Gasoline is 85.5% carbonGasoline is 85.5% carbon
1 gallon of conventional gasoline becomes172 cubic feet / 4.87 cubic meters of CO2
125 gallon makes one ton CO125 gallon makes one ton CO22
1 ton of CO2 easily fills up a 19,866 cubic feet / 556 cubic meters container
10 ton CO10 ton CO22 fills fills Florida Field 3 foot highFlorida Field 3 foot high
Every year, the United States produces 20 tons of CO2 per person
Humans add about 3 billion tC to the Humans add about 3 billion tC to the atmosphere each yearatmosphere each year
Notice the air over the Tibetan Plateau is very clear.
Most of this air pollution comes from human activities.
These particles impact local health, the region's hydrological cycle and average climate.

Global Climate ChangeGlobal Climate Changechanges everythingchanges everything
More CO2 changes plant behavior
More CO2 increases temperature of the atmosphere, the the earth’s crust and the oceans
Global hydro cycle; rain and moisture

These maps show the projected increase in average daily July heat index relative to the present. The largest increases are in the southeastern states, where the Canadian model projects increases of more than 25°F.
For example, a July day in Atlanta that now reaches a heat index of 105°F would reach a heat index of 115°F in the Hadley model, and 130°F in the Canadian model.

- Average temperature increase of 5 ~10°F
- Reversal of summer-wet, winter-dry
- Vectors
- Sea level rise

Expected sea level increase 21st Century:+ 1.2 meter
Florida + 5 meter, unavoidable w/out action

Achieving carbon-neutrality (the switch to clean energy) = 30 years?
Absorption of latent carbon (sequestration) = 7% of planet surface & 150 years?
CY 2001 UF GHG Profile - 519,623 tCO2

Annual school budget vs electrical:
- UM 470m / 6m = 1.3%
- UF 1,857m / 26m = 1.4%
- UCF 578m / 9m = 1.6%
UF is planning 16% growth over the next 10 years..
What are the dollar savings if all new buildings are Green?
$1,743,000 per year
And CO2 savings over the building lifetime?
2,100,000 tCO2
