The line graph illustrates the forecast number of vehicles and the bar chart compares the amount of CO2 emission from different modes of transport in England and Wales from 2000 and 2020.
It can be seen that there was an upward trend in total annual vehicle number and the amount of CO2 emissions released from four means of transport in two countries during the period. Additionally, the amount of emission for cars was the highest while the opposite was true for vans in three given years.
With regard to the line graph, the figure for annual vehicle number in 2000 started at 20 millions, followed by a slight increase by 10 millions over the next 5 years. In 2010, there was a gradual growth to 35 millions in the total vehicle numbers before experiencing a significant rise to 50 millions in 2015. At the end of the period, the number of vehicles increased considerably and reached a peak of 60 million.
As can be seen from the bar chart, the amount of CO2 emission from cars was the highest number, starting at 2,25 tonnes, followed by a gradual increase from 2,75 tonnes to 3 tonnes over between 2010 and 2020. The figure for trucks was much lower, at only a quarter of that of cars, at about 0,6 millions, compared to 0,5 tonnes emission from vans in 2000. Then, the amount of emission from trucks experienced a sharp growth to 1,25 tonnes over the next 20 years, while the figure for vans increased slightly to 0,75 millions before decreasing by 0,1 tonnes in 2020. Additionally, only about 0,25 tonnes emission was released from buses, being the lowest figure, followed by a slight increase to approximately 1 tonnes and continuing to remain stable at this level at the end of the period.
