"---" indicates that no data was submitted for this field

Part 1 

Has the institution conducted a GHG emissions inventory that includes all Scope 1 and 2 emissions? :
Yes

Does the institution’s GHG emissions inventory include all, some or none of its Scope 3 GHG emissions from the following categories?:
All, Some, or None
Business travel All
Commuting All
Purchased goods and services Some
Capital goods None
Waste generated in operations All
Fuel- and energy-related activities not included in Scope 1 or Scope 2 Some

A copy of the most recent GHG emissions inventory:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory, including how the institution accounted for each category of Scope 3 emissions reported above:
From 2008-2016, the university worked with a consultant using Clean Air-Cool Planet’s Campus Carbon Calculator to measure campus emissions. Staff and students were responsible for gathering data from various campus departments. This audit is now done internally, with campus departments reporting data to the Sustainability and Energy Coordinator in Facilities Management. The university is now using the SIMAP tool from the University of New Hampshire.

Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:
Yes

A brief description of the internal and/or external verification process:
A graduate assistant working with Facilities Management, but independent of the GHG accounting process, validated and verified the process, assumptions, and calculations.

Documentation to support the internal and/or external verification process:
---

Does the institution wish to pursue Part 2 and Part 3 of this credit? (reductions in Scope 1 and Scope 2 GHG emissions):
Yes

Part 2 

Gross Scope 1 and Scope 2 GHG emissions:
Performance Year Baseline Year
Gross Scope 1 GHG emissions from stationary combustion 15,702.53 Metric tons of CO2 equivalent 12,785.16 Metric tons of CO2 equivalent
Gross Scope 1 GHG emissions from other sources 508.67 Metric tons of CO2 equivalent 524.78 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from purchased electricity 49,273.51 Metric tons of CO2 equivalent 47,384.74 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from other sources 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Total 65,484.71 Metric tons of CO2 equivalent 60,694.68 Metric tons of CO2 equivalent

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year July 1, 2016 June 30, 2017
Baseline Year July 1, 2008 June 30, 2009

A brief description of when and why the GHG emissions baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
For energy and emissions, we chose 2008-2009 baseline because that year we have records of electricity and natural gas for all major accounts. In 2011, our baseline for water and waste, we only have electricity and natural gas annual data from a different and less trusted data source that does not specify the included accounts.

Figures needed to determine total carbon offsets:
Performance Year Baseline Year
Third-party verified carbon offsets purchased (exclude purchased RECs/GOs) 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Institution-catalyzed carbon offsets generated 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Carbon sequestration due to land that the institution manages specifically for sequestration 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Carbon storage from on-site composting 19.20 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Carbon offsets included above for which the emissions reductions have been sold or transferred by the institution 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Net carbon offsets 19.20 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent

If total performance year carbon offsets are greater than zero, provide:

A brief description of the offsets in each category reported above, including vendor, project source, verification program and contract timeframes (as applicable):
Dining Services has a composting program where pre- and post-consumer food scraps and paper materials are collected and sent to a commercial composting facility in the area.

The reporting fields in the table below are reserved for institutions that have NOT already accounted for renewable energy purchases (including RECs and GOs) in their Scope 2 GHG emissions calculations. Other institutions - including all SIMAP users - should report zero ('0') to avoid double-counting. 

Emissions reductions attributable to Renewable Energy Certificate (REC) or Guarantee of Origin (GO) purchases:
Performance Year Baseline Year
Emissions reductions attributable to REC/GO purchases 566.29 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent

A brief description of the purchased RECs/GOs including vendor, project source and verification program:
The university purchased 828 MWh of renewable energy in FY17. They are Green-e certified wind RECs from Schneider Electric.

Adjusted net Scope 1 and 2 GHG emissions:
Performance Year Baseline Year
Adjusted net Scope 1 and 2 GHG emissions 64,899.22 Metric tons of CO2 equivalent 60,694.68 Metric tons of CO2 equivalent

A brief description of the institution’s GHG emissions reduction initiatives, including efforts made during the previous three years:
UD is a signatory of Second Nature and the We Are Still In commitment. UD has a Green Revolving Fund that is used to fund energy efficiency projects on campus. It has been heavily utilized by energy management staff and has funded projects initiated outside of operations by faculty and student community members. The newly formed Campus Energy Team, composed of undergraduate and graduate students, and staff from Facilities Management, has set a team goal of reducing scope 1 and scope 2 emissions by 26% by 2025 - in line with the United States INDC to Paris. So far they have audited a representative sample of academic buildings, residence halls, and athletic facilities in order to identify potential large-scale energy efficiency projects in lighting and HVAC controls. https://www.udayton.edu/artssciences/ctr/hsi/projects/energyteam.php In the last year UD worked with the electric utility and a local engineering firm on a retrocommissioning in our Science Center, one of our biggest energy users. These projects have focused on HVAC controls due to their large energy savings and low upfront capital cost. The project was successful and we will be working with them again on a retrocommissioning project at Fitz Hall this year.
