Your reference for that claim? Because our Government says that 7% of global CO2 emissions due to fossil fuels are attributed to U.S. transportation. The link below shows that transportation produces 34% of US CO2, while US CO2 is 21% of the world CO2; therefore 34% of 21% is 7% of world CO2 results from US transportation.
