David Jacobson, the U.S. ambassador to Canada said that President Obama's climate change initiative was also a challenge to the Canadian government.
Saying that the climate policies laid by president Obama would have impact on Canada, the ambassador interpreted Obama's state of the union message as an urge to balance the ecology and technology.
"I believe what he was trying to say was that we, in the U.S., have to do better with respect to carbon, we have to do better with respect to climate change," David said in an interview with CBC News.
"The president is very serious that we need to do a better job with respect to our carbon footprint - he believes that global warming is a real problem. There is no question, it's a priority," CBC News quoted the ambassador, as saying.
Obama Tuesday vowed to reduce the green house gas emissions and increase the energy security.
Following Obama's speech, several environment activists protesting against the Trans Canada's proposed keystone XL pipeline were arrested in Washington. Obama made no statement on the pipe line business in his speech.
"Canadians have not been well-represented by our government on action on climate change. Fortunately for Canadians, though, the Harper Conservatives will have little choice but to follow suit or risk our trading relationship with our biggest partner," 1310 News quoted Megan Leslie, a spokesperson of the National Democratic Party as saying.
The Obama's government in recent weeks gave the green signal to the $15.1 billion Nexen's takeover by the Chinese national company CHOOC.
The deal had to get U.S. approval because Nexen Company controls significant assets in the Gulf of Mexico.
Handover of the Calgary based global gas and oil Company to the Chinese state owned company was the biggest foreign takeover in Canadian history.
