Oil sands air pollution levels are 20-64 times higher than industry-reported figures
Oil sands are the fourth-largest oil deposit on Earth and are found in Alberta, Canada. They are among the most energy- and water-intensive to produce. Oil sands are a mixture of bitumen, a thick, heavy tar-like form of petroleum, and sand. The bitumen is extracted using both open-pit and in-situ mining, which involves pumping steam underground to liquify the bitumen. The oil sands industry in Canada consumes three barrels of fresh water for every one barrel of oil produced.
A recent Canadian government and Yale University study found that air pollution levels from oil sands operations are up to 64 times higher than industry-reported figures. The study used aircraft-based sensors to capture real-time readings for a much wider range of pollutants than those usually measured by the oil sands industry. The researchers found that the total amount of air pollution released from the oil sands is equal to all other human-caused air pollution sources in Canada combined.
The study identified hydrocarbon releases, including toxic volatile organic compounds (VOCs), intermediate volatility, and semi-volatile organic compounds (IVOCs/SVOCs) that can affect health. These compounds can react in the atmosphere, contributing to the formation of fine particulates harmful to health. Previous studies have also found that the oil sands industry releases numerous pollutants, including greenhouse gas emissions, secondary organic aerosols, and polycyclic aromatic compounds (PACs) into the watershed through air and water pathways.
The high levels of air pollution from oil sands operations have raised concerns among Indigenous communities living nearby, who worry about the potential health impacts. Traditional food sources, such as fish and ducks, are becoming increasingly scarce and polluted due to oil sands developments. Locals blame the oil sands for destroying the beauty of the region and impacting their cultural preference for food from the land.

The oil sands industry consumes three barrels of freshwater for every barrel of oil produced
Oil sands, also known as tar sands, are a mixture of sand, clay, water, and bitumen—a thick, heavy, tar-like form of petroleum used to make synthetic oil. Canada's oil sands are the fourth-largest oil deposit on Earth and one of the most energy-intensive to produce.
The oil sands industry in Canada consumes three barrels of freshwater for every barrel of oil produced. This has led to concerns about the impact on water sources and the environment. The Athabasca River in Alberta, Canada, for example, is an important water source that has been affected by the oil sands industry.
The process of extracting and refining oil from the oil sands requires a significant amount of water and energy. The water is used in open-pit mining to dig up shallow deposits and in situ mining, where hot water is pumped underground to liquify the bitumen. The large amount of water used in the process has raised concerns about the sustainability and environmental impact of the industry, particularly on water sources and ecosystems.
In addition to the high water consumption, the oil sands industry has been criticized for its environmental and health impacts. The extraction and production process emits a broad range of pollutants, including volatile organic compounds (VOCs) and intermediate and semi-volatile organic compounds (I/SOVs). These toxic compounds can affect human health and contribute to the formation of fine particulates that are harmful when inhaled.
The development of oil sands has also led to the destruction of natural habitats and disruption of traditional food sources for local communities, including Indigenous peoples in Canada. There are concerns about the pollution of water sources, with fish in some areas considered too contaminated for human consumption. The expansion of the oil sands industry and the construction of pipelines have faced opposition due to their potential environmental and health risks.

Oil sands extraction emits up to three times more global warming pollution than producing conventional crude
Oil sands extraction is a highly polluting process, with a particularly negative impact on the environment and local communities. A recent study found that air pollution levels from oil sands operations in Alberta, Canada, were up to 64 times higher than industry-reported figures, raising concerns about the potential health risks to nearby Indigenous communities.
The extraction process emits up to three times more global warming pollution than producing the same quantity of conventional crude oil. This is due to the energy-intensive nature of extracting and processing oil sands, which are thick, heavy, tar-like forms of petroleum mixed with sand, requiring vast open-pit mines or in-situ mining using hot water or steam to liquify the bitumen. The high water consumption of oil sands extraction also contributes to its environmental impact, with three barrels of fresh water consumed for every barrel of oil produced.
The pollution from oil sands extraction includes the emission of a broad range of pollutants, such as volatile organic compounds (VOCs) and intermediate and semi-volatile organic compounds (I/SOVs). These toxic compounds can affect human health and contribute to the formation of fine particulates harmful to health. The refining process produces hazardous by-products, such as petroleum coke, and the risk of spills and leaks during transportation further adds to the environmental risks.
The development of oil sands has had a significant impact on the local environment and communities in Alberta, with traditional food sources becoming polluted and scarce, and the degradation of nearly two million acres of boreal forest. The expansion of the industry, including the construction of pipelines like Keystone XL, has been met with opposition from environmental groups and Indigenous communities, who highlight the potential for increased pollution and the threat to water sources and wildlife ecosystems.

