Financial Services is committed to making sustainable purchases for the College.  Below is the environmental clause on our vendor contract that all College contractors must sign.  Learn More >

Colby College is a carbon-neutral campus. The Contractor agrees to review the College’s ongoing energy and resource reduction priorities (below) and to strive to implement efforts to further those priorities.

Energy and Resource Reduction Priorities:

  • For services rendered for the College, we encourage the use of low impact, environmentally friendly alternatives. Some examples could be the use of alternatively fueled vehicles for car rentals or for printed materials asking vendors to use paper with high recycled content.
  • For products consumed at the College, we welcome products that reduce the embodied energy necessary to produce, package, transport, use, and ideally reuse or recycle the product. An example are products with minimal packaging made from recycled materials that are easily recycled into new products. 

Green Cleaning

In order to reduce exposure of building occupants and maintenance personnel to potentially hazardous chemical, biological, and particle contaminants, which adversely impact air quality, health, building finishes, building systems, and the environment and to reduce the deposition of contaminants in the building, Colby College has established green housekeeping policies and guidelines for the campus including the new Davis Science Center. All housekeeping duties are completed by Colby staff.

Sustainable Landscaping

Colby will continue to manage its landscaping and grounds in a manner consistent with best practices to minimize environmental impact. The Integrated Pest Management (IPM) system, in place since 1995 and rewritten in 2009, minimizes the use and toxicity of chemical applications. Leaves and grass clippings are centrally collected and composted. Brush and limbs are chipped and reused on campus. Building and landscape design will continue to be done to manage storm water runoff; Colby will strive to use only native or naturalized plants as landscaping is updated or added to campus.

Rainwater/Stormwater Management

As a part of Colby’s low-impact development practices, we have eight water runoff locations designed to treat rainwater and stormwater through low-impact strategies. These runoff locations are meant to remove any salt, sands, chemicals, and other sediments before the water is released.  The environmental program manager checks each runoff location twice a year to monitor their operation and perform maintenance as required. On average, each system is cleaned out for precipitated salts, sands, and other sediments every five to 10 years or as required.  One of our major runoff treatment areas is behind the Colby Green, where three large ponds are more than sufficient to accommodate the current and planned updates to our campus as outlined in our campus master plan.
