The one tonne challenge

The One Tonne Challenge

Government of Canada


One tonne challenge overview

One Tonne Challenge - Overview

  • A challenge to Canadians to reduce their GHG emissions by one tonne or by 20% of their total emissions produced each year.

  • Three year program that should start soon


What is being asked of canadians

What is being asked of Canadians?

  • Drive « smarter » and drive less

  • Increase home energy efficiency

  • Purchase energy efficient appliances

  • Supporting activities – buy locally, conserve water, practice 4Rs


Tools for canadians

Tools for Canadians

  • Guide to the One Tonne Challenge

  • Greenhouse Gas Calculator (educates individuals about their GHG contribution and gives examples of actions and the « savings » brought about by these actions)

  • One Tonne Challenge Web site

  • OTC kit


Set up a otc

Set up a OTC !

  • Take up the challenge in communities, organizations, employers, in a school, between classes, or challenge a neighbouring school

  • Not only can students do things to reduce their own energy use and GHG emissions, they can get their families involved.


What is a tonne

What is a tonne?

  • 1 tonne = 1 000 kilograms (2200 lbs.) or 300 litres

  • The volume of one tonne of CO2 would completely fill the inside of an average two-story, three bedroom house

  • Weight of 5 baby elephants

  • Weight of 30 ten-year olds

  • Under the Kyoto Protocol, our commitment is to reduce our GHG emissions to 6% below 1990 levels by 2012 or by 240 MT.

  • Each canadian generates just over five tonnes of GHG emissions each year.


Actions to achieve the one tonne goal

Actions to Achieve the One Tonne Goal

  • Mid-sized sedan driven 20,000 km/year produces 4 tonnes/year

  • SUV – 20 000km/year = 6 tonnes/year

  • Gasoline-electric hybrid = 2 tonnes/year

  • Driving 10% less, by taking public transit, walking, cycling, or carpooling, can reduce greenhouse gas emissions by 0.2 to 0.8 tonnes per year, depending on the vehicle.


Actions to achieve the one tonne goal1

Actions to Achieve the One Tonne Goal

  • Using 10 litres of gas less a month, by carpooling or walking, can save one-quarter (0.25) of a tonne in GHG emissions in a year.

  • Replacing an old vehicle with a more fuel-efficient model can save up to 2.5 tonnes of GHG.

  • If every Canadian motorist avoided idling their vehicles for 5 minutes a day, all year, more than 1.6 million tonnes of CO2 would not enter the air.


Actions to achieve the one tonne goal2

Actions to Achieve the One Tonne Goal

  • Replace appliances with more energy-efficient models (a 2002 refrigerator uses less than half the electricity of a 10 year old model, saving more than $40 per year on a home energy bill and reducing emissions by more than 0.2 tonne).


Actions to achieve the one tonne goal3

Actions to Achieve the One Tonne Goal

  • Computers and monitors account for approximately 7% of electricity consumption in a typical office. Reduce GHG emissions by turning off the computer at night.

  • Trim home heating bills by up to 10% and reduce emissions by up to 0.5 tonnes.


Actions to achieve the one tonne goal4

Actions to Achieve the One Tonne Goal

  • Install a programmable thermostat to lower the heat by 5 degrees at night and when the house is unoccupied. This can reduce your GHG by 0.5 tonne/year.

  • Buy food and other products with reusable, recyclable or reduced packaging. This can reduce your GHG emissions by 0.1 tonne/year.


One possible scenario

One possible scenario

  • Drive 10% less = 0,4 tonne

  • Reduced packaging = 0,1 tonne

  • Install a programmable thermostat = 0,5 tonne
