The Australian company, Digital Pacific was founded in Sydney in 2000. They are a profitable, consumer oriented organization that provides a range of hosting and web services to corporate organizations and consumers.
Recently Digital Pacific pledged to make quarterly reviews of their carbon footprint in order to estimate emissions from all aspects of its business including regular daily operation and maintenance of hosting servers, routers and air conditioners that cool the servers.

After each review, the company plans to buy carbon credits to cover 100% of its total estimated emissions. This will ensure that however much power Digital Pacific uses each quarter, the equivalent amount will be fed back into the grid via solar or wind power instead of other non-sustainable means.
