The bar & line graph compare the amount of CO2 emitted from means of transport, and data on the number of vehicles respectively in England and Wales over a period of 20 years from 2000.

It is clear that the graphs showed an upward trend, with an exception for the amount of CO2 emission of bus , rising from 2000 to 2020. It is also noted that the CO2 emission of car was significantly higher than those of van and truck.

Looking at the bar chart, in 2000, the highest CO2 emission figure was seen in car (20 tons). The number of CO2 which was emitted by van and truck slightly increased, 13 tons and 15 tons respectively. Meanwhile, those of bus stabilised at 8 tons. A last year surveyed, the figure for CO2 emission of car, van and truck, increased to 26 tons, 15 tons, 15 tons respectively.

Of the line graph, in the period surveyed, the figure for vehicles showed a steady increase, rising by 20 tons each decade. They rocketed from the high point of 20 tons, hitting to the greatest point of nearly 60 tons.
