The line graph compares four sectors in terms of the amount of acid rain emissions that they produced over a period of 17 years in the UK.
It is clear that the total amount of acid rain emissions in the UK fell considerably between 1990 and 2007. The most dramatic decrease was seen in the electricity, gas and water supply sector.
In 1990, around 3.3 million tonnes of acid rain emissions came from the electricity, gas and water sector. The transport and communication sector was responsible for about 0.7 million tonnes of emissions, while the domestic sector produced around 0.6 million tonnes. Just over 2 million tonnes of acid rain gases came from other industries.
Emissions from electricity, gas and water supply fell dramatically to only 0.5 million tonnes in 2007, a drop of almost 3 million tonnes. While acid rain gases from the domestic sector and other industries fell gradually, the transport sector saw a small increase in emissions, reaching a peak of 1 million tonnes in 2005.
