Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:

	Performance year	Baseline year
Adjusted net GHG emissions	23,685.40 Metric tons of CO2 equivalent	34,400.10 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	April 1, 2018	April 1, 2008
End date	March 31, 2019	March 31, 2009

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

The 2008/2009 baseline is used because this was the first year that NSCC began comprehensively tracking GHG emission data on a monthly basis for Scope 1 and 2 emission sources across all sites.

Part 1. Reduction in GHG emissions per person

Weighted campus users

Figures needed to determine “Weighted Campus Users”:

	Performance year	Baseline year
Number of students resident on-site	120	180
Number of employees resident on-site	0	0
Number of other individuals resident on-site	0	0
Total full-time equivalent student enrollment	12,703	9,976
Full-time equivalent of employees	1,845	1,633
Full-time equivalent of students enrolled exclusively in distance education	737	63
Weighted Campus Users	10,388.25	8,704.50

Metrics used in scoring for Part 1

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	2.28 Metric tons of CO2 equivalent	3.95 Metric tons of CO2 equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:

42.31

Metric used in scoring for Part 2

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

0.01 MtCO2e per square foot

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

Impact on GHG emissions is factored in to NSCC's capital planning decisions, to best leverage infrastructure renewal projects to reduce our emissions. Recently, we have replaced aging fuel oil fired boilers at Lunenburg and Burridge Campuses with high-efficiency propane units, and also replaced the fuel oil boiler at Pictou Campus with a high-efficiency natural gas unit. In addition, we are currently in the process of replacing the fuel oil boilers at Truro Campus with high-efficiency propane and wood pellet units.

NSCC is also addressing air leakage through envelope replacement when possible. Recent projects include a replacement of 73% of the building envelope system at Lunenburg Campus and partial roof replacements at multiple sites.

NSCC has completed ASHRAE Level 2 energy audits at all Campuses within the last five years. The most recent audits were completed at Luenenburg, Pictou, Truro and Marconi Campuses in 2019. We have also completed retro-commissioning studies at nine of our campuses in 2019. Between the capital suggestions in the energy audits, and the low-cost/no-cost suggestions in the retro-commissioning studies, NSCC Facilities were able to prepare Energy Management Plans for all campuses, which outline all potential energy-related projects, their associated costs and timeline for completion, as well as overall impact on NSCC's GHG emissions.

Data source(s) and notes about the submission:

Scope 1 and 2 emissions were calculated by NSCC Facilities management, based on heating fuel consumption, imported steam and electricity at all NSCC-owned sites. The data is compiled centrally and recorded in a historical database for historical comparison. Additionally, NSCC has now uploaded all of our current and historical fuel and electricity consumption data into Energy Star Portfolio Manager's online platform, which allows us to quickly calculate and compare yearly GHG emissions, as well as weather-normalized energy consumption data.

Business travel related GHG emissions were collected by requesting rental vehicle data from Enterprise Car Rentals, which is NSCC's primary rental vehicle associate. Enterprise provided a full GHG breakdown given NSCC's rentals throughout the fiscal year.
