GREENHOUSE GAS EMISSIONS INVENTORY REPORT 2009 Antioch University Seattle

What is a Greenhouse Gas Emissions Inventory? An accounting of the amounts and sources of emissions of greenhouse gases. The inventory provides a benchmark for our efforts to reduce GHG emissions. The completion of the inventory is part of the Climate Action Plan

Clean Air-Cool Planet Campus Carbon Calculator A massive spreadsheet to input the amounts and sources of greenhouse gas emissions both on campus and in activities associated with AUS. This tool was developed at the University of New Hampshire and adopted by the ACUPCC as the primary carbon calculator for institutions developing Climate Action Plans. Used by over 1200 institutions nationwide.

What is included in the calculator? The major categories are On-campus energy production Purchased electricity Transportation Waste Agriculture Refrigerants
