The Center for Green Chemistry and Green Engineering at Yale, together with the UNIDO Global Green Chemistry Initiative created a descriptive and informative guide with reasons and means in which industries and governments can apply Green Chemistry. In this roadmap, you can find a background on Green Chemistry and its importance, instructions for its implementation, references, technical information, and case studies. The Yale-UNIDO Guide to Green Chemistry can be accessed at: https://www.global-green-chemistry-initiative.com/guidance-document
