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]
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.
This conference, started in collaboration with the German Chemical Society (GDCh), was a major acknowledgement by IUPAC of the relevance of green chemistry. The Special Topic Issue on Green Chemistry [3] in Pure and Applied Chemistry and the starting of a Subcommittee on Green Chemistry, [4] operating in the IUPAC Division of Organic and ...
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.

The Green Chemistry Initiative of California would address transparency issues by creating a public chemical inventory and requiring more stringent regulation of chemicals that may be toxic. The CGCI Draft Report suggests a green labeling system to identify consumer products with ingredients harmful to human health and the environment.
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:
