The given line graph illustrates data on the transportation number, while the bar chart gives information about carbon emissions in England and Wales from 2000 to 2020.
Overall, it can be clearly seen that the vehicle number observed an upward trend over a two-decade period, whereas the largest carbon emissions were produced predominantly by cars.
To begin, the number of vehicles stood at 20 million at the beginning of the given period, then this figure kept gradually increasing over the two decades. This indicator reached its peak of 60 million vehicles in 2020.
The maximum amount of carbon emissions was produced by automobiles between 2000 and 2020, rising from just over 2 tonnes to 3 tonnes of emissions. By contrast, the lowest contributor of CO2 emissions was trucks. This figure saw a slight increase from approximately 0.2 tonnes to just under 0.5 tonnes of emissions throughout the period given. While emissions produced by buses rose marginally, emissions from vans increased sharply over the two-decade period. These numbers climbed from 0.5 and just over 0.5 tonnes of greenhouse emissions to slightly above 0.5 and well over 1.5 tonnes of emissions in 2020.
