The Current Opinion journals were developed out of the recognition that it is increasingly difficult for specialists to keep up to date with the expanding volume of information published in their subject. In Current Opinion in Green and Sustainable Chemistry, we help the reader by providing in a systematic manner: The views of experts on current advances in Green and Sustainable Chemistry in a clear and readable form.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.Division of the subject into sections The subject Green and Sustainable Chemistry includes all chemical aspects along the life cycle of chemicals as well chemical products and materials e.g. resources, synthesis, use and after life issues. It aims on better understanding where and how chemistry itself can be made more sustainable and whereby chemistry can contribute to sustainability in general. Therefore, the journal it is divided into themed sections, each of which is reviewed once a year. The amount of space devoted to each section is related to its importance:Mineral and fossil resources and metalsBiomass, bio-fuels and bioenergiesCO2 capture, and chemistryGreen solventsGreen catalysisNew synthetic methodsPhotocatalysisGreen processes and technologiesRenewable energy and storageSustainable recycling of molecules, materials and productsBenign by DesignNew business models, ethics, legislation and economicsThere is also a section that changes every year to reflect hot topics in the field.Selection of topics to be reviewed Section Editors, who are major authorities in the field, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission reviews from authorities on each topic that they have selected.Reviews Authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.Editorial Overview Section Editors write a short overview at the beginning of the section to introduce the reviews and to draw the reader's attention to any particularly interesting developments.
