Middlebury Institute of International Studies at Monterey

Track the Institute's progress in creating a carbon neutral campus.

As part of its commitment to students, faculty, and the general public, the Institute publishes summary statistics of its sustainability efforts. Here you can find information on the Institute's greenhouse gas and waste audits. These statistics serve as a tracking device for you. Every year we continue to work towards our goals to further reduce greenhouse gas emissions and non-recyclable waste. Below are the results from our FY 15-16 audit. 

Greenhouse Gas Audit

Every year, the Institute conducts a greenhouse gas audit of Institute facilities and Institute-related activities. Conducting annual greenhouse gas audits helps the Institute to monitor progress in reducing emissions and determine a quantity of offsets necessary for carbon neutrality.

FY1516 Total Emissions

Since the first audit in 2006, the Institute considerably reduced its carbon footprint. In FY 2006-07, greenhouse gas emissions associated with the Institute were equivalent to the emissions from 718 passenger vehicles driven for one year. In FY 2015-16, the Institute's travel carbon footprint dropped to equal the equivalent of emissions from 341 passenger vehicles driven for one year.   

Emissions by Source 2015-2016

Emissions resulting from the Institute's travel remain the largest component of the campus footprint. This is a major challenge that is currently being addressed by the Sustainability Council. More details about our campus improvements to mitigate our greenhouse gas emissions can be found in the "Carbon Neutrality" section of our "Current Initiatives" webpage.

Campus Waste

The Institute is committed to minimizing waste and increasing recycling whenever possible. The Sustainability Council continuously monitors, documents, and tracks the progress of weekly campus waste output. Our 2015-2016 waste metrics were as follows:

  • Average Weekly Waste: 1,297 lbs.
  • Average Waste Recycled Weekly: 599 lbs.
  • Average % Waste Recycled Weekly: 46%


On July 1, 2010, the Institute officially merged with Middlebury to become a Graduate School of Middlebury College. Accompanying the merger, the Institute set a goal of recycling at least 40% of its waste. At 46% waste recycled weekly, we reached out recycling rate goal! However, we are not stopping here. We will continue to work with students, staff, and faculty to ensure that this upward trend continues into the coming year. In addition, we are also working on increasing our composting capacity - stay tuned for more news soon!

Battery recycling 

Since February 2008, the Institute has been collecting used batteries in special recycling bins throughout campus.  To date, the Institute has recycled over 2,250 pounds of batteries!
