The graph and chart give information and forecast about the vehicle and CO2 emission in England and Wales between 2000 and 2020

The two figures show the information and prediction the number of vehicle and amount of CO2 emission in England and Wales from 2000 to 2020.
Firstly, at the graph, the largest amount of CO2 is come from cars which is 20 tons from 2000 and increase to 26 tons in 2020. Parallel with the increasing volume of CO2 emission from cars, the total CO2 from vans is gradually increase from 13 tons to 15 tons during 20 years and this number from trucks is rapidly rise 8 tons from 2000 to 2020. In contrast, buses' greenhouse gas is the smallest which is constantly under 10 tons for 20 years.
Looking at the line graph, the quantity of vehicles have increased from 20 million in 2000 and it is predicted to be more than 50 million automobiles in 2020.
To sum up, the graphs present us the boost in both number of vehicles and amount of CO2 gas except buses' CO2 mass.
