Environmentalists Step Up Opposition to Keystone Pipeline

Opponents of TransCanada Corp.’s Keystone XL pipeline say they intend to make President Barack Obama hear their concerns after a March 1 report helped clear a way for White House approval of the project.

The pipeline drew a fresh wave of objections from groups including the Sierra Club, Natural Resources Defense Council and 350.org, when the U.S. State Department’s draft assessment said it won’t have a significant impact on global warming. Members of 350.org will confront Obama and Secretary of State John Kerry at all future public events, said Daniel Kessler, a spokesman.
