A quantitative view of the carbon cycle
Ciais et al., 2013 Common Future, Paris, 2015, 2/15
Basic calculation
carbon dioxide emitted = fuel consumed * fraction of that fuel actually combusted * carbon content of that fuel
Common Future, Paris, 2015, 3/15
Basic calculation
carbon dioxide emitted = fuel consumed * fraction of that fuel actually combusted * carbon content of that fuel
Cement has an analogous equation to describe emissions from cement production:
CaCO3 -> CaO +CO2

Conclusions/Implications
1. FFCO2 emissions are a primary driver of the atmospheric disequilibrium impacting and changing other components in the global carbon cycle upon which modern day concerns of climate change are based.
2. FFCO2 emissions can be characterized in a variety of ways (e.g., fuel type, national totals, Kyoto Protocol status, geography, …).
3. In terms of global climate change concerns, it does not matter from which individual country emissions originated. It is the total quantity of CO2 in the atmosphere that is of ultimate concern to climate change processes.
