A brief description of when and why the GHG emissions baseline was adopted:
While the University adopted a baseline from 2005 for measuring GHG emissions, Notre Dame began tracking and conserving well before that year and continues to use this baseline moving forward in setting aggressive goals for continued reduction of GHG emissions.

A brief description of the institution’s GHG emissions reduction initiatives:
Notre Dame President Rev. John I. Jenkins, C.S.C., announced in the fall of 2015 the ambitious goal of discontinuing the use of coal by the end of 2020 and cutting the University’s carbon footprint in half by 2030. Both goals have been achieved ahead of their target dates.

Because of combined efforts laid out in the University’s Comprehensive Sustainability Strategy, Notre Dame has achieved a 50 percent reduction in carbon emissions per gross square foot based on 2005 levels, accomplishing the goal well before 2030. The University accomplished these goals by reducing energy consumption, diversifying its energy sources, and expanding and evolving its energy infrastructure to increase efficiency and capacity.

Since 2008, the University has implemented numerous energy conservation measures including installing energy-efficient lighting, establishing temperature set points, tightening building operating schedules, optimizing lighting and HVAC controls, using low-flow water devices, installing a computer-based irrigation system, applying energy analytics, applying variable-frequency drives on pumps and fans, installing the state’s largest green roof system and pursuing a minimum of LEED silver certification standards for all new construction. When aggregated, the energy conservation measures not only contribute to a reduction of carbon emissions, but also generate an annual savings of more than $2 million.

Notre Dame’s implementation of technology has further increased its energy efficiency. The University began using two new natural-gas-fired combustion gas turbines with heat-recovery steam generators earlier this year. These units operate in a combined cycle with other existing systems to produce both electricity and steam. This energy production is twice as efficient as a traditional electrical plant. The steam produced through the heat-recovery steam generators, powered in part by the gas turbine exhaust, is further used to heat campus, produce hot water or drive equipment to provide air conditioning for campus.

The University is also diversifying its energy sources to include renewable and recoverable energy from geothermal, solar, and hydroelectric technology.
