Here in America the last 3 years our CO2 output has declined, just a little, 1 or 2 %.  Good.  But we are now responsible for more, much more CO2 being released than ever before.  How?

We are digging up and exporting fossil fuel at a much higher pace.  Exporting coal to China, Diesel to Europe, refined gasoline to a number of countries, even liquid natural gas.  All this gets burned, it goes on their books as the source of global warming carbon, but it's ours, we are doing it.
