The Three Zeros
Net Zero Water
Our water conservation and reclamation efforts saved more than 210 million gallons of water in 2017. That’s about half of the water in University Lake.
Following two severe droughts, the University invested in innovative sustainable water management practices and conservation efforts, which have reduced potable water consumption by 32%, or more than 210 million gallons annually, since 2007, even with a growing campus population. Today, UNC-Chapel Hill is recognized internationally for its water conservation efforts.
Zero Waste To Landfills
In 2017, we diverted 45 percent of our waste from the landfill by recycling and composting.
Minimizing the waste we allow onto campus and recovering reusable resources are crucial components of achieving the University’s goals for a zero-waste campus. Efforts to reuse and recycle campus waste have significantly reduced the total amount of material UNC sends to the landfill: diverting 5,814 tons from the landfill in 2017, for a diversion rate of 45 percent, compared to 12 percent in 1990. This requires campus-wide sustainable materials management and individual behavior change.
Net Zero Greenhouse Gases
Since 2007, UNC has reduced our greenhouse gas emissions by 21 percent overall, even as the campus expanded in size.
The University works to become greenhouse gas neutral by reducing emissions through improving efficiency on campus, reducing coal use at the Cogeneration facility, increasing on-campus renewable energy and by working toward a strategy to purchase renewable energy. Innovative, renewable energy solutions, smart operational practices, individual choices to save energy, and new high-performance buildings have all contributed to significant energy and GHG emissions reductions.
