Important Note: The figures in the table are rounded off estimates, not exact numbers. If you’d like to get a more exact, computer-calculated estimate of your GHGs and how you can reduce them, go to one of these computer calculators: |

How could you make changes in your home that would reduce your greenhouse gases (GHGs) by one tonne? You can take actions yourself, and you can also talk to your family and friends to try to get them to take some actions. This table tells you how you can reduce GHGs. You can reduce your GHG emissions by individual actions that you can do yourself, and you also get credit for encouraging other people to take action. Go through the table and see what actions you and your family can take to reduce GHGs.
In 2000, Canadians generated over 31 million tonnes of waste – over 1 tonne each! 23 million tonnes were sent for disposal – imagine 21 football fields piled 1 km high with garbage!
It takes a lot of fossil fuel to make things in factories and to get them to the store – and burning that fossil fuel puts GHGs into the air. The more stuff you buy, and the more you throw away, the more GHGs you create. Try using less. When you recycle, you also help to reduce your GHGs. It takes a lot more energy to make products out of raw materials than it does to re-make them out of recycled material.
This table shows the kilograms of GHGs reduced per year by one person. If you can get other people to do actions, you get credit for that, too. Check out the example, to see how this works.

Cut down on “stuff”Every time you buy something, fossil fuels are used to make it, package it, and drive it to the store. After you use it, it often goes to the dump and produces more GHGs when it rots. |
If you decide to buy only things you really need, you could reduce your GHGs by 50 kg per person, per year. |
e.g.: 50 kg – because I’m going to cut back
on new clothes and toys. |
50 kg – |
100 kg |
Re-use and recycle.When you recycle, you save energy. It takes less energy to make things from recycled materials (like recycled paper) than to make things from raw materials (like wood). Studies show that over half of our garbage could
be either recycled or composted. |
If you can reduce your garbage by one-quarter (put out 1½ garbage bags instead of 2), you reduce your GHGs by 125 kg per person. |
|||
Compost your veggie scraps.When we don’t compost our fruit and vegetable waste, it goes into landfills. When it rots, it creates methane – one of the main GHGs. Learn more about
composting at http://www.compost.org/ |
If you compost, you can reduce your GHGs by 40 kg per person. |
|||
Recycle your grass clippings.If you put your grass
clippings in the garbage, they also rot in the landfill and create
methane. A better idea: keep grass clippings on your lawn where
they break down and feed the lawn. |
If you keep grass out of your garbage, you can reduce your GHGs by 30 kg per person. |
|||
Buy local food.A lot of the food you eat comes from far away. In fact, the average food item travels 2000 km to arrive at your table. All that driving uses a lot of energy! |
If you buy foods grown close to your home, you can reduce your GHGs by 50 kg per person. |
Driving around in cars creates a lot of GHGs. If we can drive less (by walking, biking, car pooling, or bussing), we can reduce our GHG emissions.

Drive less.Driving is responsible for almost half of the average Canadian's personal GHGs. For every 4 km you don’t drive, your family reduces 1 kg of GHGs. |
If you drive less (by walking, biking, bussing, and carpooling with your friends), you can reduce GHGs by 125 kg per person. |
e.g.: 125 kg – |
250 kg – |
375 kg |
Don’t idle.Idling is a big problem in the North – spewing out piles of GHGs. Although many people think idling is good for their engines, it isn’t. According to car makers, it is best
for your engine to idle for no more than 30 seconds on winter
days before driving away. Try keeping warm with a blanket instead
of
warming your car before you start. |
If you reduce your idling by 10 minutes per day, you reduce 60 kg per person. |
|||
Slow down.When you slow down, you
save gas. If you slow down on the highway by 1 km per hour, you
save 1% in gas costs.
(If you slow down by 5 km per hour, you save 5% in gas costs.)
You also reduce your GHG emissions. |
If you can get your family to slow down on the highway, you can reduce GHGs by 40 kg per person. |
|||
Switch to ethanol-blend gasoline.Some gas stations sell ethanol-blend gas. This gas replaces some of the gasoline with ethanol – a type of alcohol made from grain. Using ethanol-blend gas helps to reduce GHGs. If all gasoline in Canada was blended
with ethanol, we could reduce our GHGs by 5 million tonnes per
year. |
If your family switches to ethanol-blend gas, you can reduce GHGs by 50 kg per person. |
|||
Check your car; check your tires.If your car isn’t
running properly, and if your tires are squishy, it will use a
lot more gas. |
If you can get your family to check the tires every
month and tune up the car, you can reduce GHGs by 100 kg per person. |
|||
Cut back on air travel.Just ten hours of air travel can produce one tonne of greenhouse gas emissions per person! |
If you cut back by one long airplane ride (e.g., Whitehorse to Vancouver, which is 5 hours return), you can reduce your GHGs by 500 kg per person! |
When you heat your home, you create GHGs. And the problem is – we waste a lot of heat!

