A brief description of the institution’s GHG emissions reduction initiatives, including efforts made during the previous three years:

Between 2010 and 2012, IU began phasing out the use of coal and increasing the use of natural gas in the Central Heating Plant (CHP).
In FY 2010, 92% of the fuel use in the CHP was coal, and 8% natural gas.
In FY 2017, 13% of the fuel used in the CHP was coal, and 86% natural gas.
Metric tons of carbon dioxide equivalent associated with coal burned at IU decreased 89% from 2010 to 2017, while GMTCDE associated with natural gas increased slightly. Overall, the CHP emissions during this timeframe resulted in a 51% decrease. This dip is more modestly reflected in IU's overall emissions reduction because the CHP only accounts for 24% to 36% of IU's total emissions footprint in a given year.

Excluding the dramatic jump in reductions since 2009-2010, when the Office of Sustainability was formed and began tracking emissions at IU, we still see a downward trend in emissions. Between 2013 and fiscal year 2017, for example, emissions decreased~7%, which we attribute to a decrease in campus electricity use due to increased efficiency measures like LED lighting, installation of light sensors, installation of window film, the IU Energy Challenge, and a standard for all new construction to be LEED certified.

In May 2018, the IU Office of Sustainability will convene a strategic planning session to discuss how IU can continue to decrease its emissions in the face of increasing cooling degree days and renovations which upgrade residential dormitory HVAC systems, including bringing central air to new spaces. We plan to also discuss best practices for decreasing IU's fleet fuel use, which has steadily increased over the years as the IU staff population grows.

IU looks forward to decreased electricity consumption at the IU Data Center -- naturally the building with the largest electricity consumption footprint -- due to heat exchanger upgrades in summer and fall 2018.

The 190 "other individuals resident onsite" includes average nightly occupants in the Biddle Hotel, part of the Indiana Memorial Union. This hotel is onsite and part of IU's energy, waste, water, and food footprint.

IU uses a custom fuel-mix emission factor provided yearly by Duke Energy.

All purchased utility data excludes REMC Electricity purchases at properties such as Bradford Woods (owned by IU but located 27 miles off campus), and other field stations. This electricity accounts for <1% of total electricity use, and this property is not reflected in total campus acreage or footprint (also excluded from vegetated grounds entry in OP9 and OP22 categories).

Because of staff turnover in the last seven years and multiple iterations and upgrades of CarbonMap and SIMAP, central heating plant production reports, fleet fuel invoices, custom Duke Energy fuel mix reports, and purchased electric invoices were pulled and confirmed for 2010-2017 accuracy by Makayla Bonney in April 2018 with the assistance of Erica Steinfeldt (Utilities Analyst), Mark Meneffee (Assistant Director, Utility Operations), Jeff Honaker (Account Manager, Duke Energy) and Amanda Wilson (Fleet Manager).

Questions associated with IU's fuel datasets or associated emissions reductions may be directed to Makayla Bonney, Assistant Director of IU Sustainability - mjbonney@indiana.edu
