Measuring & Reporting Dickinson's Emissions
Dickinson measures and reports its greenhouse gas (GHG) emissions annually to Second Nature’s President’s Climate Leadership Commitments (formally the American College and University Presidents Climate Commitment (ACUPCC)) and the Association for the Advancement of Sustainability in Higher Education’s (AASHE) Sustainability Tracking, Assessment and Reporting System (STARS). We measure and report our GHG emissions in order to prioritize our Climate Action Plan projects and meet our Climate Neutral by 2020 commitment. We will announce this accomplishment on April 22, 2020!
Dickinson categorizes greenhouse gas emissions into six major categories, Scopes 1, 2, and 3, gross emissions, offsets, and net emissions. Scope 1 emissions are those associated with activities the institution directly controls and manages (e.g., fuel consumption in the Central Energy Plant (CEP)), Scope 2 emissions are those associated with purchasing electricity from the grid, and Scope 3 emissions are those associated with College activities that produce emissions, but that the College does not directly control emissions reductions efforts (e.g., employee commuting and air travel). Gross emissions are the sum of Scope 1, 2, and 3 emissions. Offsets are reductions in emissions by others that are enabled by actions of the College, e.g., purchasing Renewable Energy Certificates. Offsets are subtracted from gross emissions to calculate our net emissions.
We are constantly working to improve our greenhouse gas accounting methods and have focused on estimating emissions from employee commuting and college travel more accurately. The new methodology are highlighted in the full report, and explain changes in past data summaries.
Dickinson College’s 2018 greenhouse gas emissions were 16,855 MT eCO2 gross and 10,316 MT eCO2 net (Fig. 1). Dickinson’s 2018 gross and net emissions were 272 MT eCO2 and 803 MT eCO2 more than 2017 gross and net emissions. Dickinson’s gross GHG emissions declined from the 2008 baseline level of 18,847 MTCO2E to 16,855 MTCO2E in 2018, a reduction of nearly 2,000 MTCO2E or 10.6%. Purchases of Renewable Energy Credits and composting of food waste at the Dickinson Farm offset a portion of the college’s gross emissions and reduce net emissions of GHGs. Net emissions (gross emissions minus renewable energy credits and offsets) decreased from 14,893 MTCO2E in 2008 to 10,316 MTCO2E in 2018, a decline of 30.7%.

Overall, our reductions in emissions have moved us toward our climate change commitment, which calls for a 25% reduction in gross emissions from our 2008 baseline by the year 2020. A variety of projects are in process or planned to meet our commitment, including replacing nearly all of the College’s lights with LEDs and the development of a 2.9 MW solar electricity facility that will supply approximately 30% of Dickinson's electricity consumption beginning in early 2019. The decrease in emissions occurred despite a 13.7% increase in Dickinson’s gross square feet of building space and a 1.9% increase in Dickinson’s population of students and employees over the 2008 – 2018 period. Countervailing the effects of these factors on GHG emissions are Climate Action Plan projects that increased energy efficiency, as reflected in a 9.8% decrease in energy use per square foot of building space; shifts in electricity generation in Dickinson’s market region that reduced carbon dioxide emissions per kilowatt hour (kWh) of electricity by 21.6%; and improved efficiencies in commercial air travel that reduced emissions per passenger mile by 16.1%.
For Dickinson’s 2018 gross emissions were, Scope 2 accounted for the largest percentage, followed by Scope 1 then Scope 3 (Fig. 2). Dickinson’s 2018 Scope 2 emissions accounted for 6,502 MTeCO2, or 38% of gross emissions, Scope 1 emissions accounted for 5,334 MT eCO2, or 32% of gross emissions, and Scope 3 emissions accounted for 5,019 MT eCO2, or 30% of gross emissions.
