EES 306 Carbon Emission Projections. Projections to 2030. Quad. Btu is a basic unit of energy MBtu = 1 million Btu = 8 gallons gasoline Qbtu = 1 billion MBtu = 8 billion gallons gasoline Quad = 1 Qbtu = a quadrillion Btu Q stands for quadrillion and means a million billion.
Projections to 2030
C + O2 CO2CO2 Emission
Pre-Industrial value: 280 ppm (600 billion tons)
Current value: 380 ppm (800 billion tons)
Critical value: 560 ppm (1200 billion tons)
Growth in LDC wealth means raising more people in LDCs out of poverty. Greater wealth means greater use of fossil fuel energy and greater environmental impact. Can we break this link?
= Primary Energy Consumption/ GDP
= CO2 Emission/ Primary Energy Consumption
Energy Intensity x Carbon Intensity
9000 Btu/$ x 60 MMT/QBtu
= 6 billion Metric tons
