A brief description of the institution's approach to plant stewardship:
The use of native plant species in Carnegie Mellon University landscaping is currently encouraged and recommended by Division 2, Section 02950 of the university design guidelines.

A brief description of the institution's approach to hydrology and water use:
Only 5 acres (5%) of 100 acres of permeable campus grounds are irrigated. Stormwater capture and retention has been used for all new development projects in the past 10 years to reduce runoff and stress on the municipal combined storm sewer infrastructure. In addition, the university has installed several water reuse systems. In 2017, we installed a 275,000 gallon cistern under our historic quad that captures storm water for use in our cooling plant. A 6,000 gallon grey water system captures rain water in a storage tank to be used for irrigating the grounds around the MCIC building. The hillside near the Gates Hillman Complex was engineered to capture storm water runoff from the hillside. There are also over 41,000 sq ft of green roofs on campus buildings.


A brief description of the institution's approach to landscape materials management and waste minimization:
Carnegie Mellon University composts all plant materials waste through a recycling contractor.
