The government has annouced that $10 Billion dollars will be spent over the next 7 years to curb greenhous gas emissions by 270 megatonnes a year from '08 to '12.
Commitments (from government activities) include:
-Cut emissions from its facilities and activities by one-third.
-Draw 20 per cent of its electricity from renewable sources by 2010.
-Ensure new office buildings meet the highest environmental standards.
-Replace its vehicles more quickly and with fuel-efficient alternatives including hybrids.
"...the government and the industry had already reached agreement on a voluntary deal under which the automakers will produce cars that cut emissions by 5.3 megatonnes a year by 2010."

Plans are to increase production of electricity from renewable resources.
Which is a good thing, as per capita, Canada is the largest consumer of energy in the world.
