Foreword

The GREENS workshop provides a forum for practitioners and academics to share knowledge, ideas, practices and current results related to green and sustainable software engineering. The goal of GREENS 2012 is to discuss emerging research and the state of industrial practice, and to define a roadmap, both for academic research and for technology exchange with industry. Topics range from bringing sustainability and energy efficiency into all software lifecycle stages, to green measures and estimations, practices, notations, and tools to both greening the software engineering process, and greening the resulting ICT systems. To ensure high quality papers and presentations, all submissions were reviewed by at least three program committee members whose identity was not revealed to any of the authors. The reviewers did not review papers for which they had a conflict of interest. In particular, none of the organizers participated in the review process, and in case of direct or indirect conflict of interest they have been excluded from the selection process. Out of the 24 full paper submissions, 10 full papers and two short papers were accepted for publication and presentation at the workshop. The workshop dedicates most of its program to discussion. After a keynote and short presentations and discussions of each paper, facilitated working sessions will discuss the most interesting topics as identified by the attendees.
