ExxonMobil's
influential global energy report, "The
Outlook for Energy: A View to 2040",
says that new technologies like fracking and tar sands are unlocking
a gusher of oil and natural gas.
Our
ability to extract new sources of fossilized carbon is growing even
faster than we can burn them up. ExxonMobil reports that the amazing
surge in "unconventional" sources of oil and natural gas is
so great that humanity can continue to burn ever increasing amounts
of fossil carbon for well over a century.
And
that is exactly what they expect the world will do.
The
oil and gas giant expects humanity
will meet two-thirds of our increased energy demand by choosing to burn even more oil and gas than we do now.
will meet two-thirds of our increased energy demand by choosing to burn even more oil and gas than we do now.
In
contrast, they expect people to choose new renewable energy sources
for less than a quarter of our new energy supply.
The
result will be that renewable energy sources will continue to lose
ground to fossil fuels through 2040 and beyond. The energy production
gap between fossil fuels and renewable energy will grow 35% larger
than it is today.
ExxonMobil's
report paints a big, bright, beautiful picture of the future made
possible by burning ever increasing amounts of fossil carbon. The
pages of their report brim with happy people gazing at shimmering
cell phones and jelly bean pretty charts.
Off
the climate cliff
Unfortunately
for most of humanity, all that extra fossil fuel burning also comes
with one very big downside. If we do burn that much more fossil
carbon the resulting climate pollution will crank the global
thermostat up by 4OC.
And that, scientists and global leaders say, will inflict climate
misery on humanity for thousands of years.
ExxonMobil
includes a colourful chart showing the surge in climate pollution
that will result from burning all that extra oil and gas. They even
provide the numerical data in a table at the end of the report.
What
they don't talk about, however, is what all the climate pollution
means for your future. They never mention how hot the planet will get
or what changes that is expected to bring.
The
missing chart
To
find out what their expected levels of climate pollution will mean
for us I turned to the International Energy Agency (IEA). The IEA
publishes
three climate pollution scenarios that will lead to global warming of
+2OC,
+4OC
and +6OC
respectively.
My
chart below shows ExxonMobil's emissions projections in the context
of the IEA's three global warming scenarios. Take a look:
As
you can see, ExxonMobil's projections closely match the IEA pathway
to a planet that is 4OC
hotter.
Their
projections also closely match BP's "most
likely" projections
made last year. It seems the economic energy models of the oil
supermajors agree that humanity will continue to burn ever more
fossil carbon instead of switching to cleaner energy sources to
preserve a safe climate future.
Climate
scientists say that the threshold for "dangerous" climate
changes and tipping points is +2OC.
The nations of the world, including Canada and the USA, have pledged
to keep global warming below this dangerous +2OC
threshold.
"Devastating"
The
World Bank says the +4OC
world we are headed for will be "devastating"
for humanity. Their own recent study calls such a future a "climate
catastrophe"
that "simply must not be allowed to occur" because "there
is also no certainty that adaptation to a 4°C world is possible."
The
U.N. Secretary-General Ban Ki-moon says
climate changes at that level would pose an "existential
challenge for the whole human race - our way of life, our plans for
the future."
International
Monetary Fund director stated bluntly
that in a world that hot, "future generations will be roasted,
toasted, fried and grilled."
Biz-as-usual
will be even worse
Amazingly,
ExxonMobil's emissions projections aren't a "business-as-usual"
scenario.
They
assume "that governments will continue to gradually adopt a wide
variety of more stringent policies to help stem GHG emissions."
This includes a carbon price rising to $80 per tonne of CO2 (tCO2) in
OECD nations, like Canada and the USA.
A
carbon price of $80 is much too low to prevent climate disaster
according to ExxonMobil. And yet it is also far above what we have
the political will for so far.
BC,
Alberta and Canada
For
example, here in BC we have one of the highest carbon prices in the
world at $30 per tCO2. We would need to increase that $2 every year
for twenty five years in a row to get to $80 by 2040. But the
political will to increase it has evaporated. The current Clark
government has declared a multi-year freeze on it.
As
ExxonMobil's economic and energy modelling shows, $80 per tCO2 isn't
a lot. Raising the BC Carbon Tax to $80 will increase gasoline prices
by 9%. Gasoline prices in BC have increased ten times more than that
in just the last few years. Over in the UK, gas taxes are 80 cents
higher per litre than in BC. The BC Carbon Tax would need to rocket
beyond $350 per tCO2 before our gasoline prices matched what the
English already pay today.
These
examples show why carbon prices will need to be higher than $80 to
ensure a safe climate future.
Meanwhile,
Alberta next door charged a carbon price of less than $1 per tonne of
CO2 in their province last year. (Math: $160m paid in emissions
compliance divided by 210m tCO2 from fossil fuel burning = $0.76 per
tCO2).
