World CO2 emissions 
from energy 
CO2 emissions by nation 
CO2 emissions by nation per capita.
This data from the US EPA gives an idea of the relative industrial nation
​ contribution to CO2 emissions from fossil fuels. 
For zero carbon emissions all CO2 sources matter.
  • Fossil fuel combustion                                          
    Industry, building utilities, transport
    Cement manufacture
  • Deforestation (Livestock food production)
  • Food production/agriculture (disturbing soil releases CO2)
  • Carbon feed backs (caused by global warming)

Sources by industry





C​arbon dioxide emissions by national quantities
Industrial scale deforestation is a major source of carbon dioxide.
​Most of the deforestation goes towards the raising of livestock.
This makes industrial food production a major source of carbon dioxide and methane​.
