Scope 1 and Scope 2 GHG emissions

Gross GHG emissions

Gross Scope 1 and Scope 2 greenhouse gas (GHG) emissions:
Performance year Baseline year
Gross Scope 1 GHG emissions from stationary combustion 6,264.73 Metric tons of CO2 equivalent 7,398 Metric tons of CO2 equivalent
Gross Scope 1 GHG emissions from other sources 261.85 Metric tons of CO2 equivalent 898.89 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported electricity 8,898.47 Metric tons of CO2 equivalent 12,260 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported thermal energy 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Total 15,425.05 Metric tons of CO2 equivalent 20,556.89 Metric tons of CO2 equivalent

Carbon sinks

Figures needed to determine net carbon sinks:
Performance year Baseline year
Third-party verified carbon offsets purchased 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 storage from on-site composting 33.52 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Carbon storage from non-additional sequestration 8.89 Metric tons of CO2 equivalent 1.47 Metric tons of CO2 equivalent
Carbon sold or transferred 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Net carbon sinks 33.52 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent

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

A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):
The university has three sources of carbon sinks associated with campus. The primary source is a large arboretum as well as over 3,700 mature trees. The latter is a wetland restoration project known as Bushy Lake that is a research based wetland focused on preservation with efforts led by Environmental Studies professor Dr. Michelle Stevens and countless students. Our extensive composting systems also acts as a carbon sink.

Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 15,391.53 Metric tons of CO2 equivalent 20,556.89 Metric tons of CO2 equivalent

Performance and baseline periods

Start and end dates of the performance year and baseline year (or three-year periods):
Performance year Baseline year
Start date July 1, 2018 July 1, 2013
End date June 30, 2019 June 30, 2014

A brief description of when and why the GHG emissions baseline was adopted:
The performance year was chosen based on the most recent 12 month fiscal period prior to starting work on the STARS report. The baseline year was determined by choosing the 12 month period prior to completing the first STARS assessment.

Part 1. Reduction in GHG emissions per person

Metric used in scoring for Part 2

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:
0.00 MtCO2e per square foot

A brief description of the institution’s GHG emissions reduction initiatives:
- carbon commitment signed in 2015 with second nature declaring a 2040 carbon neutrality goal
- a refined focus on integrating GHG emission reduction goals into sustainability staff's position description
- IPM strategic goals include increasing carbon sequestration through planting more trees and using campus generated compost
- Investment in a campus wide strategic energy plan to help outline future energy reduction projects

Examples of projects supported by above initiatives include:
- onsite composting of campus organic waste that includes both green and food waste
- lighting retrofit to LED and occupancy controlled buildings in Mendocino Hall and the library
- Integrating two and a half megawatts more of photovoltaic solar production for a total of 3 megawatts on campus of onsite generation
- a $700,000 grant funded project through the Department of Water Resources focused on reducing water energy and GHG emissions included replacement of such items as restroom faucets, kitchen faucets, shower heads, and various commercial kitchen appliances
