Obama: Keystone must not increase greenhouse gases

President Obama said Tuesday he will not approve the Keystone XL pipeline if building it would generate more greenhouse gas emissions than not constructing it.

“The net effects of climate impact will be absolutely critical to determining whether this project will go forward,” he said.

He made his remarks about the pipeline as part of a broad policy speech on climate change on the campus of Georgetown University.

He described the new test for Keystone and a slew of climate initiatives as part of his generation’s moral obligation to protect the planet.
