The spending and tax policy agreement Congress and the White House have reached to keep the government funded and running includes important wins for health and the environment.

But there’s good news to report, only because of the Herculean efforts of House Minority Leader Nancy Pelosi, D-San Francisco, Senate Minority Leader Harry Reid, D-Nev., and the White House, who worked tirelessly to block nearly all of the dozens and dozens of proposals Republican leaders were pushing.

Those proposals would have blocked action on climate, clean air, clean water, land preservation and wildlife protection and stripped key programs of needed resources. The Republican leaders’ proposals were the clearest expression yet of their “just say no” approach to environmental policy. They literally have no plan, except to block every movement forward on problems that threaten our health and our planet.

The worst aspect of the budget agreement is another clear indication of Republican leaders’ misplaced priorities — they exacted an end to the decades-long ban on sending U.S. crude oil overseas in this bill, in return for giving up on key elements of their antienvironment agenda.

Senate Majority Leader Mitch McConnell, R-Ky., made that give-away to the oil industry one of his top priorities. It will mean increased oil drilling in the U.S., with all the attendant dangers, with the benefits going to oil companies and overseas purchasers. That won’t help the American public, or the climate. It’s simply an undeserved gift to Big Oil.

In good news, the agreement extends tax credits for wind and solar energy for five years, which will give those industries long-sought certainty about their financing.

Wind and solar will continue to grow by leaps and bounds, helping domestic industry, reducing carbon pollution and making the U.S. less vulnerable to the ups and downs of fossil fuel prices.

Democratic leaders deserve all our thanks for what they were able to keep out of the budget deal. Gone are the vast majority of obstacles Republican leaders tried to throw in the way of environmental protection. Recall for a moment the 100 or more antienvironmental provisions Republican leaders tried to attach to these spending bills. Those included efforts to:

• Block the Environmental Protection Agency’s Clean Power Plan, which sets the first-ever limits on carbon pollution from power plants — our best available tool to combat dangerous climate change.

• Roll back the Obama Administration’s Clean Water Rule, which would restore protections for the potential drinking water supplies of 1 in 3 Americans.

• Repeal the EPA’s newly issued health standards to protect us from smog.

• Bar the Interior Department from protecting our streams from the pollution generated by mountaintop removal during coal mining.

• Strip Endangered Species Act protections for gray wolves, the greater sage grouse, elephants, the Sonoran Desert tortoise, and other threatened animals.

• Force approval of the proposed Keystone XL tar sands oil pipeline, which President Obama already has rejected.

There’s more work ahead to protect the environment, starting with eliminating the threat of oil drilling in the Arctic and off the Atlantic Coast.

But despite the efforts of Republican congressional leaders to hold the public hostage and bring us to the brink of another government shutdown, a budget deal has emerged that protects environmental progress.

Why cheap oil is the key to beating climate change

Why cheap oil is the key to beating climate change

Keeping the price of a barrel of crude at $75 or less will devastate the profitability of fossil fuel extraction – as the shelving of three tar sands projects demonstrates

As world leaders enter the home stretch of the Paris climate negotiations they should keep in mind a key measure of success in limiting carbon emissions: cheap oil. The lower the global price of oil, the more it stays in the ground – due to the brutal, if counterintuitive, logic of the petroleum marketplace.

Most of the easily extracted oil deposits are long gone. What’s left are high-cost, high-risk long shots such as the Alberta tar sandsdeep-water reservoirs off Brazil, and drilling the high Arctic. Companies hoping to profit from the last dregs of the petroleum age need to convince their investors to part with massive amounts of capital in hopes of competitive returns often decades down the road.

Billions have already fled the Alberta oil sands in the last year as the global price of oil collapsed from over $100 per barrel to below $40. Shell has just called a halt to its Carmon Creek project in Northern Alberta, writing off $2bn in booked assets and 418 million barrels of bitumen reserves. A barrel of bitumen will release about 480kg of carbon dioxide from extraction, refining, transport and combustion. This head office write-down means that 200m tonnes of carbon will not be released into the atmosphere.

Two other tar sands projects were also shelved this year with reserves of about 3bn barrels. If these investments stay dead the world will avoid another 1.6tn tonnes of dangerous carbon emissions. Together the cancellation of these three projects alone amount to the equivalent of taking more than 14m cars off the road for the next 25 years.

There a simple correlation between future emissions and the price of oil needed to make that profitable. Such a graph has been compiled by Carbon Tracker, a UK-based non-profit organisation set up to educate institutional investors on the increasing financial risks of the fossil fuel sector.

Its message to investors is simple: the world must limit additional emissions to below 900 gigatons to avoid potentially catastrophic climate consequences – and 40% of this future carbon budget – about 360 gigatons – is projected to come from the oil sector. Anything more than that must stay in the ground – the so-called unburnable carbon.

And what’s the price of oil that could save to world? Anything below $75 a barrel of Brent crude means that companies cannot profitably extract more than 360 gigatons of the world’s remaining reserves – no messy policy solutions required.

