The given line graph depicts the number of vehicles in England and Wales from 2000 to the present time and also gives prediction upto 2020. The bar chart gives the information on the amount of Co2 emission by four different form of transport, which are cars, buses, vans and trucks over the same period.
Overall, vehicle numbers are expected to increase in future, and the Co2 emission are also expected to escalate in future.
There were nearly 20000 vehicles in England and Wales in 2000.Then, the total number went up slightly to 35 million in the following 10 years and is expected to experience a rapid upward tendency reaching around 60 million by 2020.
the column graph shows four primary sources of CO2 emission. Cars emitted the largest amount of C02 from 2000 to 2010 and this trend is predicted to continue and reach 3 tonnes by 2020. Interestingly, the trucks went through and forecast a similar trend as cars but the total amount is significantly less, from 0.6 tonnes in 2000 to 1.3 tons in 2020. The emission of C02 from buses and vans is likely to keep steady at around 0.4 and 0,6 tons respectively.
