Butler outlines campus plan to cut emissions, expand native plantings and scale composting

Summary
Butler University presented a multi‑phase decarbonization plan and campus sustainability initiatives — including rewilding, a 10‑year native planting target, and expanded composting — to the Indianapolis City‑County Council Environmental Sustainability Committee.
Butler University’s Office of Sustainability told the Indianapolis City‑County Council’s Environmental Sustainability Committee that the university is pursuing a multi‑phase plan to reduce campus carbon emissions while expanding native landscaping and student engagement.
Julia Engsman, executive director of Butler University’s Office of Sustainability, said the office — renamed in March 2024 after operating since 2018 as the Center for Urban Ecology and Sustainability — is focused on four areas: strategic energy management, on‑site renewables and EV charging, thermal transition toward electrification, and off‑site renewable procurement. “We officially got our new name in March of 2024,” Engsman said, and added that the university is working to “lower our emissions profile on campus as effective as possible.”
The university’s decarbonization effort grew from a 2012 climate commitment to reach carbon neutrality; a board of trustees decision last February accelerated planning and funding for the effort. Engsman said Butler contracted engineering firm HEPI to develop a decarbonization master plan. Phase 1 — strategic energy management — includes building controls, motion‑sensor and LED lighting upgrades, retro‑commissioning and targeted deep energy retrofits. Phase 2 centers on solar, geothermal and expanded EV charging. Phases 3 and 4 address thermal electrification and off‑site renewables; Engsman said full thermal electrification is likely 10–15 years out to align with utility and grid changes.
Engsman described on‑campus landscape changes the committee can already see. Butler manages about 50 acres of forest, a 1‑acre agroecology farm that supplies campus dining, a 4‑acre research prairie and a network of bioswales and rain gardens that manage runoff. She said the university has a 10‑year goal to “rewild” at least 23 acres by converting low‑value turf and hard‑to‑mow areas into native plantings, and that volunteers recently replanted historic Holcomb Gardens with native species.
“We had a huge volunteer event with 400 volunteers that came out and helped us plant nearly 4,000 plants in one day,” Engsman said, calling the effort both an educational opportunity and a way to reduce mowing and chemical inputs.
On waste, Engsman said students and interns completed a campus waste audit that produced about 60 recommendations emphasizing waste minimization, reuse and diversion over recycling alone. Butler currently composts roughly 650 pounds of food waste per month from back‑of‑house kitchen operations and is evaluating anaerobic digestion to accept meat and dairy and expand composting beyond kitchen waste. Engsman said front‑of‑house composting remains at higher risk of contamination and requires additional operational controls.
Student engagement is central to Butler’s approach: Engsman said the office employs 12 interns who work on audits, grounds projects and community placements with partners such as the White River Alliance and the Global Center for Species Survival. She said Butler reports greenhouse gas emissions to Second Nature and participates in the Association for the Advancement of Sustainability in Higher Education (AASHE), where institutions receive bronze, silver, gold or platinum ratings; Butler currently holds a silver rating.
Committee members asked about near‑term cost savings. Engsman said LED retrofits typically return investment within a handful of years and that waste diversion and move‑out donation programs are expected to reduce hauling costs. On EV charging, she said Butler is prioritizing electrifying its fleet using utility incentive programs and also evaluating public charging to serve visitors and event attendees.
Chair John Barth praised the Holcomb Gardens restoration and encouraged community visits once plantings mature. Several councilors said Butler’s student programming and volunteer events help translate campus sustainability into community engagement.
The presentation closed with committee members thanking Engsman and noting interest in continued collaboration between Butler and city sustainability initiatives.
