The UK emissions of chemicals that can cause acid rain decreased by 12.4 per cent in 2009, compared with 2008, to 2.2 million tonnes – the lowest level since records began in 1990. This breaks down as follows:
emissions from the UK companies and the public sector decreased by 12.1 per cent to 2.0 million tonnes
emissions from households decreased by 15.8 per cent to 0.2 million tonnes
Emissions of chemicals that can cause acid rain from the non-household sector accounted for 91.4 per cent of total acid rain emissions in 2009. This was mainly due to emissions from transport and communication industries; agriculture, forestry and fishing; electricity, gas and water industries; and manufacturing industries, which together accounted for 89.6 per cent of the non-household sector.
Emissions from the non-household sector decreased by 0.3 million tonnes in 2009, compared with 2008, primarily due to a fall in emissions from the transport and communication industry; manufacturing industry; and electricity, gas and water industry. Emissions by these industries decreased by 0.3 million tonnes in 2009, mainly due to a fall in Nitrogen Oxides ( NOX ) and Sulphur Dioxide (SO2). The manufacturing industry recorded the largest percentage fall (17.5 per cent) in emissions in 2009, compared with 2008, partly due to a fall in the economic activity.
A sharp fall, 67.4 per cent, in acid rain emissions from the non-household sector between 1990 and 2009, mainly reflects the move away from coal towards nuclear generated electricity and gas fired plants.
Emissions of chemicals that can cause acid rain from the household sector decreased in 2009, compared with 2008, mainly due to a fall in Nitrogen Oxides ( NOX ) and Sulphur Dioxide (SO2). Emissions caused by Nitrogen Oxides ( NOX ) fell by 22.6 per cent, and emissions caused by Sulphur Dioxide (SO2) fell by 10.1 per cent.
Emissions from the household sector decreased by 68.6 per cent to 0.2 million tonnes between 1990 and 2009. The main source for this fall was Nitrogen Oxides ( NOX ), which fell by 76.6 per cent during this period.
