Harper does not want to honour Canada's commitment
This speaks for itself:
Under the Kyoto accord, negotiated and ratified by the Liberals over Tory opposition, Canada is committed to a six per cent cut in greenhouse emissions from 1990 levels by 2012.
Experts say the target is likely not achievable through domestic action alone, but could be met through purchasing credits in UN-approved emissions-cutting projects abroad.
By some estimates this could cost about $10 billion by 2012. Harper has rejected the idea of international emissions trading, suggesting the money sent abroad would be wasted.
