The given graph shows the nitrogen oxide emissions produced by four vehicles. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The given linear graph elucidates various speeds with the nitrogen oxide emitted by four different means of transport, which are

buses

,

lorries

, petrol

cars

and

diesel

cars

. The vertical axis of

this

graph stands for

while

the horizontal axis represents

. As can be seen from the graph,

buses

and

lorries

took the largest percentage of nitrogen oxide emissions, meanwhile, petrol and

diesel

cars

were more environmental-friendly.
