UN sustainable development goals: How can sustainable/green chemistry contribute? By doing things differently (2018)
Journal Article
Poliakoff, M., Licence, P., & George, M. W. (2018). UN sustainable development goals: How can sustainable/green chemistry contribute? By doing things differently. Current Opinion in Green and Sustainable Chemistry, 13, 146-149. https://doi.org/10.1016/j.cogsc.2018.04.011

Until now, much Green and Sustainable Chemistry has been focused on how chemicals are made. Here we suggest that, if chemistry is to contribute effectively to achieving the SDGs, we need to change the way that things are done at both ends of the chem...
