The line graph illustrates the acid rain emissions in the UK, measured in millions of tonnes, from 1990 to 2007 across four different sectors.
Overall, all sectors experienced a downward trend, except for the transport and communication sector.At the beginning of the period, the largest amount of acid rain emissions came from the electricity, gas, and water supply sector. However, by the end of the period, this sector had fallen to third place. The domestic sector consistently showed negative changes throughout, starting and ending with the lowest levels of acid rain emissions.
In 1991, the transport and communication sector had emissions similar to the domestic sector, with approximately 0.7 and 0.6 million tonnes, respectively. The electricity, gas, and water supply sector, along with other industries, started with around 3.3 and 2.1 million tonnes. Between 1993 and 1995, all sectors, except for transport and communication, began to show a decline in emissions.
By 2007, acid rain emissions in the electricity, gas, and water supply sector had significantly decreased, from about 1.8 million tonnes in 1995 to 0.5 million tonnes by the end of the period. Despite the overall negative trend, the transport and communication sector fluctuated and ended up in the same position it held at the beginning of the period. In contrast, other industries and domestic acid rain emissions decreased by approximately 1.3 and 0.3 million tonnes, respectively.
