Green Chemistry also known as “clean Chemistry” or “sustainable Chemistry”, has emerged as an important tool for meeting the major challenges of global sustainability. Innovations and applications of Green Chemistry in education have helped companies not only benefit environmentally but at the same time achieve economic and societal goals also. As education is the forerunner of implementation, a student must be trained to apply Chemistry in a greener way. An introductory text on Green Chemistry is designed as a textbook for discipline specific elective course (DSE) on the subject. This book is written with an objective to introduce the concept of Green Chemistry to undergraduate students.
