Band 8+: The line graph and the bar chart give the information and forecast about the vehicle numbers and CO2 emission in England and Wales between 2000 and 2020. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The line graph and bar chart illustrate the number of vehicles and the amount of CO2 emissions in England and Wales from 2000 to 2020. Overall, the number of vehicles steadily increased during this period, with cars being the largest contributors to CO2 emissions, while buses and trucks produced comparatively less.

The CO2 emissions from all types of vehicles remained relatively stable, despite the rise in the number of vehicles. According to the line graph, the total number of vehicles in England and Wales began at 20 million in 2000. It gradually rose to around 35 million by 2010 and continued to climb, reaching 60 million by 2020. The proportion of vehicles consistently increased over the entire period.

The bar chart highlights the contributions of different vehicle types to CO2 emissions. Cars had the highest emissions, accounting for approximately 2.5 tonnes in 2000, 2010, and 2020. Vans followed, emitting around 1.0 tonne, while both buses and trucks contributed less than 1.0 tonne throughout the period. These emission levels remained almost constant, even with the increase in the number of vehicles.
