(AP) — Nebraska opponents of the Keystone XL pipeline say they’re thrilled that President Barack Obama mentioned the project during his speech on climate change, but they aren’t backing off their campaign.

Obama said Tuesday that the Canada-to-Texas pipeline project should only be approved if it doesn’t worsen carbon pollution.

Bold Nebraska executive director Jane Kleeb says the president’s remarks could shift the debate toward two federal reviews.

One study by the U.S. State Department found the pipeline would have a negligible impact on greenhouse emissions. Another by the Environmental Protection Agency said emissions could be higher than the State Department predicts.

Pipeline supporters say the project has undergone exhaustive reviews at the federal level and in Nebraska. Opponents say the State Department report relies on information from the oil pipeline industry.