Environment
Canada projects that Alberta's extremely low carbon pricing will
result in such a huge surge in climate pollution that the province
will single-handedly wipe out all the climate cuts in all the rest of
Canada.
Despite
clear warning that their weak policies are leading to national
failure, Alberta has never raised their carbon price. Even discussing
charging more than their current $1 per tCO2 in the future is proving
to be politically toxic.
At
the national level, the Harper government has vilified carbon pricing
for years as a socialist scheme that will destroy the economy.
Recently, Prime Minister Stephen Harper announced that his
long-promised climate regulations for our oil and gas sector would be
delayed yet again. This time "indefinitely".
ExxonMobil
reaps benefit, shirks responsibility
ExxonMobil
benefits from selling fossil fuels but appears to take no
responsibility for any of the climate damage their products cause.
They
sold over a trillion dollars in fossil fuel products in the last
three years. Profits approached a billion dollars a week. And yet the
responsibility they assume for the megatonnes of CO2 their products
will cause is zero. Their report mirrors this benefit-responsibility
disconnect. They spend many pages talking about the benefits of their
products and not a single word about the climate consequences of
using them.
Studies
show that the disconnect between who benefits from fossil fuels and
who takes responsibility for the resulting CO2 is growing ever wider
in recent years. More than 60% of global economic benefit from fossil
fuels is now out of sync with the UN's decades-old carbon accounting
system for CO2 responsibility.
The
UN accounting system puts all the CO2 responsibility onto the nations
that burn fossil fuels. But nations also benefit from selling fossil
fuels to others and from consuming products and services made
elsewhere using fossil fuels. The explosion in global trade in fossil
fuels, products and services means that assigning all the CO2
responsibility to those burning fossil fuels no longer accurately
reflects who benefits. The accounting system is full of "carbon
responsibility leakages".
If
we are going to avoid the "climate catastrophe"
ExxonMobil's own data shows we are headed for, everyone who benefits
from fossil fuels will need to start shouldering some of the
responsibility for the climate pollution. That needs to happen for
moral, fairness and successful policy reasons.
The
outlook for different energy sources
I'll
wrap up with a brief look at how ExxonMobil expects the different
energy sources to evolve...
Surge
in unconventional oil
ExxonMobil
expects nearly half of the oil supply in 2040 to come from
"unconventional" oil. As conventional liquid oil supplies
dry up ("peak oil"), new technology is stepping in to
convert gooey, solid and gaseous fossilized carbon into liquid form.
Even
as global oil production rises, the estimated size of the global
recoverable resource base continues to increase.
Globally,
while conventional crude production will likely decline slightly over
the Outlook period, this decline will be more than offset by rising
production from supply sources enabled by new technologies —
including tight oil, deepwater and oil sands.
By
2040, about 45 percent of liquids supply will be from sources other
than conventional crude and condensate production
Surge
in unconventional natural gas
Likewise,
an explosion of new technologies have unlocked tremendous amounts of
"unconventional" natural gas.
The
world has about 200 years of natural gas.
Estimates
of recoverable gas have doubled in the last 10 to 15 years as
hydraulic fracturing and horizontal drilling technologies have
unlocked the prospect of recovering unconventional gas.
About
65 percent of the growth in natural gas supplies through 2040 is
expected to be from unconventional sources
Coal
not the cause of increased CO2
ExxonMobil
projects that humans will increase coal burning for a decade or so
before cutting back slowly. By 2040 they expect coal burning to be at
the same level it is now.
However,
they also expect CO2 levels to be 19% higher by 2040. With coal
burning at the same level it means all the increase in CO2 emissions
in 2040 (up 19% from today) will be caused by increased oil and gas
burning.
Renewable
energy falls farther behind
By
2040, the report projects the energy production gap between renewable
energy and fossil fuels will grow spectacularly wider.
Today
fossil fuels produce 226 quadrillion more BTUs of energy than all
renewable energy sources. By 2040, ExxonMobil expects that gap to
grow to 305 quadrillion more BTUs from fossil carbon.
All
the global efforts to develop less climate damaging sources of energy
like wind, solar, geothermal, biomass, biofuels and hydropower will
lose ground to a far larger surge in "unconventional"
fossil carbon sources.
Simple
solution is waiting
The
solution to the climate crisis is simple: require climate pollution
to pay an ever-increasing fee for the damage it does.
ExxonMobil
itself prefers a simple carbon tax as the solution.
In fact they already
use
a $60 per tCO2 internal carbon price in their decision making.
As
their data shows, that carbon price will need to be a lot higher than
$80 per tCO2, and will need to appear a lot sooner than 2040, if we
are to avoid a future of extreme climate misery that their
emissions projections say is headed our way.
