Australia's above average temperatures force increase in Telstra's water use
Australian telecommunications company Telstra's water consumption increased by 7.5% year-on-year in 2012, mainly due to increases in data load in the network and associated use of air-conditioning.
According to the company's 2012 sustainability report, in 2012/13, Telstra used 953 mega-litres of water, equivalent to 381 Olympic-sized swimming pools, compared to 886 mega-litres in 2011/12.
More than 80% of Telstra's water consumption is used in cooling towers and due to Australia experiencing above average temperatures during summer, more air conditioning was required to keep exchanges at their optimal operating temperatures.

Reporting on its CO2 emissions, carbon emissions intensity was 0.83 tonnes CO2 equivalent per terabyte of data, a 33% decrease from the previous year and surpassing its 15% reduction target.
The company states: "We expect continued improvements in our carbon emissions efficiency due to better utilisation of network equipment and a continued dedicated investment in energy and carbon efficiency projects".
Due to significantly surpassing its goal, Telstra has set a target for a further 15% reduction in emissions intensity in 2013/14.
