Gross Scope 1 and Scope 2 greenhouse gas (GHG) emissions:
Performance year Baseline year
Gross Scope 1 GHG emissions from stationary combustion 62,441 Metric tons of CO2 equivalent 35,987.10 Metric tons of CO2 equivalent
Gross Scope 1 GHG emissions from other sources 9,909.30 Metric tons of CO2 equivalent 9,380.90 Metric tons of CO2 equivalent

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

Offsets are from ASU's Carbon Project: https://cfo.asu.edu/carbon-project

ASU has worked with the cities of Phoenix, Scottsdale, and Tempe to plant trees in locations such as community parks - combining carbon removal with urban heat island mitigation. These trees are periodically inventoried with a GIS tool to ensure they are still alive and growing. Through our previous relationship with Urban Offsets, ASU bundled these trees with offsets verified under the Verra protocol.

Note that Gross Scope 2 GHG emissions from imported electricity are reported as 0 due to purchased electricity being matched with RECs (see "Clean and Renewable Energy" for more information).


Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 0 Metric tons of CO2 equivalent 208,472 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 July 1, 2020 July 1, 2006

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

FY07 (July 1, 2006 - June 30, 2007) was the first year that Arizona State University issued a greenhouse gas inventory.
