A brief description of the institution’s GHG emissions reduction initiatives:

Northwestern is committed to identifying innovative solutions to advance energy conservation and reduce the institution’s carbon footprint.

GHG Emission Reduction initiatives include:
• Released in 2017, the University’s Strategic Sustainability Plan (SSP) sets goals and strategies to reduce energy use intensity by 20 percent by 2020 compared to a 2010 baseline and achieving 30% reduction in carbon emissions by 2030 compared to a 2012 baseline.
Adopted an Energy Conservation Policy in 2017 to guide on-going implementation of our energy management efforts.
Requiring new construction and renovation projects to reduce energy use by at least 50% below ASHRAE 90.1-2010 and achieve no less than Leadership in Energy and Environmental Design (LEED) Gold certification for new construction
19 LEED certified buildings, including Platinum for Kresge Hall and Kellogg Global Hub
Geothermal facilities at the New Kellogg School of Management Building, and Segal Visitor's Center on campus.
Three solar installations on camps - Ford Engineering Design Center (17 kW), Kresge Hall (81kW), Ryan Field House (122kW)
