CSU Climate Action Plan

CSU completed it’s first Climate Action Plan (CAP) in September 2010. The Climate Action Plan outlines how and when CSU will achieve climate neutrality. The CAP is considered a “living document” and is reviewed and updated every few years by a sub-committee of the CSU President’s Sustainability Commission.

About the Plan

Defines how and when CSU will work toward climate neutrality
Serves as a living document reviewed and updated over time
Supports public transparency through published plans and progress materials

CSU Greenhouse Gas Inventories

CSU compiles annual greenhouse gas inventories to track progress toward carbon neutrality. Inventories include all Scope 1 and Scope 2 emissions and a subset of Scope 3 emissions as required for reporting.

Definitions & Methodology

Fiscal year (FY) at CSU begins July 1 and ends June 30. The greenhouse gas inventory includes Scope 1 and Scope 2 emissions and a subset of Scope 3 emissions. Earlier inventories used the Campus Carbon Calculator, while CSU later transitioned to SIMAP.

CSU Nitrogen Footprint

CSU’s nitrogen footprint tracks nitrogen emissions from university sources and builds on greenhouse gas inventory inputs while incorporating additional campus data, including food procurement and operations.
