I will be talking on "Learning to lower costs and carbon emissions with ICT" at the ACS Victorian Branch 2009 Conference, 15 May 2009. In this I am arguing that applications such as the Moodle e-learning and Mahara ePortfolio/social networking can reduce carbon emissions. These tools replace travel and classrooms for education and so reduce the carbon footprint of education. Also they teach the students how to work this way, so that in their workplace they can replace meetings and meeting rooms with web based tools.
I find online tools very useful for business, but the impediment is to find people to work with who are able to use them effectively. The idea that young people just naturally learn to use the web is a myth; they still need to be trained on how to use it effectively. Even IT professionals, who know how the tools work, do not use them effectively unless shown how.
Another example of using the web for CO2 reduction I will use for the conference is getting there. I have been using the web for "Finding a green way to get to a green conference". So far I have managed to find trains from Melbourne to Ballarat, with a side trip to Box Hill Institute to discuss vocational sustainability training for computing students.
