The Chemistry Society is now working on developing novel chemistry that is less hazardous to the environment and human health. Green chemistry, ecologically friendly chemistry, clean chemistry, and atom economy are some of the terms used to describe this innovative approach. There has been progress toward practicing chemistry using facts that go beyond the qualities of the target chemical or the efficacy of certain solvents or reagents. Green chemistry is the practice of chemistry in such a manner that it optimizes its advantages while minimizing its negative impacts. It focuses on ways for reducing the usage of dangerous items or by-products, as well as their creation. Several chemical industries are now the most polluting to the environment. As a result, efforts have been made to create and develop synthetic ways for manufacturing procedures that produce the fewest waste products, have no impact on the environment, and are easy to dispose of. Some pharmaceuticals create a large quantity of waste or by-products during their manufacture in the pharmaceutical industry, resulting in a low yield in the final goods. The reactant or starting materials, reagents, solvents, and catalysts must all be carefully chosen while executing chemical reactions. Green chemistry is crucial in pharmaceutical chemistry for the development of new medications that are less toxic, more effective, and have fewer adverse effects. In today's agriculture, green chemistry has become the new norm. Sustainable agriculture and green chemistry are two cutting-edge topics that are inextricably linked. At this time, the utilization of renewable biomass resources is increasing in agriculture to generate bio-based food products with low inputs, zero waste, significant social value, and reduced environmental effects. The purpose of this paper is to analyze and clarify the notion of green chemistry, as well as its implications for environmental sustainability.
