic air pollution emitted from oil and gas sites. In 33 counties, the cancer risk exceeds one in 250,000, and in three counties, it exceeds one in 100,000. The report also highlights the potential for strong regulations to reduce methane emissions, which would support up to 220,000 high-quality jobs in the US.

While the link between air pollution and cancer has been established, the specific mechanisms are still being studied. Research suggests that tiny particles from air pollution may build up in the lungs and damage the DNA of cells, altering their division process and leading to cancer. Additionally, these particles may cause inflammation in the lungs, which is another possible pathway to cancer development. It is important to note that the cancer risk from air pollution is relatively small compared to other factors, such as smoking.

To address these health concerns, strategies to reduce emissions from the oil and gas sector are crucial. This includes implementing regulations to curb methane, NO2, and other pollutant emissions. By doing so, we can improve air quality, protect public health, and mitigate the impacts of climate change.

Strategies to reduce air pollution from oil and gas production

Air pollution from oil and gas production has been linked to heightened cancer risks, with nearly 14 million people in the US being put at increased risk of cancer due to toxic air pollution emitted from oil and gas sites. This is especially true for people living in areas with significant oil and gas production, such as Texas, North Dakota, Pennsylvania, Oklahoma, Louisiana, West Virginia, Colorado, and New Mexico.

To reduce air pollution from oil and gas production and mitigate its harmful health effects, several strategies can be implemented:

• Strengthening and finalizing proposed rules and regulations: The US Environmental Protection Agency (EPA) has proposed revisions to its Clean Air Act rule to reduce methane and other harmful air pollutants from oil and natural gas operations. These regulations should be strengthened and finalized as soon as possible, building on successful state approaches in Colorado and New Mexico.
• Reducing methane emissions: Methane is a potent greenhouse gas, and the oil and natural gas industry is the largest industrial source of methane emissions. Strong regulations to reduce methane emissions from the oil and gas sector can not only support job creation but also significantly improve air quality and protect public health.
• Addressing precursor NO2 emissions: Strategies that focus on reducing NO2 emissions from the oil and gas sector can help mitigate childhood asthma cases in communities living near emission sources. NO2 is a major contributor to the formation of harmful PM2.5 and O3 particles, so reducing NO2 emissions can have significant health benefits.
• Implementing additional pollution control strategies: There are various technologies and strategies available to reduce methane leaks, emissions from compressor stations, and emissions from other sources, such as ponds and dehydrators.
• Transitioning away from fossil fuels: Ultimately, the only way to completely eliminate the health risks associated with oil and gas pollution is to stop permitting new drilling and begin transitioning to low-carbon energy sources and other climate-protecting technologies.

By implementing these strategies, significant improvements in air quality and public health can be achieved, while also addressing the impacts of climate change.
