Global Greenhouse Gas Data
Atmospheric concentrations of greenhouse gases are affected by the total amount of greenhouse gases emitted to and removed from the atmosphere around the world over time. Figure 1 shows a breakdown of global greenhouse gas emissions by each gas.

Figure 2 presents data on the major global sources of carbon dioxide (CO2) emissions by country, from the beginning of the Industrial Revolution to the present.

Subscribers to the World Resources Institute's Climate Analysis Indicators Tool (CAIT) can draw on existing greenhouse gas data to generate breakdowns of global emissions by year, country, source and greenhouse gas. In addition, the Intergovernmental Panel on Climate Change synthesizes existing scientific data on global fluxes of greenhouse gas emissions and removals in its assessment reports . These reports provide global data by gas and by type of emission pathway (e.g., general type of source or sink), and include both human and natural emissions.
Figure 3 provides a projection of future greenhouse gas emissions of developed and developing countries. Total emissions from the developing world are expected to exceed those from the developed world by 2015.
