AUSTRALIA IT , the amount of value that Fujitsu can add becomes apparent . His conversations with clients these days have moved up to board level as the reputational and financial gains to be made are made clear . But like charity , sustainability begins at home . Fujitsu has more than 100 data centres round the world . Six of these are in Australia , and the company has been among the first to grasp the energy nettle .
Fujitsu ’ s 17,500 square metres of data centre space accounts for 97 percent of the company ’ s greenhouse gas emissions . The data centres accommodate Fujitsu ’ s own servers and cloud infrastructure as well as a large amount of space dedicated to colocation services . Each of the data centres uses as much power as a small sized town .
Sustainability - a global imperative Most of the power available in Australia is generated from coal : renewable alternatives are making inroads but the electricity they generate is still more costly . Basically , most of Australian power is ‘ dirty power ’. Stewart tells how even his thinking , driven by a passion for sustainable development as it already was , was given a jolt at the Asia-Pacific Energy Leaders ’ Summit New Zealand earlier this year . “ The former Prime Minister of Kiribati Anote Tong spoke about how he has already bought land in Fiji to relocate his people . It was his speech to COP21 in Paris that swayed the adoption of a 1.5-degree target for global warming when he explained that even that would not be enough to save his entire country , which is only just above sea level , from being swamped .
Inspired by Anote Tong ’ s words he wants to drive forward an initiative that has been dear to his heart from day one . “ When I took this role over five years ago our data centre managers were doing very good work but what I found frustrating was that the power use effectiveness ( PUE ) metric that we use in our industry was not being applied transparently .”
PUE measures the ratio between the total power used by the data centre and the energy delivered to run
