The House of Representatives overwhelmingly passed a measure today authorizing the construction of the Keystone XL pipeline.

The Post reports that the bill was passed by lawmakers 252 to 161, with 31 House Democrats voting in favor of the bill, along with all but one Republican, Rep. Justin Amash (Mich.), who voted “present.”

The proposal for building the Keystone XL pipeline—an extension of the current Keystone pipeline system—calls for extending the system to transport oil from Canada to refineries in the Gulf Coast. The proposal, naturally, has been met with much controversy, with environmental advocacy groups claiming that the pipeline would “carry 800,000 barrels per day of tar sands oil across the U.S.,” which would leave a massive carbon footprint, “sometimes requiring more energy to produce than it creates.”

Now that it’s passed the House vote, the measure is set for a vote in the Senate. Meanwhile, President Barack Obama has said he’d only approve the measure to extend the Keystone XL pipeline if there can be a way to not “significantly exacerbate” the massive carbon footprint environmentalists and scientists say it will leave.
