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 productionPurchased electricity TransportationWasteAgriculture Refrigerants

GHG Emissions at AUS

Baseline indicators: operating budget, energy budget, square-footage of the building and population of full time students, part time students, faculty, and staff.

Resources used by the people in the building including: annual tons of solid waste, purchased kilowatt hours of electricity, gallons of wastewater, and paper purchased.

Transportation methods of the students, faculty, and staff to and from AUS.
