Thanks to computational trust engines, it is possible to: 1) foster collaboration between all these stakeholders and allow them to collaborate together in a sound and trustworthy manner, and 2) promote technologies that are more sustainable by assessing and selecting them thanks to pervasively deployed trust engines. In this article we depict techniques based on public key infrastructures and trust engines to differentiate eco-computing from more polluting computing in a trustworthy way. The environment is only one of the dimensions where trust engines can foster sustainability. 收起
