On gallon turns into 172 cubic feet / 4.87 cubic meters of CO2.

1 ton of CO 2 takes up 19,000 cubic feet / 556 cubic meters space

Example: Width = 8.12 m Length = 8.12 m Height = 8.12 m Volume = 536 m³ Temperature = 15º C Pressure = 760 torr Weight = 1000 kg CO 2 GPS coordinates: North: 29º West: 082º Elevation: 64m Creating a Volumetric GPS Timestamp (VGT), or CarbonMap

Much reduction is needed to reach stability Human emission rate in billion t/C/yr t Equilibrium Latent atmospheric C is about 188 billion ton Emissions the earth absorbs in billion t/C/yr

To reduce local emissions by 20%, how much is it worth? How much does it cost? 3 MtCO2e x 20% x $15/tCO2e = $9 million for ~ 10 years = $90 million total 3.46¢/l or 16.25¢/gl 3 MMTCO2/yr = 41 km²/yr Alachua County = 2623 km² or 192,528,200 tCO2 maximum absorption or 63 years
