Shows various countries and their levels of CO2 emissions per capita. Also indicates the difference from high income to low income nations on CO2 output. Central to any study of climate change is the development of an emissions inventory that identifies and quantifies a country’s primary anthropogenic sources and sinks of greenhouse gas. Emissions are not usually monitored directly, but are generally estimated using models. Some emissions can be calculated with only limited accuracy. Emissions from energy and industrial processes are the most reliable (using energy consumption statistics and industrial point sources). Some agricultural emissions, such as methane and nitrous oxide carry major uncertainties because they are generated through biological processes that can be quite variable.
