CWU 2022 Greenhouse Gas Inventory – Scope 1 and 2 Emissions
CWU’s 2022 greenhouse gas (GHG) inventory highlights the primary sources of carbon dioxide and methane emissions from the buildings, infrastructure, vehicles, diesel powered generators, and aviation program owned by CWU. Natural gas consumption, diesel powered generators, aviation, and fleet/business travel all fall under Scope 1 emissions. Scope 2 emissions include purchased electricity. Approximately 95% of CWU’s Scope 1 and 2 emissions are attributable to heating, cooling, and powering campus-owned infrastructure, revealing which sectors should be listed as priorities for decarbonization. This 2022 GHG inventory does not include Scope 3 emissions. Scope 3 emissions can be attributed to material waste generated on campus being sent to the local landfill, upstream/downstream emissions associated with goods and services, and commuter emissions (e.g. staff, students, and faculty commuting round trip to campus with internal combustion vehicles). There are currently 15 categories listed under Scope 3 emissions, which are the most difficult to measure and control. This CAP includes three Scope 3 emission categories: waste, commuter emissions, and procurement as a result of the feedback received from the campus community. The remaining Scope 3 emission categories will be addressed utilizing SIMAP software and will be included in overall sustainability strategic planning at CWU between 2024 and 2025.
