UK 'acid rain' precursor emissions, Million tonnes of sulphur dioxide equivalent
Emissions of chemicals that can cause acid rain fell by 52 per cent between 1990 and 2003, from 6.8 million tonnes to 3.3 million tonnes. Between 2002 and 2003 there was a slight increase of 1 per cent.
The non-domestic sector is responsible for the majority of acid rain emissions in the UK. Since 1990, emissions from these industries have fallen by 52 per cent, from 6.1 million tonnes to 3.0 million tonnes in 2003. The largest fall was in the electricity, gas and water industry where emissions fell by 72 per cent over the same period, from 3.3 million tonnes to 1.0 million tonnes.
However, between 2002 and 2003, non-domestic sector emissions rose 2.4 per cent, contributing to an increase in total emissions. Within the non-domestic sector the largest contributor to this increase was the transport and communication industry. Its emissions rose by 13 per cent from 0.8 million tonnes in 2002 to 0.9 million tonnes in 2003.
Acid rain emissions from the domestic sector fell by 55 per cent between 1990 and 2003, and fell by 11 per cent between 2002 and 2003.
