Breakdown of total global greenhouse gas emissions (CO2 equivalent) by sector (left) and end use (right). Because of rounding, columns do not total 100%, and some emissions sectors at left contribute to more than one end use at right.(Adapted from World GHG Emissions Flow Chart 2010, World Resources Institute, wri.org.)
This schematic from Ken Caldeira and colleagues shows the largest international flows of emissions embodied in trade between major partners as of 2004, with nine western European nations considered as a group. (Steven J. Davis and Ken Caldeira/PNAS)

Trends in CO2 emission intensities for the top five emitting countries. The size of each circle represents total CO2 emissions from the country in that year. The location of each circle reflects energy use per capita (increasing from left to right) and energy use per dollar GDP/PPP (increasing from bottom to top). (International Energy Agency)