Just last year the price of Brent crude was about $110 a barrel, a price that would gainfully produce about 500 gigatons of carbon emissions by 2050. Now it is less than $50, which would only produce 180 gigatons over the same period. If prices stay where they are, the world will avoid some 320bn tonnes of carbon emissions by 2050 in precluded production from uneconomic oil fields.

To put this in perspective, that is 25 times larger than reductions the Kyoto protocol was supposed to achieve if it had worked (it didn’t), and 180 gigatons below the oil emissions limit scientists say we need to avoid a world with more than two degrees of warming. Economic turmoil aside, the global commodities market just served up massive progress on an issue in desperate need of some good news.

Carbon Tracker recently revised its calculations to include the turmoil in the oil market, but the basic correlation is the same: lower fossil fuel prices devastate the economics of future extraction.

Seen through this lens, a key measure of our success in controlling carbon emissions should be keeping commodity prices of fossil fuels low. And while the main driver of the current slump in prices is the current glut of supply, it’s important to realise that almost every policy intervention to avert climate disaster is directly or indirectly aimed at lowering the price or profitability of fossil fuels such as oil and coal.

Efficiency and conservation incentives reduce demand, as do vehicle emission standards and investing in public transit. Carbon pricing means that fossil fuel companies can no longer use the atmosphere as a free dumping ground for CO2, so also lowering profitability.

But doesn’t cheap gas mean that people just use more of it? Not really. While there is a weak economic link between declining prices and increasing consumption, key producers like Saudi Arabia are in fact fretting that slowing growth in Asian markets and already peaked demand in developed countries will lead to a long-term decline in the world’s appetite for oil.

I dearly hope that world leaders can somehow negotiate transformative change. But perhaps the best they can do is nudge economic indicators like crude prices in the right direction and get out of the way. The unstoppable forces of the global marketplace will hopefully do the rest.

U.S. Not Prepared for Tar Sands Oil Spills, National Study Finds

U.S. Not Prepared for Tar Sands Oil Spills, National Study Finds

Report urges new regulations, research, and technology to respond to spills of diluted bitumen.

Spills of heavy crude oil from western Canada’s tar sands are more difficult to clean up than other types of conventional oil, particularly if the spill occurs in water, a new study by a high-level committee of experts found. Moreover, current regulations governing emergency response plans for oil spills in the United States are inadequate to address spills of tar sands oil.

The study by the U.S. National Academies of Sciences, Engineering, and Medicine confirmed what scientists, emergency responders, and conservationists knew anecdotally from a major oil spill that contaminated Michigan’s Kalamazoo River in 2010 and another spill in Mayflower, Arkansas in 2013. Tar sands crude, called diluted bitumen, becomes denser and stickier than other types of oil after it spills from a pipeline, sinking to the bottom of rivers, lakes, and estuaries and coating vegetation instead of floating on top of the water.


“[Diluted bitumen] weathers to a denser material, and it’s stickier, and that’s a problem. It’s a distinct problem that makes it different from other crude.”

–Diane McKnight, Chair 
Committee on the Effects of Diluted Bitumen on the Environment


“The long-term risk associated with the weathered bitumen is the potential for that [oil] becoming submerged and sinking into water bodies where it gets into the sediments,” Diane McKnight, chair of the committee that produced the study and a professor of engineering at the University of Colorado Boulder, told Circle of Blue. “And then those sediments can become resuspended and move further downstream and have consequences not only at the ecosystem level but also in terms of water supply.”
“It weathers to a denser material, and it’s stickier, and that’s a problem. It’s a distinct problem that makes it different from other crude.” McKnight added. Weathering is what happens after oil is spilled and exposed to sunlight, water, and other elements. In order to flow through pipelines, tar sands crude oil is mixed with lighter oils, which evaporate during the weathering process. In a matter of days, what is left of the diluted bitumen can sink.

The study’s findings come amid an expansion in unconventional fuels development and transport in North America. Over the past decade, Canada became the world’s fifth largest crude oil producer by developing the Alberta tar sands. U.S. imports of Canadian crude, much of it from tar sands, increased 58 percent over the past decade, according to the U.S. Energy Information Administration.

Though oil prices are at a seven-year low, and market turbulence is expected to persist for several more years, tar sands developers are working to double the current tar sands oil production — around 2.2 million barrels per day — by 2030. Pipelines to transport all of the new oil are expanding too, producing a greater risk of spills.

Whether tar sands producers achieve that level of oil supply is not assured. Public pressure is mounting in Canada and the United States to rein in tar sands development due to considerable environmental damage and heavy carbon emissions. U.S. President Barack Obama last month scrapped the Keystone XL pipeline, an 800,000-barrel-per-day project to move crude oil from Canada’s tar sands to Gulf of Mexico refineries. An international movement to divest from fossil fuels and a legally binding global deal to cut carbon emissions –if it is signed in Paris– could curb demand for tar sands oil.

