WASHINGTON, Jan. 22 (UPI) -- Environmental advocacy group Sierra Club was among those expressing optimism that U.S. President Barack Obama is going green for his second term.
The Sierra Club, in a statement, said it was "heartened" by Obama's emphasis on a low-carbon economy during remarks for his second inauguration.
"We will work tirelessly to ensure the transition to safe, clean energy sources to fight the most pressing challenge of our time," the Sierra Club said.
Obama said during an inaugural address Monday in Washington that, while the road toward a low-carbon economy may be difficult, the United States must take the lead in green initiatives.
"We cannot cede to other nations the technology that will power new jobs and new industries, we must claim its promise," he said.
Obama last year opened doors for wind energy development in the United States. This year, his administration is expected to make a decision on the Keystone XL pipeline. The pipeline from Canada faces stiff opposition from environmental groups opposed to tar sands oil, seen as more damaging to the environment than conventional oil.
Anti-tar sands group Oil Change International said "Obama talks tough" when it comes to a green agenda but is silent when it comes it issues like Keystone XL.
"If Obama is to have any credibility left on climate, he must stop the pipeline," the group said.
