The image presents three charts: a line chart titled "Number of HGVs on US roads (in million)" shows approximately 5.8 million in 1990, 6.2 million in 1995, 8.0 million in 2000, 9.2 million in 2005, and 11.0 million in 2010; a bar chart titled "Carbon emitted by means of transportation for goods (in MMT CO2)" for 1990 and 2010 shows HGV emissions at ~230 and ~395, Ships at ~48 and ~40, Trains at ~35 and ~40, and Airplanes at ~105 and ~125 respectively; and a second line chart titled "Fuel used by HGVs in the U.S. (in TBtu)" indicates levels of ~13,000 in 1990, ~15,000 in 1995, ~16,500 in 2000, ~17,000 in 2005, and ~17,000 in 2010.

The provided charts illustrate the situation in number of Heavy Goods Vehicles and the amout of fuel used by them in US in time range from 1990 to 2010. There is also information on the amount of carbon emitted in 1990 and 2010 categorized by the type of vehicle.
Overall, the evidence shows the rising trend in the HGVs usage along with the increasing amount of used fuel. Therefore, the amout of emitted carbon also accounts a significant increase.
The number of HGVs on the US roads increased in about 2 times from just above 5 million to just above 10 million. However, the change in the amount of fuel is not that significant. It accounts for around 12500 TBtu in 1990 and for around 17500 Tbto, which is less than a third. The sharp rise in the amout of carbon emitted by HGVs is also obvious as it shows almost a 2 time increase, while other types of transport used for goods logistic had a minor increase or even a decrease, like data for ships show.
