According to the U.S. Environmental Protection Agency, volatile organic compounds (VOCs) are gases emitted from certain solids or liquids that may cause adverse health effects. VOCs are released by a wide array of household products including paints, aerosol sprays, disinfectants and even office supplies such as glue and permanent markers. As part of its responsible environmental stewardship efforts, Duquesne has implemented a selection process that limits the VOC levels of the cleaning products, paints and other chemicals purchased by the University. An estimated 80% of the cleaning products used on campus are environmentally friendly, with low or no VOC content. And for two years the University has invested in high-quality, VOC-free paints that have been recognized for environmental standards.

1830 Gallons of Green Paint have been used from June, 2007.

Walk- off matting is also being used to reduce outdoor contaminants from traveling indoors.
