Band 8: Task 1: (Line Graph) Differing amount of nitrogen oxide by four types of vehicles. (User-Written IELTS Writing Task 1 Sample)

The line graph highlights how many grams of nitrogen oxide emissions per kilometer are produced by four motor vehicles at their different speeds.

Across all speed ranges, overall, buses emit more of such gases in comparison to other vehicles on the list. It is also notable that the lowest amount of nitrogen oxide is released by diesel cars.

In detail, once buses reach a speed of 10 kph they release 40 g/km of NOx. Up to 60 kph, these gas emissions produced by buses keep reducing per speed before accounting for just over 25 g/km. From this speed and on, however, the more buses accelerate the more nitrogen oxide is emitted, and at 130 kph, which is the highest speed in the graph, buses produce around 43 g/km of NOx gasses.

Furthermore, the production of nitrogen oxide by lorries goes down from about 33 g/km at 10 kph to 18 g/km at 90 kph. Notably, the quantity of NOx emissions lorries release at 50 kph and 130 kph is the same (25 g/km). While nitrogen oxide emitted by petrol cars amounts to almost 10 g/km regardless of the speed, for diesel cars it is 5 g/km at any speed, excepting for 10 kph (7 g/km).
