Climate Change Impacts and Trends

2012-13 GHG Emissions

GHG emissions from 07-08 through 12-13

Greenhouse Gas Inventory

As part of the College's commitment to sustainability, Pomona is committed to annually tracking greenhouse gas emissions and to planning mitigation efforts to reduce those emissions. The College's inventory effort contains two groups of emissions - those we take responsibility for and include in our commitments and plans for emissions reduction, and others that we can measure that are associated with campus activity but which are not included in College planning. Energy use - including heating and cooling spaces, lighting, appliances, and many other activities - constitutes the largest part of the campus' greenhouse gas emissions and is the primary focus for reducing emissions.

As part of the College's membership in the American Colleges and Universities Presidents Climate Commitment, the Sustainability Integration Office and PACS maintain emissions reductions goals as part of the Sustainability Action Plan. See Climate Action Plan for more information. 

2012-13 Greenhouse Gas Inventory

The following emissions occurred in the 2012-2013 academic year. All emissions are measured in metric tonnes of carbon dioxide equivalent (mTCO2e), which is a measure used to compile a variety of greenhouse gases. The table below depicts the emissions described in the first chart, above.

*Note

The campus carbon calculator by Clean Air Cool Planet has made several revisions since Pomona began tracking. All past data has been recalculated in the current version (v6.9).

Emissions Trends

The following table includes emissions for the 2010-11, 2011-12, and 2012-13 academic years. The second image above graphs these emissions along with those for the 2007-08, 2008-09, 2009-10 academic years.