Oil sands are the fourth-largest oil deposit on Earth and among the most energy-intensive to access
Oil sands are a mixture of sand and clay, water, and a kind of oil called bitumen, which is too thick to flow on its own. Bitumen is a heavy and viscous form of petroleum that coats subsurface sand. The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of oil sands rich in bitumen, located in northeastern Alberta, Canada. These reserves are one of the largest sources of unconventional oil in the world, making Canada a significant player in the global energy market.
Canada's oil sands are the fourth-largest oil deposit on Earth, with about 161 billion barrels of estimated reserves. They are so large that Canada ranks third behind Venezuela and Saudi Arabia in terms of oil reserves. The oil sands are a significant part of Canada's oil production, with about 58% of all production coming from the oil sands in 2023.
The extraction of oil sands can have a significant impact on the environment. It can affect the land when the bitumen is initially mined, water resources due to its requirement for large quantities of water during the separation of oil and sand, and the air due to the release of carbon dioxide and other emissions. Heavy metals such as vanadium, nickel, lead, cobalt, mercury, chromium, cadmium, arsenic, selenium, copper, manganese, iron, and zinc are naturally present in oil sands and may be concentrated during the extraction process.
Oil sands production is among the most energy- and water-intensive in the world. Producers use vast open-pit mines to dig up shallower deposits, while deeper deposits are exploited in situ by pumping hot water underground to liquefy the tar-like bitumen. Both methods result in the emission of a much broader range of pollutants than previously thought. A recent study found that air pollution levels from oil sands operations are up to 64 times higher than reported by the industry.
The environmental impact of oil sand extraction has been frequently criticized by environmental groups and Indigenous communities living near the oil sands. There are concerns about the health impacts of the pollution, the destruction of the landscape, and the contamination of water sources. While oil sands producers have made efforts to reduce their environmental impact, such as recycling water and developing new technologies, the overall volume of tailings and the area of disturbed land continue to grow.

Oil sands operations impact the health and environment of local Indigenous communities
Oil sands operations in Alberta, Canada, have had a significant impact on the health and environment of local Indigenous communities. The region is home to the world's third-largest oil reserves, and the extraction process is highly polluting and energy-intensive. The mines have destroyed vast areas of boreal forest and wetlands, and the Indigenous community of Fort McKay is situated in the middle of them. Traditional food sources have become scarce and polluted, and locals blame oil sands developments. Fish caught in the area are considered too contaminated for human consumption, and a recent study found that 87% of Indigenous residents believe that oil sands development has contaminated the Peace and Athabasca Rivers, as well as the fish within them.
The oil sands industry also consumes large amounts of water, using three barrels of fresh water for every barrel of oil produced. This has led to concerns about water pollution, especially after a tailings water leak from Imperial Oil in 2024. This incident heightened pollution concerns and prompted the Canadian government to fund an Indigenous-led health study to examine the impacts of oil sands development on local communities. The study will cost C$12 million over 10 years and may include an assessment of cancer risks for communities downstream of the oil sands region, as communities have reported higher rates of cancer, autoimmune diseases, skin irritations, and severe arthritis.
In addition to the environmental and health impacts, the expansion of the oil sands industry has also threatened the cultural and economic practices of Indigenous communities. Locals have expressed concerns about the destruction of traditional hunting and trapping grounds, as well as the loss of cultural preferences for food sourced from the land. Furthermore, the oil sands industry has a complex history with Indigenous communities, dating back to the drafting of treaties in the late 19th century, which opened access to petroleum and other minerals on Indigenous lands.
While some companies claim to work closely with Indigenous communities and partner with them in energy development, local communities often have little choice in approving proposed oil sands projects. The influence of the oil industry on the government means that projects are almost always approved, regardless of community objections. This has led to a sense of powerlessness among Indigenous people, who feel that their existence is challenged by the industry, even as it provides jobs and revenue to Native businesses and communities.
Overall, the oil sands operations in Alberta, Canada, have had profound impacts on the health, environment, and cultural practices of local Indigenous communities. The recent government-funded health study aims to address these concerns and hold the federal and provincial governments and companies accountable for implementing stronger environmental and health measures.
