We are delighted to share with you that Thomson Reuters has announced that the initial impact factor for ACS Sustainable Chemistry & Engineering (ACS SCE) is 4.64. This impact factor is calculated as the average number of times that articles published in Volume 1 of our journal (articles published in 2013) were cited in journals tracked by Thomson Reuters during 2014. Next year, our impact factor will be the average number of times that articles published in Volumes 1 and 2 of our journal are cited in 2015. We are grateful to our many worldwide authors and reviewers for their valuable contributions in making this success possible. We also thank members of the editorial staff and the Editorial Advisory Board for their guidance and support during these foundational years.
