Take action on climate change. Step up to the One-Tonne Challenge.

The One-Tonne Challenge calls on all Canadians to reduce their individual greenhouse gas (GHG) emissions by one tonne - about 20 per cent.

The new One-Tonne Challenge program has been launched on March 26, 2004 and a new One-Tonne Challenge web section is now available on our Climate Change web site at http://climatechange.gc.ca.


The One-Tonne Challenge calls on all Canadians to reduce their individual greenhouse gas (GHG) emissions by one tonne - about 20 per cent. In February's Speech from the Throne, the Government of Canada reaffirmed its commitment to take action on climate change. So let's get involved.

You can meet the Challenge by using less energy, reducing waste and making smart consumer decisions. Your actions will save you money, protect our climate and help give us cleaner air. Visit the Government of Canada Climate Change web site at http://climatechange.gc.ca for more information.

Thank you for your interest in climate change!
