A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):

ACG is located within the natural boundaries of the Hymmetus mountain forest . Since its initial construction the institution has been committed to the maintenance of the forested area that covers 2/3 of the ACG total (15.6Ha). It has been calculated that the spruce forest amounts to a rate of sequestration approximating 12tC/Ha/Yr .


Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 2,385.46 Metric tons of CO2 equivalent 6,049.86 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, 2021 Jan. 1, 2019
End date Dec. 31, 2021 Dec. 31, 2019

Data source(s) and notes about the submission:

Total full-time equivalent student enrollment appears different from PRE 5 of the Demographics due to the nature of the institution which has a joint technical and operational facility with its secondary school division. All GhG emissions (including the inventory) have been measured and performed for the entire campus and operations (including those of Pierce college, our secondary education division) taking into account total student population (graduate, undergraduate and secondary education). The secondary education division of ACG caters for a population of 1,616 for students which explains the FTE derived number. For reasons of accuracy the joint number 3,284 and 1,616 was used to derive the adjusted emissions. Τhe numbers included here are for 2021 that is the reason the demographics entered here differ from PRE 5
