It should be noted that improved data sources and estimation techniques have routinely led to revision of historic greenhouse gas emission estimates.
'Greenhouse' gases ( GHGs) in the atmosphere help to retain radiation, resulting in warming of the lower atmosphere and earth surface. The process, known as the greenhouse effect, is essential to maintain global temperatures that sustain life on earth. Atmospheric concentrations of GHGs have increased as a result of human activities since the industrial revolution (c.1750). This has enhanced the greenhouse effect.
Since 1990 (1995 for the F-gases, i.e. hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride) net greenhouse gas emissions in Scotland have reduced by 15.4% and in 2005 equalled 54.6 million tonnes of carbon dioxide equivalent.
In 2007, the Scottish Government set purpose targets, to reduce emissions by 2011 and a further target, to reduce emissions by 80% by 2050.
