Oxygen captured by CO2 emissions is 0.727 times the gross CO2 emissions figure. This is
the ratio of the atomic weight of O2 to CO2.
Greenland ice loss: 165 billion metric tons/year is from
NASA's web page Greenland's Ice Island Alarm.
("As data for additional years has become available all the NASA research community’s estimates
are converging toward an average annual net loss of ice mass loss of 150 to 180 gigatons per year.")
US VMT (vehicle miles traveled): 2,915,454 million is the 12-month moving
total in the US Dept. of Transportation's
April 2009 report.
US CO2 avoided (wind, hydro, solar): The CO2 emissions from energy sources
besides these three are used to pro-rate the savings. The numbers are from
Table 8.2a of
the Annual Energy Review 2008.
Airline passenger miles: 810,098 US airline domestic and international airline
passenger miles traveled/year (2006) is from Table 9.2 of the
Transportation Energy Data Book 27.
US liquid fuels consumed in lawn and garden equipment: 2,800,780,000 gallons
is from Table 2.10 of the
Transportation Energy Data Book 27. This figure
includes gasoline, diesel, and LPG, although it is about 90% gasoline.
