The chart above shows transportation-based carbon dioxide emissions broken down by population in EU states.  Three states (Luxembourg, Denmark, and Malta) really stand out having at least 2.5 times the emissions that fourth place Ireland has.

The chart above shows transportation-based carbon dioxide emissions broken down by population in US states.  It is no surprise that Alaska where travel by bush plane is so common takes the top spot.

The chart above shows transportation based carbon dioxide emissions in EU and US regions.  Clearly, US regions emit far more transportation-based carbon dioxide than EU regions do.

The chart above shows transportation based carbon dioxide emissions in US regions.  The South is responsible for over two-fifths of transportation-based carbon dioxide emissions.

The chart above shows transportation based carbon dioxide emissions in EU regions.  Well over half the emissions in the EU come from the Western EU.

The chart above shows transportation based carbon dioxide emissions in EU and US states.  One-quarter of all carbon dioxide emissions from transportation use in the EU and the US come from four states (out of 78): Texas, California, Florida, and Germany.  In addition, Texas and California are the only two states that emit more than 100 million metric tons.

The chart above shows transportation based carbon dioxide emissions in US states.  One-quarter of all carbon dioxide emissions from transportation use come from three states: Texas, California, and Florida.

The chart above shows transportation based carbon dioxide emissions in EU states.  One-third of all carbon dioxide emissions from transportation use come from two countries: Germany and the United Kingdom, adding in France and Italy makes up more than half of the transportation based carbon dioxide emitted within the EU.
