Adjusted net Scope 1 and Scope 2 GHG emissions:
| Performance year | Baseline year | |
| Adjusted net GHG emissions | 600.37 Metric tons of CO2 equivalent | 476 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 | Jan. 1, 2019 | Jan. 1, 2008 |
| End date | Dec. 31, 2019 | Dec. 31, 2008 |
A brief description of when and why the GHG emissions baseline was adopted:
As a state agency, the Seattle Colleges (including North Seattle College) are required to report annual greenhouse gas emissions in compliance with the State Agency Climate Leadership Act. This act, passed in 2008, established greenhouse gas baseline dates and greenhouse gas reduction targets for all state agencies (2005 baseline for Seattle Colleges). However, we have set our GHG and energy baseline as 2008 for STARS considering the following; 1) this act was not passed until 2008, 2) we did not actively track or take any significant actions to mitigate our GHG emissions or utility usage until 2008, and 3) data reporting and tracking was not systematized until 2008. This will result in a more accurate and appropriate 2008 baseline.
Figures needed to determine “Weighted Campus Users”:
| Performance year | Baseline year | |
| Number of students resident on-site | 0 | 0 |
| Number of employees resident on-site | 0 | 0 |
| Number of other individuals resident on-site | 0 | 0 |
| Total full-time equivalent student enrollment | 3,485 | 3,912.20 |
| Full-time equivalent of employees | 483 | 491.30 |
| Full-time equivalent of students enrolled exclusively in distance education | 106.60 | 55.10 |
| Weighted Campus Users | 2,896.05 | 3,261.30 |
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:
| Performance year | Baseline year | |
| Adjusted net Scope 1 and 2 GHG emissions per weighted campus user | 0.21 Metric tons of CO2 equivalent | 0.15 Metric tons of CO2 equivalent |
Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:

A brief description of the institution’s GHG emissions reduction initiatives:
Seattle Colleges has set GHG emission reduction targets for 2020 (15% reduction), 2030 (45% reduction), 2040 (70% reduction), and 2050 (95% reduction), with a baseline of 2005 (3,995 MTCO2e) as mandated for WA State agencies.
Changed OCE&E boiler from gas to high efficient electric boiler.
Several North Seattle buildings participated and completed City of Seattle Building Tune Ups in 2019 (College Center, Instructional Building, Arts & Sciences, Library Building, Health Sciences and Student Resources (HSSR), and Opportunity Center for Employment & Education). These Tune Ups require buildings more than 50,000 square feet of non-residential space to identify and implement zero to low-investment energy-saving actions related to building operations and maintenance.
College Center- adjust building AHU-8 to run based on building usage. Replace faulty sensors.
Library- adjust morning start times on equipment to save energy. Fix or replace outside air dampers that do not fully close when commanded.
OCE&E- adjust morning start times on equipment to save energy. Fix or replace vestibule that is overheating.
Installed 4 new EV charger stations in early 2018.
Additionally, in early 2021, North underwent an Investment Grade Audit with an WA State approved Energy Service Company (ESCO) to identify more greenhouse gas emissions reductions opportunities. That assessment is being finalized in fall 2021 and we expect to start several energy and water efficiency projects as a result.
Lastly, North is applying for several grants to help fund a 96 kW solar PV system on campus.

Data source(s) and notes about the submission:
URL is for Seattle Colleges greenhouse gas summaries. NSC does not currently provide GHG summaries online, but they exist annually for 2005-2020.
CO2 numbers were derived using the Washington State Department of Ecology Greenhouse Gas Calculator and these numbers only include direct energy use emissions.

In 2005, Seattle City Light (SCL) became the first electric utility in the country to achieve zero net greenhouse gas emissions. SCL has maintained that carbon neutral status every year since. The portion of NSC CO2e emissions from electricity has verified offsets built in, but we use a custom electricity emission factor, which represents actual electric grid emissions before offsets. http://www.seattle.gov/city-light/energy-and-environment/environment/climate-change-and-energy
