Why Canadian Tar Sands are the Most Environmentally Destructive Project on Earth
[Editor's note: Today, scientists and advocates speaking at the National Press Club in Washington unveiled new research showing that the Keystone XL tar sands pipeline would damage the climate much more than previously thought, by dramatically expanding tar sands production and because it will lead to increased combustion of a particularly dirty form of oil. Two reports were presented today, including Petroleum Coke: The Coal Hiding in the Tar Sands revealing that current analyses of the impacts of tar sands fail to account for a high-carbon byproduct of the refining process that is a major source of climate change causing carbon emissions: petroleum coke—known as petcoke, and The Climate Implications of the Proposed Keystone XL Oilsands Pipeline from the Pembina Institute—a Canadian environmental think tank—revealing how the Keystone XL tar sands pipeline would accelerate expansion of the tar sands and significantly increase greenhouse gas emissions.
Energy and Commerce Committee Ranking Member Henry A. Waxman issued the following statement on these two reports: “The new reports show that TransCanada’s Keystone XL pipeline is the key that will unlock the tar sands. If the pipeline is approved, the world will face millions more tons of carbon pollution each year for decades to come. After Hurricane Sandy, devastating drought, unprecedented wildfires and the warmest year on record in the United States, we know that climate change is happening now, we have to fight it now, and we must say no to this pollution pipeline now.”]
The Canadian tar sands have been called the “most environmentally destructive project on earth,” with good reason.
But what if we told you that a significant proportion of the climate impact from exploiting the tar sands has been overlooked?
That’s the story told in our latest report Petroleum Coke: the Coal Hiding in the Tar Sands.
It turns out that analysts have been examining the liquid fuels derived from tar sands bitumen and calculating the emissions associated with producing those light liquid fuels (i.e. gasoline and diesel), and adding the emissions from burning those liquid fuels to derive a “well-to-wheels” analysis of emissions.
On this basis alone, the European Commission has determined that the emissions from tar sands derived fuel are 23 percent greater than fuel from conventional crude used in Europe.
But tar sands bitumen is a semi-solid hydrocarbon. In fact a barrel of bitumen contains 24 percent more carbon than a barrel of conventional light oil. This additional carbon does not make its way through to the gasoline and diesel manufactured from tar sands bitumen. It is removed.
This "removed" carbon doesn’t disappear; far from it. In fact 15 to 30 percent of a barrel of tar sands bitumen is converted during the refining process into a coal-like solid fuel called petroleum coke or "petcoke." This is considered a byproduct of tar sands refining and most analysts assessing the climate impact of the tar sands have to date dismissed the emissions from burning this petcoke.
They have done this partly because they have not developed a methodology to include petcoke emissions into their calculations of the emissions from the liquid fuels. Some have recognized it’s there and have raised it as an issue for further study.
But industry analysts including IHS CERA, which has published two studies on tar sands greenhouse gas emissions entitled Getting the Numbers Right, consider the emissions from burning petcoke as “negligible.” The assumption is that petcoke simply replaces coal and therefore there is no net emissions rise.
This is a convenient but entirely misguided assumption.
Petcoke is like coal, but is in fact dirtier. Petcoke has even higher carbon emissions than already carbon-intensive coal, emitting between 5 to 10 percent more CO2 than coal per unit of energy produced. A ton of petcoke yields on average 53.6 percent more CO2 than a ton of coal.
So even if petcoke did simply replace coal, which is not the case, the net emissions from whichever activity the petcoke is fueling (eg: power generation) are higher.
But because petcoke is a byproduct refineries price it “to move.” It is selling into the market at around a 25 percent discount to coal.
Now we all know (don’t we?) the basic law of economics. More Supply = Lower Prices = More Demand. But growing supplies of petcoke are not only adding to the global supply of fuel for coal-fired power generators, they are undercutting coal on price.
Indeed industry analysts have shown that a typical 1 gigawatt coal plant can save around $120 million per year in fuel costs by blending petcoke with coal in their boilers. That sounds to us like a boon for coal-fired generators and a bad deal for cleaner fuels competing with coal in a tight market.
Our report reveals the following startling facts about the tar sands and petcoke.
- Petcoke in the tar sands is turning American refineries into coal factories.
- There is 24 percent more CO2 embedded in a barrel of tar sands bitumen than in a barrel of light oil.
- 15 to 30 percent of a barrel of tar sands bitumen can end up as petcoke depending on the upgrading and refining process used.
- Of 134 operating U.S. refineries in 2012, 59 are equipped to produce petcoke.
- U.S. refineries produced more than 61.5 million tons of petcoke in 2011—enough to fuel 50 average U.S. coal plants each year.
- In 2011, more than 60 percent of U.S petcoke production was exported.
- Keystone XL will fuel five coal plants and thus emit 13 percent more CO2 than the U.S. State Department has previously considered.
- Nine of the refineries close to the southern terminus of Keystone XL have nearly 30 percent of U.S. petcoke production capacity, over 50,000 tons a day.
- The petcoke produced from the Keystone XL pipeline would fuel 5 coal plants and produce 16.6 million metric tons of CO2 each year.
- These petcoke emissions have been excluded from State Department emissions estimates for the Keystone XL pipeline. Including these emissions raises the total annual emissions of the pipeline by 13 percent above the State Department’s calculations.
- Cheap petcoke helps the coal industry.
- As a refinery byproduct, petcoke is “priced to move,” selling at roughly a 25 percent discount to conventional coal.
- Rising petcoke production associated with tar sands and heavy oil production is helping to make coal fired power generation dirtier and cheaper—globally.