Check your weather-stripping around doors/windows and caulk up any cracks.Air leakage can waste almost half of the heat in
your
house! Weather-stripping and caulking will stop all that warm air
from escaping – and save money, too. |
If your family uses caulking and weather-stripping, you can reduce your GHGs by 65 kg/yr. per person. |
e.g.: I try to persuade my family to weather-strip the whole house. |
130 kg – |
130 kg |
Lower the temperature at night and when nobody is home.At night, it’s usually more comfortable to have the temperature cooler, and doesn’t make sense to heat the house when no one is home. |
If you lower the thermostat when you aren’t at home, or overnight, you reduce your GHGs by 200 kg/yr per person. (Note:
This is based
on an average of different types of heating.) |
|||
Upgrade your insulation.The more insulation in your attic, walls and basement, the less energy is needed for heating. |
Putting more efficient insulation into basement and above-ground walls, and in the attic can reduce heat loss by about 250 kg per person. |
Water heating accounts for a lot of the greenhouse gas emissions produced by an average Canadian home. Time to cut down!

Install low-flow showerheads. (And shorten those showers!)One-third of your family’s water heating bill probably goes to pay for showers. If you install low-flow showerheads, you can have a great shower with only half the amount of water. The good news is that low-flow showerheads are cheap and easy to install! Even without
low-flow showerheads, you can reduce GHG emissions by taking
short showers
(5 minutes is plenty to get you clean, and takes much less water
than a bath). |
Option 1: If you install low-flow showerheads, you can reduce 75 kg of GHGs per person. Option 2: If you take short showers instead of baths, you can reduce 35 kg of GHGs per person. |
e.g.: 35kg – |
300 kg – |
335 kg |
Use cold water to wash your clothes.About 1/4 of all
the hot water you use in your household is used to wash clothes.
And clothes can get just as clean in cold water, especially using
a cold-water detergent. |
If you wash your clothes with cold water instead of hot water, you can reduce your GHGs by 150 kg per person. |
|||
Fill up the dishwasher before you run it.Use the energy-saving setting to dry the dishes. Tip: Scraping off the dishes instead of rinsing saves hot water, too. |
If you load your dishwasher before you use it, and use the air-dry cycle, you can reduce your GHGs by 90 kg/yr per person. |
The lights and the appliances in your home use a lot of energy, and create a lot of GHGs. This is especially true if you live in an area where electricity is produced by burning diesel, like NWT or Nunavut. You can reduce a lot of GHGs if you reduce electricity use at your house.
(Note: The figures in this section are an average of the GHG emission rates from Yukon, NWT and Nunavut.)

Turn off the lights when you’re not using them. |
By turning off the lights when not needed, you can
reduce your GHGs by 20 kg per person. |
|||
Replace your light bulbs with fluorescent or halogen bulbs.Compact fluorescent and halogen bulbs use much less electricity than standard light bulbs, and last a lot longer. |
If you replace 5 of your 60 W bulbs with 13 W compact
fluorescent bulbs, you reduce your GHGs by 30 kg per person. |
|||
Turn off TV, computer and equipment when not in use.A
computer that runs 24 hours a day uses up to $120 worth of electricity
each year. |
If you shut off lights and equipment when not being used, you reduce your GHG emissions by 20 kg per person. |
|||
Get rid of the second fridge.Do you really need that
second refrigerator? It could be responsible for one-tenth or
more of your home's electricity bill. |
If you get rid of your older, second fridge, you can reduce your GHG emissions by 75 kg per person. |
|||
Limit use of gas lawn mowers and snow blowers.Gas-powered mowers cause a lot of pollution. |
If you use push-power instead of gas-power to mow
the lawn, you can reduce your GHG emissions by 10 kg per person. |
|||
Bonus Points – write a letter.Write a letter to a political representative or to the editor of your paper, suggesting actions to reduce GHG emissions. |
Writing letters is one way to influence lots of people. Give yourself a credit of 100 kg. |

Here are some ideas that might help your students keep their one-tonne commitments.
Having even one other person who is trying to do the same thing will often give people the motivation to keep on trying. What about helping to establish a network of groups who will support each other in trying to reduce their GHGs?
The challenge of having someone else who is trying to beat you is often enough to challenge people to new heights. What about a friendly competition between members of your class, or a competition between classes?
If people write out what they intend to do and post it somewhere that others can see it, they often feel more like carrying through.
Posting reminders around the classroom or house can help students remember what they intend to do, and why. Students might create reminders or mini-posters from some of the information in the Action Plan handout, and post them at home.
Why are we concerned about climate change? What things about nature are really important to us, important enough to make us cut down on our driving or consumption patterns? Take time to go out on the land with your students, and to talk about why it’s important to preserve our environment. Students may want to make a list.
Many of the individual ideas above will also help students to get their families inspired. Here are a few more.
Encourage students to discuss their concerns with their families. Working together on the Reduce GHGs Action Plan (Student Handout #2) is a good way to start discussion.
Students may want to get a written commitment from some of their family members and friends who promise to take action. Try discussing with your students whether they think this might be helpful, and what form these written commitments might take. Students might want to design a form to be copied.
Creating window signs such as: “Our family is reducing our GHG emissions to save this planet” might be one way of inspiring neighbours.
When you save energy, you save money, too. Check out the websites listed below for information on how much money families can save by reducing energy costs. That’s a good motivator!
Individual and family efforts are great, but it’s important to get other folks moving, too. How can your students inspire other people in your school or community to reduce their climate change impact? Here is a process your class might go through to decide on an action.
Students decide what they want to achieve, then create a goal statement, like:
This is the time to be creative. A good way to encourage creative thinking is to brainstorm ideas. The strategy your class comes up with needs to be one that works for your school and community.
Some strategies that have been used to promote environmental change include:
