There are ambiguities in the definition of green chemistry and how it is understood among broader science, policy, and business communities. Even within chemistry, researchers have used the term "green chemistry" to describe a range of work independently of the framework put forward by Anastas and Warner (i.e., the 12 principles). [12]
It uses existing principles of green chemistry and green engineering [3] to make nanomaterials and nano-products without toxic ingredients, at low temperatures using less energy and renewable inputs wherever possible, and using lifecycle thinking in all design and engineering stages.
Green solvents are environmentally friendly chemical solvents that are used as a part of green chemistry. They came to prominence in 2015, when the UN defined a new sustainability -focused development plan based on 17 sustainable development goals, recognizing the need for green chemistry and green solvents for a more sustainable future.

A green source for photocatalyst synthesis refers to a material that is renewable, biodegradable, and has minimal environmental impact during its extraction and processing. [3] [4] This approach aligns with the principles of green chemistry, which aim to reduce or eliminate the use and generation of hazardous substances in chemical processes.
John Charles Warner (born October 25, 1962) is an American chemist, educator, and entrepreneur, best known as one of the founders of the field of green chemistry.Warner worked in industry for nearly a decade as a researcher at Polaroid Corporation, before moving to academia where he worked in various positions at University of Massachusetts Boston and Lowell.

Paul T. Anastas (born May 16, 1962, in Quincy, Massachusetts) [1] is an American scientist, inventor, author, entrepreneur, professor, and public servant. He is the Director of Yale University's Center for Green Chemistry and Green Engineering, [2] Previously he served as the Science Advisor to the United States Environmental Protection Agency [3] as well as the Agency's Assistant ...
Green chemistry is the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances. [1] Green chemistry is based upon twelve principles, identified in “Green Chemistry: Theory and Practice” and adopted by the US Environmental Protection Agency (EPA). [2]
The first general metric for green chemistry remains one of the most flexible and popular ones. Roger A. Sheldon’s environmental factor (E-factor) can be made as complex and thorough or as simple as desired and useful. [10] The E-factor of a process is the ratio of the mass of waste per mass of product:
