The graph illustrates the amount of acid rain emissions, measured in millions of tonnes, produced by four different sectors in the UK from 1990 to 2007.
Overall, all sectors showed a decline in acid rain emissions over the period. The electricity, gas and water supply sector experienced the most significant drop, while the domestic sector had the smallest change.
In 1990, the electricity, gas and water supply sector emitted the highest amount of acid rain at just over 3 million tonnes. This figure fell sharply to below 1 million tonnes by 2007. Similarly, emissions from the ‘other industries’ category started at around 2 million tonnes and dropped steadily to about 1.2 million tonnes in 2007.
Transport and communication began with just under 1 million tonnes in 1990, fluctuated slightly over the years, and ended at around 0.6 million tonnes. The domestic sector produced the least emissions throughout the period, remaining relatively stable, decreasing slightly from about 0.6 to 0.3 million tonnes.
In summary, acid rain emissions from all sectors declined between 1990 and 2007, with the most dramatic decrease seen in the electricity, gas and water supply sector.
