Breathing Earth is an interesting web site that simulates carbon dioxide emissions as well as birth and death rates around the world. Hover over a point on the map and get the estimated statistics for that particular country. A running tab on the lower left hand calculates for the specific country and the lower right hand tabulates for the entire world :
Please remember that this real time simulation is just that: a simulation. Although the CO2 emission, birth rate and death rate data used in Breathing Earth comes from reputable sources, data that measures things on such a massive scale can never be 100% accurate. Please note however that the CO2 emission levels shown here are much more likely to be too low than they are to be too high.
