The line graph compares the number of vehicles, while the bar graph compares the amount of carbon dioxide emitted by four different forms of transport in England and Wales from 2000 to 2020.
Overall, it can be seen that the number of vehicles increased gradually. In contrast, cars had the highest level of carbon dioxide emissions over the given period..
From the line graph, in 2000, the number of vehicles was the lowest, at 20 million in England and Wales. In the following years, the figure increased gradually and reached its peak at 60 million by 2020.
In terms of the bar graph, it shows the amount of carbon dioxide emissions from four types of transport in 2000. Cars produced the highest amount of carbon dioxide emissions, at around 2.3 tonnes, followed by buses at approximately 0.3 tonnes. Vans accounted for 0.5 tonnes, while the figure for trucks was around 0.7 tonnes. From 2010 to 2020, the figures showed a similar trend. The carbon dioxide emissions from buses and vans remained unchanged at 0.4 and 0.6 tonnes, respectively. The amount of carbon dioxide emissions from cars and trucks increased gradually, from 2.6 and 0.8 tonnes in 2010 to 3 tonnes and 1.4 tonnes in 2020, respectively. Band score
