What the listing says

Returns carbon dioxide emissions for one or more countries on three bases at once: per inhabitant, per unit of purchasing-power-adjusted output, and in absolute megatonnes, each with its own period and its trend over the requested window. Keeping the three apart is the point. Per capita answers how heavily a person there burdens the climate; per unit of output answers how efficiently value is produced; absolute answers what actually reaches the atmosphere.
