The Obama administration's latest efficiency standards for new cars and trucks are expected to dramatically curb America's oil consumption over the next decade. So does that mean the United States won't need to import so much oil from Canada's tar sands region?
Oil experts with two environmental groups say the answer to that question is yes.
"The federal [efficiency] standards are one more nail in the tar sands coffin," said Michael Marx, who directs the Sierra Club's Beyond Oil campaign. He said other "nails" include increased production of U.S. shale oil, accelerated development of electric-vehicle batteries, and existing and proposed rules in California, Oregon and Washington that would slash global warming emissions in transportation fuels.
Luke Tonachel, senior vehicles analyst for the Natural Resources Defense Council (NRDC), said the new rules "show that America can avoid the costly impacts of importing high-carbon oil derived from Canadian tar sands."
But other energy experts interviewed by InsideClimate News say that despite our reduced oil needs, Canadian imports will continue rising and the Canada-to-Texas Keystone XL pipeline will still be needed.
Kenneth Medlock, a fellow in energy and resource economics at Rice University's Baker Institute in Houston, said that even as Americans make fewer stops at the gas pump, "there's still going to be upward pressure" on the global price of oil, making tar sands oil profitable for producers.
All of that crude will likely end up in the United States, Medlock said, due largely to the nation's proximity to Canada and to U.S. ambitions to use only North American energy sources.
The new rules, known as the Corporate Average Fuel Economy (CAFE) standards, are expected to reduce U.S. oil consumption by more than 2 million barrels a day by 2025. That's about the same amount of crude oil the U.S. imports from all Canadian suppliers today. By 2030, those savings could ratchet up to 3.1 million barrels a day, or roughly one-third of the nation's current total imports.
The rules require automakers to get an average fleet efficiency of 54.5 miles per gallon within 13 years, or nearly double the efficiency of today's cars.
Despite the savings the rules will create, Medlock said the United States will still need to import oil to meet its transportation needs. But the new standards could enable the country to reduce its imports from Middle Eastern and African nations and get a larger percentage from Canada and other North American suppliers. "It just shifts our focus" in terms of where our imports come from, he said of the CAFE rules.
Currently, more than one million barrels of crude from Canada's oil sands region flow to U.S. refineries each day, up from just a trickle in the early 2000s. Producers hope to quadruple that amount in the next decade.
Tom Kloza, chief oil analyst at Oil Price Information Service in New Jersey, predicted that, due to rising Canadian and U.S. oil production and the fuel standards, "in the second half of this decade, we're going to be North America and Venezuela sufficient."
According to federal energy projections, which don't take into account the latest CAFE standards, while Canadian crude oil imports are rising, imports from nearly every other part of the world are expected to decline, with total imports falling from just under 9 million barrels a day this year to 7.27 million barrels a day by 2025.
Tar Sands Imports Rise, But Face Hurdles
For decades, crude from Canada's oil sands region was considered too expensive to exploit. But as lighter, sweeter crude oil has become more scarce and more expensive—and as extraction methods have improved—major oil companies are finding it increasingly worthwhile to extract the bitumen.
Tar sands production consumes more energy than pumping conventional oil up from a well, adding significantly to operating expenses. It requires extracting a thick mixture of sand, clay and bitumen—the oil's core ingredient—from deep beneath Alberta's boreal forests, usually by strip-mining or boiling it loose underground. The bitumen, which has the consistency of peanut butter, is then mixed with liquid chemicals so it can flow through pipelines.
Greenhouse gas emissions from Canadian tar sands production are about 82 percent higher than the average crude refined in the United States, according to estimates by the U.S. Environmental Protection Agency.
Despite the explosive growth of the tar sands industry, producers still face two major challenges, both of which are already depressing prices—and profits—for their products.
The first is the unexpected increase in U.S. oil production from the North Dakota and Texas shale formations, due largely to the use of a controversial drilling technique called hydraulic fracturing. Fracking, as it's known, involves pumping millions of gallons of water, sand and chemicals at high pressure into horizontal wells to open shale rock and free oil and natural gas.
