Q:
What’s the best way to
reduce my carbon footprint
through my diet?
A: As a
friend, I should tell you
that you’re looking a little
bloated these days. We all
are. When researchers
measured the greenhouse
gases that are swallowed up
in the average Canadian
household’s diet, our annual
food-related GHG emissions
were almost twice that of
our driving habit!
That’s saying a lot,
considering the abysmal fuel
efficiency of North American
cars.
Now, just imagine if Jenny
Craig were an
environmentalist. Instead of
handing out frozen
calorie-restricted Chicken
Kievs to weight-watching
individuals, an army of
earth-friendly counsellors
would advise us on getting
our greenhouse gases down to
a trim size 4,
metaphorically speaking.
So how do we take the weight
off? Turns out counting the
carbon footprints of food
items is a lot trickier than
counting calories. Hidden
carbon calories are lurking
at every turn. When one UK
crisps maker wanted to
reduce its carbon footprint,
it was advised to use
potatoes with less moisture
content so they’d be lighter
to transport and faster to
fry. Who’d have thunk it?
The precise conditions under
which your food was grown,
processed and sent to you
varies from farm to farm,
factory to factory and fruit
cup to fruit cup.
Yes, eating locally grown
food is an important start,
so a breakfast of Ethiopian
coffee with a teaspoon of
imported cane sugar and a
tropical fruit salad will be
way more fattening,
climate-change-wise, than a
bowl of Canadian steel-cut
oats with a local sliced-up
apple.
Of course, the dirtiness of
the diesel truck that
brought you the apple could
theoretically put it behind
a mango shipped in a modern,
more fuel-efficient boat
(although shipping is a
grimy, fuel-heavy business).
But food miles only
contribute anywhere from 2
to 11 per cent of your
meal’s total greenhouse fat.
If that local cuke was grown
in a hothouse mid-January,
then its footprint is
probably larger than the
field-grown one from
California.
So eating regional food
seasonally is key.
Add a strip of meat to that
meal, though, and it won’t
just be cholesterol making
your heart skip a beat.
Livestock produce more
greenhouse gases than all
the world’s cars, trucks,
planes, ships and trains
combined. But cows are the
real bad boys.
Grill up four half-pound
steaks and you might as well
get in your compact car and
drive 250 kilometres (while
leaving the lights on at
home for 20 days straight),
according to Japan’s
National Institute of
Livestock and Grassland
Science.
The Worldwatch Institute
says grass-fed cows produce
40 per cent less GHGs, but a
University of Manitoba study
concluded just the opposite.
Either way, if North
Americans ate one less meat
meal a week, as the head of
the UN advisory panel on
climate change is asking us
to, it would be the
equivalent of a mass shift
from driving sedans to
Priuses.
Sadly, cooped-up
battery-caged chickens have
a much smaller greenhouse
footprint, even smaller than
free-range organic chickens,
which tells you not all
things low-carb(on) are
truly ecologically and
ethically sound.
Organic grains and produce
are, for the most part, a
different story.
Fossil-fuel-based
fertilizers are seriously
greenhouse-gas-heavy, so
cutting them out means
organic wheat or canola, for
instance, produce 77 per
cent less GHGs and use 39
per cent less energy.
Not that vegetarians should
assume they’re holier than
thou – dairy’s another major
carbon source. Vegans are
the only ones with bragging
rights in this game,
especially if they eat
produce grown on veganic
manure-free farms – no joke
– and minimize their
munching on heavily
processed soy proteins, aka
fake meat.
If you skip the individually
packaged and frozen options
(sorry, Jenny Craig), you’ll
drop another carbon notch on
your belt. Stop buying more
food than you need so that
you don’t end up tossing up
to 30 per cent of it (like
most North Americans) and
you’ll soon turn into a
climate-friendly champion.
The Japanese and Brits are
actually bringing in carbon
labels on hundreds of food
items to make it easier for
consumers to figure all of
this out. And while there
are rumours that Loblaws is
considering the same idea, I
wouldn’t hold my fork.
But you can get a rough idea
of how many carbon calories
are hidden in your side
salad or chicken tenders at

Environmental Considerations
Meat and dairy production squanders natural resources and puts a substantial strain on the environment. One acre of land will produce many times the amount of vegetables that it will meat. It also takes many more times the amount of grain to feed people by way of finished meat products than it does to feed people directly from the grain . By reducing the amount of land used for agriculture to feed animals, we also substantially reduce the amount of petroleum-based insecticides and herbicides used in our modern intensive farming techniques. Many acres of land could be returned to a natural state. Eating lower on the food chain assists greatly in environmental sustainability.
A few fast facts
- 20,000,000 people die per year as a result of malnutrition and starvation.
- One half Earth's land mass is grazed by livestock.
- One half of world grain harvest consumed by livestock throughout the 1980's.
- 100,000,000 people could be fed with a 10% decrease in North American meat consumption.
- 40,000 pounds of potatoes can be produced on an acre of prime land.
- 250 pounds of beef can be produced on an acre of prime land.
- 78 calories of fossil fuel are used to produce one calorie of beef protein.
- 2 calories of fossil fuel are used to produce one calorie of soybean protein.
- Livestock production accounts for more than half all water use in the U.S.
- 26,000,000 tons of topsoil is lost annually on agricultural land.
- 200 - 1000 years for nature to create one inch of topsoil.
- 35 pounds of topsoil is lost in the production of one pound of feedlot steak.
- Cattle producing land the world over is the most affected by desertification.
- 52,000,000 acres of land annually becomes unproductive due to desertification.
- 29% of Earth's land mass currently suffers from desertification.
- 125,000 sq. miles of rainforest is destroyed annually.
- 1000 species become extinct annually due to rainforest destruction.
- Cattle production is the leading cause of deforestation in Central America.
- 70% decrease of woodlands in Canada due to animal agriculture
