A BBC News article reports on a decision by the Canadian senate: -
'Canadian Prime Minister Stephen Harper's Conservative government has defeated a climate change bill calling for cuts in CO2 emissions.
Conservatives killed the motion backed by opposition parties 13 days before a UN climate change summit is held in Cancun.
The bill called for a reduction of greenhouse gases in the country by 25% from 1990 levels.
Canada's House of Commons originally passed the legislation last year.
It was then reintroduced in May and passed again, before being struck down by the Conservative-led Senate late on Tuesday.'