- From January 2011 to September 2012, the U.S. exported more than 8.6 million tons of petcoke to China, most of which was likely burnt in coal-fired power plants.
- “PetKoch”: The largest global petcoke trader in the world is Florida based Oxbow Corporation, owned by William Koch—the brother of Charles and David Koch.
- Oxbow Carbon has donated $4.25 million to GOP Super PAC s, making it the one of the largest corporate donors to super PACs.
- Oxbow also spent over $1.3 million on lobbyists in 2012.
As mentioned above, the impacts of petcoke on the local and global environment have not been considered by regulatory bodies in assessing the impacts of the tar sands.
Petcoke’s full impacts must be considered by the European Union in its debate on the Fuel Quality Directive, by the U.S. State Department in its consideration of the climate impacts of the Keystone XL pipeline, and by Canadian, American and European governments in tar sands policies across the board.
Increasing petcoke use is a clear result of the increasing production of tar sands bitumen. Petcoke is a seldom discussed yet highly important aspect of the full impacts of tar sands production. Factored into the equation, petcoke puts another strong nail in the coffin of any rational argument for the further exploitation of the tar sands.

Cabin fever is often associated with being cooped up on a rainy weekend or stuck inside during a winter blizzard.
In reality, though, it can actually occur anytime you feel isolated or disconnected from the outside world.
What is cabin fever?<p>In popular expressions, cabin fever is used to explain feeling bored or listless because you've been stuck inside for a few hours or days. But that's not the reality of the symptoms.</p><p>Instead, cabin fever is a series of negative emotions and distressing sensations people may face if they're isolated or feeling cut off from the world.</p><p>These feelings of isolation and loneliness are more likely in times of <a href="https://www.healthline.com/health-news/yes-covid-19-cases-are-rising-why-you-still-need-to-practice-social-distancing" target="_blank">social distancing</a>, self-quarantining during a <a href="https://www.healthline.com/health/what-is-a-pandemic" target="_blank">pandemic</a>, or sheltering in place because of severe weather.</p><p>Indeed, cabin fever can lead to a series of symptoms that can be difficult to manage without proper coping techniques.</p><p>Cabin fever isn't a recognized psychological disorder, but that doesn't mean the feelings aren't real. The distress is very real. It can make fulfilling the requirements of everyday life difficult.</p>
What are the symptoms?<p>Symptoms of cabin fever go far beyond feeling bored or "stuck" at home. They're rooted in an intense feeling of isolation and may include:</p><ul><li>restlessness</li><li>decreased motivation</li><li><a href="https://www.healthline.com/health/irritability" target="_blank">irritability</a></li><li>hopelessness</li><li><a href="https://www.healthline.com/health/unable-to-concentrate" target="_blank">difficulty concentrating</a></li><li><a href="https://www.healthline.com/health/irregular-sleep-wake-syndrome" target="_blank">irregular sleep patterns</a>, including sleepiness or sleeplessness</li><li>difficulty waking up</li><li><a href="https://www.healthline.com/health/lethargy" target="_blank">lethargy</a></li><li>distrust of people around you</li><li>lack of patience</li><li>persistent <a href="https://www.healthline.com/health/depression/depression-vs-sadness" target="_blank">sadness or depression<br></a></li></ul>
What can help you cope with cabin fever?<p>Because cabin fever isn't a recognized psychological condition, there's no standard "treatment." However, mental health professionals do recognize that the symptoms are very real.</p><p>The coping mechanism that works best for you will have a lot to do with your personal situation and the reason you're secluded in the first place.</p><p>Finding meaningful ways to engage your brain and occupy your time can help alleviate the distress and irritability that cabin fever brings.</p><p>The following ideas are a good place to start.</p>
When to get help<p>Cabin fever is often a fleeting feeling. You may feel irritable or frustrated for a few hours, but having a virtual chat with a friend or finding a task to distract your mind may help erase the frustrations you felt earlier.</p><p>Sometimes, however, the feelings may grow stronger, and no coping mechanisms may be able to successfully help you eliminate your feelings of isolation, sadness, or depression.</p><p>What's more, if your time indoors is prolonged by outside forces, like weather or extended shelter-in-place orders from your local government, feelings of <a href="https://www.healthline.com/health/anxiety" target="_blank">anxiety</a> and fear are valid.</p><p>In fact, anxiety may be at the root of some cabin fever symptoms. This may make symptoms worse.</p><p>If you feel that your symptoms are getting worse, consider reaching out to a mental health professional who can help you understand what you're experiencing. Together, you can identify ways to overcome the feelings and anxiety.</p><p>Of course, if you're in isolation or practicing social distancing, you'll need to look for alternative means for seeing a mental health expert.</p><p>Telehealth options may be available to connect you with your therapist if you already have one. If you don't, reach out to your doctor for recommendations about mental health specialists who can connect with you online.</p><p>If you don't want to talk to a therapist, <a href="https://www.healthline.com/health/depression/top-iphone-android-apps" target="_blank">smartphone apps for depression</a> may provide a complementary option for addressing your cabin fever symptoms.</p>
The bottom line<p>Isolation isn't a natural state for many people. We are, for the most part, social animals. We enjoy each other's company. That's what can make staying at home for extended periods of time difficult.</p><p>However, whether you're sheltering at home to avoid dangerous weather conditions or heeding the guidelines to help minimize the spread of a disease, staying at home is often an important thing we must do for ourselves and our communities.</p><p>If and when it's necessary, finding ways to engage your brain and occupy your time may help bat back cabin fever and the feelings of isolation and restlessness that often accompany it.</p>
