UNITED NATIONS - U.S. President Barack Obama didn't just make announcements on behalf of his own country at today's United Nations climate summit -- he got to make Canada's, too.

Canada made two main commitments at the summit, where countries were urged to bring bold policies to fight climate change.

One was to match U.S. vehicle-emissions standards, the other to curb the use of HFC coolants.

Both came up as lines in Obama's speech to the conference, listed among the measures the U.S. had already announced.

Obama described having convened last week a group of business leaders who have committed to slashing HFCs by 80 per cent by 2050.

Later in the day, Environment Minister Leona Aglukkaq promised Canadian action on HFCs, a potent and fast-growing greenhouse gas.
