Green chemistry accentuates how important it is to building the future. In this paper an overview on applicability of 12 Principles of green chemistry, applicability is covered, along with their developments and some applications are discussed. Key words: Green Chemistry, Green Principle, Green Synthesis and Green Solvents Introduction Green Chemistry has spent the last two decades. It is a way of thinking about present and emerging tools, knowledge, and chemistry design in order to contribute to society's economy while protecting the environment and human health. Green chemistry is a trend that will persist. "Green chemistry efficiently uses raw resources (ideally renewable ones), reduces waste, and forgoes the use of hazardous and/or toxic reagents and solvents in the production and use of chemical products. The design of eco-friendly products and processes (benign by design), as established by Paul Anastas and John Warner, serves as the guiding concept. The Twelve Principles of Green Chemistry are as represent step by steps [1, 2] i) Prevention, ii) Atom Economy, iii) Less Hazardous Chemical Syntheses, iv) Designing Safer Chemicals, v) Safer Solvents and Auxiliaries, vi) Design for Energy Efficiency, vii) Use of Renewable Feedstocks, viii) Reduce Derivatives, ix) Catalysis, x) Design for Degradation, xi) Real-time analysis for Pollution Prevention, xii) Inherently Safer Chemistry for Accident Prevention. These guidelines offer a comprehensive framework for scientists, engineers, and researchers to create novel solutions that not only satisfy the needs of contemporary society but also drastically lessen the environmental impact of chemical processes. The Renowned 12 Principles of Green Chemistry Green chemistry examines how chemical products and the methods used to make them affect the environment. The objective is to create a green process to produce the product, which is a given. Green chemistry is a fundamental form of pollution prevention rather than waste remediation since it eliminates waste at the source. The primary tenet of green chemistry is that prevention is preferable to cure. Sustainable Technologies is a different word that is currently preferred by the chemical industry. Green Chemistry is the means to achieving sustainability, according to some. For better understanding of the principles of green chemistry [2-5] and some examples of their applications to basic and applied research are illustrated below: 1. Prevention One of the most well-known rules for process optimization refers to scientists' ability to rework chemical reactions to reduce the production of hazardous waste as a crucial step in the avoidance of pollution. The risks connected with garbage storage, transportation, and treatment could be reduced by minimizing waste generation. This idea is simple to comprehend and straightforward to put into practice, and examples from both business and academics have demonstrated its importance, applicability, and viability. This tenet of green chemistry is still true, but we need to think about it differently, moving away from a narrow definition of waste based on its quantity and toward a more inclusive strategy: (i) we need to consider the multidimensionality of trash. (ii) The "amount of waste per quantity of product" paradigm needs to give way to one that addresses the "quantity of waste generated per function given by the product." In this way, we must strive to improve both product quality and functionality. (iii) When considering a product's whole life cycle, we must take into account the fact that waste is produced not only during the production process but also after the product has
