Estimates of 'unavoidable offsets'

St. Lawrence University will be unable to reach climate neutrality (zero-net greenhouse gas emissions) without using offsets.  This spreadsheet uses 2011 greenhouse gas emissions data to estimate the number of metric tons of offsets the University would need to purchase or generate each year to reach zero emissions.  This spreadsheet also provides a ‘back of the envelope' calculation of the number and cost of using energy efficiency retrofits of North Country homes as an offset.
