A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):

Each year, Colgate's Office of Sustainability and Sustainability Council publishes an annual Carbon Offsets report that details the university's process for purchasing offsets and the type and specific projects invested in. Colgate's 2021 annual offsets report can be accessed here: https://drive.google.com/file/d/1CdPzWCovpTdOxXOskdbFipHZaTvIVUSh/view?usp=sharing

Additionally, Colgate’s local forest has been certified by the American Tree Farm System for long-term sustainable management. These trees have been inventoried and sequester 3,778 tons of carbon dioxide annually. We actively manage these forests, as outlined in our land-stewardship plan. This plan has five goals: teaching and research; outdoor recreation and aesthetic value; conservation of ecosystems services and biodiversity; timber production; and carbon sequestration. We adhere to this plan to manage our forest for sequestration. More information and our forest carbon inventory can be found here: https://www.colgate.edu/about/sustainability/land-forest-stewardship

The elimination of Scope 2 (electricity) emissions between Colgate's baseline in 2009 and the performance year was due to the Hamilton Municipal Coop (the local utility that Colgate purchases electricity from) securing 100% of its power from carbon-free hydroelectricity and nuclear power within our state.


Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 1,906.56 Metric Tons of CO2 Equivalent 9,466.08 Metric Tons of CO2 Equivalent

Start and end dates of the performance year and baseline year (or three-year periods):
Performance year Baseline year
Start date July 1, 2020 June 1, 2009
End date June 30, 2021 May 30, 2010

A brief description of when and why the GHG emissions baseline was adopted:

Our baseline was established with the hiring of our Director of Sustainability and with our first greenhouse gas inventory after signing the American College and University Presidents' Climate Commitment (since renamed Second Nature's Climate Commitment) in 2009. Before this, Colgate did not measure the university's greenhouse gas footprint (comprehensively).

A brief description of the institution’s GHG emissions reduction initiatives:

In 2009, we signed the ACUPCC (Second Nature's Carbon Commitment) and committed to carbon neutrality by 2019 with the final approval of our 2011 Sustainability and Climate Action Plan. The Plan identified 27 carbon mitigation projects that we have been implementing systematically. To date, we have installed solar thermal and geothermal energy systems, replaced fuel oil #6 with natural gas, built and renovated six buildings that have achieved LEED certification, completed energy conservation measures in our existing buildings (e.g., HVAC upgrades, variable speed drives, LED lighting upgrades, etc.). We have installed electric vehicle charging stations, purchased hybrid and electric vehicles for our vehicle fleet, installed low-flow showerheads throughout campus, introduced an on-campus composting program, expanded our bike share program, introduced student and staff educational programming, among others. As a result of these actions, the university has reduced its carbon footprint by over 50 percent since 2009 despite adding five new buildings and over 100 additional students, faculty, and staff.
