The line chart provides information about the number of vehicles in England and Wales from 2000 to 2020. The graph gives data about the amount of CO2 emission and is divided into four categories: cars, buses, vans, and trucks.
At first glance, the amount of motor vehicles in England and Wales has noticeably increased from 20 million in the year 2000 to 60 million in 2020. As a result, the emission of CO2 has also escalated overall. Additionally, cars have always been the highest releaser of CO2, with a rising constant from 2.3 tons to 3 tons for 2 decades. Furthermore, trucks are the second-highest emitter of CO2, growing from 0.8 tons to 1.8 tons during these 20 years. Buses and vans have also shown an upward trend, discharging 0.5 and 0.7 tons of CO2 in the year 2020 respectively. While the emission of CO2 from vans remained the same between 2010 and 2020.
To sum up, the emission of CO2 is directly affected by the increasing number of vehicles from 2000 to 2020.
