The controversial pipeline Keystone XL should not be the only litmus test for which advocates for the environment judge a presidential candidate said Democratic president candidate Hillary Rodham Clinton.
She said advocates feel strong about their beliefs but she respectfully disagrees with those who say the Keystone project is an overriding threat world climate.
Clinton has declined on repeated occasions, unwilling to make political news, to state her position on the pipeline project, saying it would not be appropriate for her to prejudge a decision that President Obama might make about whether or not to approve it.
She said she was in a different position that the other presidential candidates who have already taken sides with the Keystone projects because of her prior role in the current administration.
The proposed pipeline would carry oil from the tar-sands deposits in Canada to refineries on the Gulf Coast of the U.S.
Because it crosses a border, it requires a State Department permit. The department started reviewing the project during the tenure of Clinton in the Obama Administration.
The White House administration has delayed repeatedly the decision saying it has to study it further.
The project is a rallying point in the climate change debate. Opponents see the Keystone project as a symbol of the continued dependence on fossil fuel and say that blocking it spurs on the transition to an economy that does not rely on oil.
In addition, they note the oil from the tar-sands is dirtier than other conventional oil and said its development of the reserve in Canada inevitably would increase the emissions of greenhouse gases.
Obama has stated that he would approve of the pipeline only if it can been demonstrated that it would not increase carbon dioxide emission as well as other greenhouse gases that are blamed for warming the climate across the globe.
Supporters of Keystone, who include GOP lawmakers and unions, argue it would provide the United States with another secure source of energy and generate new jobs.
They said as well that Canada would develop the tar-fields regardless if the pipeline were built and blocking its route into the U.S. simply shifts the oil to transportation methods that are less safe such as using rail cars.
