Topic: The graph below shows different sources of air pollutants in the UK from 1990 to 2005. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

Model Answer 1:

The graph shows significant air pollution sources in the UK between 1990 and 2005.

Overall, there has been a gradual decline over the years in the amount of air pollution annually with the only exception in the transport sector which shows a rise.

In 1990, the industrial sector was the major emitter of air contaminants in the UK, with nearly 6 million tonnes. Together with other industries, the total amounted to about 8 million tonnes. The transport sector and household each were at the same level of 1 million tonnes in a year.

Over the next fifteen years, the total amount of pollutants discharged in the air decreased gradually to 5 million tonnes, a total decrease of 2 million tonnes approximately. Besides, this was achieved because the industrial sector also showed a reduction in their emission rate annually. In 2005 this amounted to only 2 million tonnes, a total decrease of about 4 million tonnes. However, there is a divergence in the rate of air pollution when the household sector and the transport sector are considered together. Households in the UK remained stable in their emittance rate from 1990 to 1999 at 1 million tonnes. However, since the year 1999, it dropped sharply to absolute zero in 2005. On the other hand, the transport sector since 1999 has increased with a rapid jump to 3 million tonnes in 2005.

Model Answer 2:

The given graph lists the four sectors in the UK and their respective emitted amount of air contaminants in the UK between 1990 and 2005. The measurements are given in million tonnes, and the four differently coloured lines denote four different sectors: total amount, industry, transport, and household.

If the overall is considered, we can see a decline in the total weight of air pollutants from 1990 to 2005.

According to the above graph, in the year 1990, the industrial sector contributed to air pollution the most. It is sustained by emitting air pollutants up to 6 million tonnes. At the same time, the transport sector and the households in the UK were at the same threshold of only 1 million tonnes. With a bit of a hiccup in the transport sector, it remained at 1 million along with the household sector till 1999.

The next fifteen years saw a significant decline in the total emitted air pollutants, and it continued to decrease to 5 million tonnes annually in 2005. Hence, the difference in the number of air pollutants emitted is 2 million tonnes. In terms of the sector, the industry offered a significant change with a decline of 2 million tonnes in 2005 from back in 1990 which was about 6 million tonnes. Additionally, households in the UK achieved the zero-emission goal in 2005 after remaining stable over a significant period of the considered fifteen years period. The decline started in 1999.

On the contrary, it is the transport sector which in 1999 jumped up exponentially in the number of air pollutants released in the atmosphere. In 2005 it stood at 4 million tonnes.

Model Answer 3:

The line graph depicts the annual emissions released into the atmosphere from various sources over a period of fifteen years. The same also shows an aggregate of the total amount of emissions over the said period.

In all, the amount of air pollution by the industrial sector is much higher than the other sources placed on the graph's x-axis. If the total is considered, we can also see an overall decrease in the total amount of pollutants, that is, all sectors combined over the period of fifteen years.

In 1990 a total of 8 million tonnes of air pollutants was produced in the UK which gradually decreased to 6 million tonnes in 1999 and then continued to fall to 5 million tonnes in 2005. Furthermore, the industries in the United Kingdom contributed majorly to air pollution. In 1990 alone it emitted around 6 million tonnes, but the line graph also shows that the same sector was the most significant achiever in reducing air pollution. In 2005 the emitted amount came down to only 2 million tonnes, a total reduction of 4 million tonnes approximately.

The household and transport emissions started with the exact figures in 1990. However, there was a slight increase and a subsequent decrease for the transport sector in the middle with a total rise since 1999 to 3 million tonnes in 2005. The household sector brought down its contribution to air pollution since 1999 to negligible levels in 2005.
