Lost in the heated arguments over Kinder Morgan's proposed Trans Mountain pipeline is this simple fact: more than a quarter of the bitumen flowing through it will end up as pollution spilling into our oceans — one way or the other.
All the bitumen that doesn't spill from pipelines or tankers gets burned, ending up as carbon pollution dumped into our environment. Over one quarter ends up in the oceans, acidifying them for millennia to come.
So far, over 12 billion barrels of bitumen have been pulled out of the ground in Alberta.1 After being burned in trucks and cars, the resulting carbon pollution has all been dumped (aka: spilled, emitted, released) into our air and water. The total so far? Twelve billion barrels of bitumen (~6.3 GtCO2).3
Where did it all go?
According to the International Panel on Climate Change (IPCC), about 28 per cent of all burned fossil carbon has ended up in our oceans causing them to acidify rapidly.4 Known impacts of "ocean acidification" include killing coral reefs; dissolving baby oysters, scallops and other shellfish; and scrambling marine food chains.
Over three billion barrels worth of Alberta bitumen (~1.75 GtCO2) has now entered the world's oceans.
The percentage of all that ocean pollution which humans have cleaned up? Zero. And the resulting ocean acidification will persist for tens of thousands of years — many times longer than human civilization has existed.
Another 48 per cent of burned fossil carbon stays in our atmosphere. It thickens the heat-trapping blanket around the planet, increasing the heat and energy in our weather systems via global warming. That’s why we’re getting rising seas and heatwaves, fiercer storms and droughts, surging wildfires and floods, and widespread ecological damage.
So far, over five billion barrels worth of bitumen (~2.7 GtCO2) have been dumped into our air. None of that has been cleaned up either.
Double the 'spills' with Trans Mountain
Kinder Morgan's new pipeline aims to pump as much new bitumen as Alberta has extracted in the entire history of the oil sands.
More than a quarter of the bitumen flowing through Kinder Morgan's Trans Mountain pipeline will end up as pollution spilling into our oceans — one way or the other.
The pipeline is designed to pump 890,000 barrels a day. Over a forty year operational lifespan that adds up to 13 billion barrels. (Note that the original Trans Mountain pipeline is still pumping after 65 years.)
Doubling the amount of bitumen extracted will obviously double the amount of bitumen pollution dumped in our environment:
- Nearly two billion more tonnes will get "spilled" into our oceans, further increasing our ocean acidification crisis.
- Three billion more tonnes will get "spilled" into our atmosphere, further increasing the climate crisis.
- And, as with past bitumen pollution, there are no plans to clean any of it up.
One way or the other, bitumen, like other fossil fuels, will pollute our oceans. Whether this fossil carbon gets spilled in liquid, solid or gaseous form, it will cause lasting damage to marine life, to coral reefs, to fisheries and to the people who cherish and depend on our oceans.
There is no scenario in which bitumen doesn't "spill" into our oceans causing harm. And there is no proposal to clean up any of the billions of tonnes of acidifying pollution that will end up there.
NOTES & SOURCES:
- Over 12 billion barrels of bitumen have been extracted in Canada since 1967 according to data in Canadian Association of Petroleum Producers (CAPP) "Statistical Handbook 2017".
- Each barrel of bitumen creates around 0.521 tCO2 when burned according to estimates by Oil Change International.
- The bitumen CO2 math: 12.08 billion barrels x 0.521 tCO2 = 6.3 GtCO2
- The International Panel on Climate Change estimates that ~44% of human-added CO2 has remained in the air; ~28% has been absorbed by the oceans; and ~28% has been taken up by plants and other land sinks. (see Section TS.2.8.1 of AR5 WG1 report)
Editor's note: This article has been updated with a new headline to clarify that the bitumen that wound up in the oceans was absorbed as carbon pollution.
