The line graph illustrates the proportion of acid rain produced in millions of tonnes in the UK from four categories between the years 1990 and 2007.
Overall, almost all sectors experienced a declining trend. Other industries and the electricity, gas, and water supply sector saw a gradual fall in acid rain emissions. Meanwhile, transport and communication underwent a steady rise until 2005; afterwards, it dipped until 2007. Moreover, the domestic industry had a slight decrease with a steady pattern.
Firstly, electricity, gas, and water supply started at about 3.25 million tonnes as the highest producer of acid rain in 1990, but fell gradually by a significant amount until 1999 and then dropped steadily until 2007, until it reached 0.5 million tonnes. Furthermore, other industries stood at just above 2 million tonnes for the initial three years until a gradual decline until 2007, where this category stood as the top contender in producing acid rain.
Lastly, the remaining two industries started at just over 0.5 million tonnes, where transport and communication steadily increased until it reached a peak of 1 million tonnes and then dropped by one-fourth of a million tonnes by 2007. Additionally, the domestic sector remained unchanged for the first 4 years until it decreased gradually to become the industry producing the least acid rain in 2007, emitting just under 0.25 million tonnes of acid rain.
