Sample Answer

The line graph shows the number of vehicles in England and Wales from 2000 to 2020, while the bar chart illustrates CO2 emissions from different types of transport over the same period.

Overall, the rising number of vehicles is linked to escalating CO2 emissions, particularly from cars and trucks, while emissions from buses and vans are predicted to remain stable.

The number of vehicles increased steadily from 20 million in 2000 to 35 million by 2010 and is forecast to climb sharply to 60 million by 2020.

The bar chart highlights cars as the largest contributor to CO2 emissions, with emissions rising from 2 tonnes in 2000 to a predicted 3 tonnes by 2020. Trucks follow a similar upward trend, increasing from 0.6 tonnes in 2000 to 1.3 tonnes by 2020. In contrast, CO2 emissions from buses and vans are expected to remain steady throughout the period, at 0.4 and 0.6 tonnes, respectively.
