WASHINGTON, Nov 6 (Reuters) - U.S. Secretary of State John
Kerry on Friday said one key factor in his department's decision
to reject TransCanada Corp's TRP.TO Keystone XL oil pipeline
was the project's environmental impact.
"The critical factor in my determination was this: moving
forward with this project would significantly undermine our
ability to continue leading the world in combating climate
change," Kerry said in a statement.
