Climate change caused by human activities that emit greenhouse gases into the air has started showing its
affect in the frequency of extreme weather events such as drought, extreme temperatures, flooding, high
winds;and severe storms. Global surface temperature has also increased between the start and the end of
the 20th century, caused by increasing concentrations of greenhouse gases resulting from Fossil fuels
burning and deforestation;
With the increasing attention given to the link between greenhouse gases and climate change, many
companies are quantifying their greenhouse gases emissions for internal management purposes and an
increasing number are also preparing a greenhouse gas statement:
(a) As part of a regulatory disclosure regime;
(b) As part of an emissions trading scheme or
(c) To inform investors and others on a voluntary basis, included as part of annual report.
