For our Greenhouse gas (GHG) inventories we used the date range of Columbia’s Fiscal Year (FY) which is September through August. Our GHG Baseline used FY10 data. This baseline did not include our location at 1600 S. State St. as it was then under construction. The location has since become occupied and operational and was included in our FY12 update. In FY12, Columbia purchased Renewable Energy Credits (REC) to offset 100% of our purchased electricity. These offsets account for the large change seen in FY12 net emissions.

Our updated inventory has shown a 0.3% reduction in emissions per FTE (Faculty, Staff and Students). This was at a time when the college saw reductions in both student enrollment and employed faculty and staff. There was also a 17.7% reduction in emissions per square footage while we saw an increase in our square footage on campus.

For all inventories, we used a carbon management and analysis platform through Clean Air Cool Planet to calculate our emissions. This web based calculator updated their methodology in 2012 specifically in how emissions from Purchased Electricity and Solid Waste were calculated. This accounts for increases in these two factors. All others emissions factors have seen reductions.

This reduction of 2,679 metric tonnes of CO2e is the equivalent of : Taking 560 passenger vehicles off the road Not producing 301,296 gallons of gasoline Not consuming 6,250 barrels of oil Electricity usage for 402 houses in one year In one year, not using 111,982 propane cylinders for barbeque grills This information was generated from an EPA resources calculator.
