The provided chart depicts the amount of acid rain emissions in the United Kingdom, measured in millions of tonnes, categorized into four different sectors over the span of 1990 to 2007.
Overall, it is clear that a glance at the graph reveals there was a downward trend, excepting for transport and communication. It is also notable that the proportion of acid rain emissions that domestic emitted in the minority.
Commencing with electricity, gas and water supply, it is noticeable that it has the highest data at around 3.4 million tonnes by 1991, followed by shrinking considerably to approximately 1.3 million tonnes over the following six years. Subsequently, it continuously decelerated sequentially to precisely 0.5 in the final year. Conversely, the figure for transport and communication witnessed a leveling off at around 0.75 million tonnes between 1991 and 1999, before accelerating slightly to surpass the data of electricity, gas, and water supply in 2003 and reverted back to the initial 0.75 by the end of the period.
Concerning the two remaining sectors, through the first two years, starting from 1991, the rate of acid rain emissions emitted by other industries remained stable at nearly 2.1 million tonnes. Following that, it declined gradually to roughly 1.25 in the end. Eventually, because of experiencing a steady decrease from about 0.6 to around 0.2 million tonnes from 1991 to 2007, the rate of domestic plateau was the lowest throughout and becoming the sector emitted the acid rain emissions at least in the UK.
