However, actions taken must ensure that the PSS companies that are supported are environmentally sustainable. To do this, environmental policies should be implemented by governments that indirectly benefit sustainable PSS companies that further sustainable practices. These policies include pricing mechanisms, information dissemination, reductions of transaction costs, support of environmental research efforts, and promotion of case studies.
