TABLE OF CONTENTS August 2017 Volume 12, Issue 8 Editorial Commentaries Research Highlights News and Views Perspectives Letters Articles Corrigendum In The Classroom Subscribe   Facebook   RSS   Recommend to library   Twitter   Focus Top Environmental assessment Editorial Commentaries Perspectives Engineered nanomaterials are already in use in a wide range of applications, and their everyday presence is only going to increase in the future. With such widespread potential use, the implications for the environment must be carefully evaluated to ensure that nanotechnology-enabled products are properly regulated. This special issue focuses on risk assessment and life-cycle assessment and their use in evaluating the impact of nanomaterials on the environment from different points of view. We also consider the need for stronger regulations and more effective communication about the risks posed by nanomaterials for insurance purposes. Advertisement Nature Reviews Chemistry is an online-only journal that provides both an introduction to chemists embarking on a new topic of investigation and thought-provoking, in-depth sections for the expert. The journal also publishes regular columns which focus on the teaching of chemistry and on the translation of research into business opportunities. EXPLORE THE JOURNAL NOW   Editorial Top Joining forces   p713 doi:10.1038/nnano.2017.169 Risk assessment and life-cycle assessment provide complementary information on the impact of a technology on the environment. We present diverging opinions on how to integrate the two approaches to best evaluate the environmental impact of engineered nanomaterials. Commentaries Top React now regarding nanomaterial regulation   pp714 - 716 Steffen Foss Hansen doi:10.1038/nnano.2017.163 The time has come to implement a regulatory framework tailored to manufactured materials. I propose a new legislative framework that combines registration, evaluation, authorization and categorization of nanomaterials. Insuring nanotech requires effective risk communication   pp717 - 719 Finbarr Murphy, Martin Mullins, Karena Hester, Allen Gelwick, Janeck J. Scott-Fordsmand and Trevor Maynard doi:10.1038/nnano.2017.162 The absence of nanotechnology-specific insurance policies could be detrimental to the development of the nanotechnology industry.
