Information and communications technologies are some of the fastest growing sources of CO2 emissions today, contributing from two to four percent of the world's greenhouse gases -- a figure that puts computing on par with the global aviation industry. Add to this the fact that technology use has been doubling every three to four years, and we could soon see information and communications technologies among the world's top contributors of excess greenhouse gases.
But there is good news...
There are things we can do to help.
We can use technology to reduce the impact of other less environmentally friendly activities, such as reducing travel by using web or teleconferencing for meetings.
This Green Computing Guide, prepared by Information and Communications Technology (ICT) at the U of S, shows us what we can do as a university, as students, and as staff and instructors to reduce our environmental impact when choosing, using and disposing of ICT on campus or at home.
