Carbon Footprint Formula - Equation For Carbon Emissions
Emissions of greenhouse gases other than CO 2 = 100 ÷ 95 Gram to pound conversion = .0022 Air Travel CO 2 emissions in pounds = air miles traveled per year × (average direct emissions per air mile × indirect well-to-pump factor × indirect atmospheric radiative forcing factor) × gram to pound conversion Average emissions per mile = 223

Cement production is massive contributor to carbon dioxide
The result is that no carbon dioxide is released to the environment from the entire process, Chiang says. By contrast, the carbon dioxide emitted from conventional cement plants is highly contaminated with nitrogen oxides, sulfur oxides, carbon monoxide and other material that make it impractical to “scrub” to make the carbon dioxide usable.