The National Academies of Sciences, Engineering, and Medicine study adds new data to arguments made by critics of tar sands development.

“The study really confirms a lot of the information that has been out there, there are no real surprises,” Jim Murphy, senior counsel for the National Wildlife Federation, told Circle of Blue. “You don’t want these things to be affirmed because it’s bad news for communities. But the good part about a study like this is hopefully it will prompt some action. Some folks were hiding behind the lack of a study like this, saying we don’t really know. Those excuses have gone away.”

“The chief takeaway is that this is a different oil, it presents different challenges, and responders and regulators simply don’t have the structures in place to deal with the challenges,” he added.

Nonetheless, energy companies are pursuing pipeline expansions, most notably in the Midwest and Great Lakes regions. Enbridge, Canada’s largest transporter of crude oil, operates a 3,000-kilometer (1,900-mile) pipeline network, known as the Lakehead System, that carries crude oil from Canada to refineries on the Great Lakes. The Lakehead system, in concert with Enbridge’s Canadian main line, is capable of transporting 2.62 million barrels of oil per day. The pipeline responsible for the 2010 oil spill in Kalamazoo was part of the Lakehead system. A link in the Lakehead system ruptured in 2010 and spilled more than 3 million liters (843,000 gallons) of tar sands oil into southern Michigan’s Kalamazoo River. It was the largest inland oil spill in U.S. history and its effects still linger because of oil that sank and is embedded in the river’s sediments.

Enbridge is currently pursuing upgrades to its Alberta Clipper pipeline, which runs through Minnesota and Wisconsin, in order to boost the line’s capacity to 800,000 barrels per day from 450,000 barrels per day. A second project aims to increase the capacity of Line 61, a pipeline that runs from Wisconsin to Illinois, from 560,000 barrels per day to 1.2 million barrels per day. Opposition to the company’s operation of a pipeline that runs beneath the Straits of Mackinac, where Lake Michigan and Lake Huron join, has been especially fierce, though the line does not currently carry tar sands oil.

“I think at the very least we should be saying no to more tar sands through the [Great Lakes] region until we get a firm handle on how to deal with the unique challenges that tar sands spills present,” Murphy said. “We should also be taking a hard look, as the president did with the Keystone XL decision, about the other negative impacts of more tar sands oil, like the consequences in Alberta with the habitat destruction there, and also the higher carbon pollution content of the fuel.”

The National Academies study concluded that the characteristics of diluted bitumen are “highly problematic for spill response because 1) there are few effective techniques for detection, containment, and recovery of oil that is submerged in the water column, and 2) available techniques for responding to oil that has sunken to the bottom have variable effectiveness depending on the spill conditions.”

“Broadly, regulations and agency practices do not take the unique properties of diluted bitumen into account, nor do they encourage effective planning for spills of diluted bitumen,” it continued.

The study’s authors made a series of recommendations to help reduce the damage from future tar sands spills, including:

  • Update regulations that would require pipeline operators to identify and provide safety sheets for each crude oil transported by the pipeline, catalogue the areas and water bodies that would be most sensitive to a diluted bitumen spill, describe how they would detect and recover sunken oil, provide samples and information about the type of oil spilled to emergency officials, and publicly report the annual volumes and types of crude oil that pass through each pipeline.
  • Require the Pipeline and Hazardous Materials Safety Administration (PHMSA), the federal agency that regulates pipelines in the United States, to review spill response plans in coordination with the U.S. Environmental Protection Agency and U.S. Coast Guard to determine if the plans are capable of responding to diluted bitumen spills.
  • Develop methods to detect, contain, and recover oil that sinks to the bottom of water bodies.
  • Require government agencies at the federal, state, and local level to use industry-standard names for crude oils when planning spill responses.
  • Revise oil classifications used by the U.S. Coast Guard to indicate that diluted bitumen can sink in water.
  • Collect data to improve modeling of diluted bitumen oil spills.
    Improve coordination between federal agencies and state and local governments when planning and practicing oil spill response exercises.
  • Develop a standard method for determining the adhesion –a measure of how sticky the oil is–of diluted bitumen in the event of a spill.

After the study’s release, PHMSA said it would develop a bulletin advising pipeline operators about the recommendations and urge voluntary improvements to their spill response plans. The agency also plans to hold a workshop next spring to hear public input on how to implement the recommendations, coordinate with other federal organizations to “advance the recommendations”, and work with industry representatives to improve spill response planning.

“We appreciate the work the National Academy of Sciences has done over the last few years in analyzing the risks of transporting diluted bitumen, including its effects on transmission pipelines, the environment and oil spill response activities,” Artealia Gilliard, PHMSA spokesperson and director for governmental, international and public affairs, said in a statement. “All pipelines transporting crude oil or any other hazardous liquid are required to meet strict federal safety regulations that work to prevent pipeline failures and to mitigate the consequences of pipeline failures when they occur.”
