The oil sands or tar sands, are a mixture of sand, water, clay and a type of oil called bitumen. to developing the oil sands and improving environmental performance. impacts on air, land and water, and provide benefits for our country.
4 Apr 2017 Recent government studies of a different tar sands pipeline have found footprint in a series of Keystone XL environmental impact statements. 10 Aug 2010 From the air, the oil-bearing tar sands mines of northern Alberta, the refinery did not need to submit a full environmental impact statement. 16 Oct 2019 A secondary extraction plant at the Suncor Fort Hills oil-sands extraction site near Fort are producing oil “with a smaller greenhouse impact than the oil average. Environmental activists have pushed a growing number of Facilities used to upgrade tar sand oil would pose potential primary impacts of of Potential Primary Environmental Impacts— Surface Mining of Tar Sands 21 6 Extracting oil from U.S. public lands through oil shale or tar sands would deal a oil shale program without sufficiently addressing environmental impacts.
11 Apr 2019 As a result of these issues, oil from the oil sands has a higher environmental cost than other sources, Belanger says. “I grew up in the bush up

Since development began around 40 years ago, 84,000 square kilometres of land underlain with oil sands deposits has been leased in Alberta, accounting for about 60% of the total resource area. 8 Lands are leased to companies with no environmental impact assessments or consultation with stakeholders (including Aboriginal groups). This part of the process does not take place until the project application phase of development.
Oil sands (e.g., tar sands oil, crude bitumen), unlike crude oil, is a comparatively “dirty” fuel. From an environmental perspective, there is ample evidence that pipeline spills, leaks, and ruptures releasing diluted bitumen can have serious implications for the surrounding land and water. Tar Sands require an average of three barrels of water to produce one barrel of oil. Most of this water comes from the Athabasca River, which has had its average summer flow decline 29% between 1970 and 2005. Only 5-10% of water taken from the river is returned to it, as it is too toxic. Because the bitumen from tar sands can be converted into crude oil through its processing, it can fit into our existing energy infrastructure quite easily. This helps to keep costs down and doesn’t require any changes to societal infrastructures to use the energy resource. Study No. 143. The development of the Canadian Oil Sands has a considerable and growing impact on the the environment. This report is an overview of the current environmental impacts of oil sands development and progress and efforts that have been made to mitigate impacts. Technological advancements in the oil sands have helped create more energy efficient practices and to decrease GHG emissions in the oil sands. One of the most important mechanisms used to achieve this is co-generation. This is a process where steam and electricity is produced simultaneously. By converting energy and by-product into electricity that would otherwise be waste, co-generation has contributed significantly to the 30% decrease in per barrel GHG emissions seen in the oil sands since A Plan to Unlock Billions of Barrels of Oil From Utah’s Sands. Backers say their method will avoid the environmental toll incurred in Canada’s oil sands — some others aren’t so sure — and will yield profits at half the current price of crude.
Tar sands represent a potentially vast reserve of oil [2] but come with their own environmental challenges. Oil production from tar sands uses large amounts of land (for open-pit mining), water, and energy, when compared to other oil resources. Open-pit mining also produces a lot of waste (leftover sand, clays,
11 May 2007 Cursed by Oil? Institutions and Environmental Impacts in Alberta's Tar Sands. Presented by Angela V. Carter, PhD Candidate. Government 17 Sep 2018 Through the responsible development of its oil sands, Canada continues to play and reduce environmental impacts at our oil sands facilities. Environmental impacts of oil sands The environmental impact of the oil sands is an issue that has been extremely divisive. As with the extraction and use of any fossil fuel , negative environmental effects arise as a result of the extraction, upgrading , and processing of bitumen from the oil sands.
21 Feb 2020 Video of Learn about the environmental impact of tar-sand (also called oil-sand) extraction, with a focus on Canada.
