The Trump administration is ending a policy implemented by former president Barack Obama that attempted to ban water bottles at national parks.

The National Park Service announced last week it was ending the so-called Water Bottle Ban, which the Obama administration implemented in 2011 to “reduce our carbon footprint.”

“In its commitment to providing a safe and world-class visitor experience, the National Park Service is discontinuing Policy Memorandum 11-03, commonly referred to as the ‘Water Bottle Ban,'” the agency said in a statement.

The National Park Service said the policy was counterproductive and only 23 out of 417 parks implemented the ban.
