Green chemistry is also commonly termed as sustainable chemistry and is a chemical thought dedicated to designing environmentally friendly products that would reduce the use of hazardous materials in industrial settings. Green chemistry is often confused with environmental chemistry which is the study of the harmful pollutants found in the natural environment. Whereas green chemistry is particularly concerned with reducing these chemical pollutants by identifying the sources and then developing innovative plans to reduce them. Green chemistry is an interdisciplinary sub-field of chemistry which utilizes concepts from many sub-fields such as inorganic chemistry, organic chemistry, analytical chemistry, biochemistry and to some extent analytical chemistry as well. Green chemistry is solely confined to applications in industrial setting pollutant sources. Click chemistry an associated philosophy in green chemistry is a common theory used in reaching ultimate aims of green chemistry that is through chemical synthesis.

Term papers on green chemistry often require students to apply the click chemistry to industrial sources to achieve effectual chemical performance by reducing its harmful nature. This concept clearly draws a line between green chemistry and environmental chemistry which only focuses on the naturally occurring chemical processes. Research papers in green chemistry often tend to focus upon the applications of the most recent developments in this field of chemistry such as supercritical carbon dioxide use in place of green solvent and the utilization of hydrogen in asymmetric synthesis process and also the used of aqueous hydrogen peroxide for more cleaner oxidation processes.
