This paper from Climate Risk Pty Ltd in Australia was commissioned by Telstra, a communications provider in Australia, to investigate the benefits of telecommunications in reducing carbon usage and the deleterious effects of greenhouse gas emissions. Examples of savings are described, such as telecommunications to control appliance energy usage in standby mode or when a user is not present. Telecommuting or commuting to a nearby regional office is another savings opportunity, as is teleconferencing. An overview of global warming is included. It was noted that telecommunications equipment contributes to greenhouse gasses by using power for operations and for cooling. On balance, telecommunications could reduce 4.9 per cent of greenhouse gas emissions in Australia.
