Introduction: Among other places, the International System of Quantities (ISQ) will be utilized in textbooks and instruction, scientific and engineering publications, conference proceedings and papers, and industry.The International Organization for Standardization publishes the 13-part ISO 80000 Quantities and Units standard, which includes the names of quantities along with their symbols and units.The majority of the components are made up of mathematics and the natural sciences, including physics, light and radiation, acoustics, physical chemistry, atomic and nuclear physics, and condensed matter physics. Furthermore discussed are characteristic numbers and a few technical specialties, including mechanics, thermodynamics, and electromagnetic. The International System of Units (SI) serves as the basis for the units. Regretfully, the standard does not address chemical and process engineering, environmental engineering, or engineering economics. . This article suggests adding them to the ISO standard under the provisional heading of “Chemical and Environmental Engineering.” The standard is proposed to include the following additional sections: (a) reaction and separation engineering along with mass transfer and reaction kinetics; (b) process design, control, and optimization; (c) process economics, mathematical modeling, and operational research; and (d) environmental engineering with regard to pollution reduction, climate change, resource efficiency, zero waste, and the circular economy. Approximately 70 pieces, or the average of ISO 80000 parts, are planned but not required. The SI unit, the quantity name and definition (with an equation if applicable), and the notes (running number will be added later) are all included in each quantity item. The standards are outlined in ISO 80000-1 General Rules, and the other ISO 80000 parts’ practices are followed; the amounts that are already mentioned in the other parts are not duplicated. The Green Book guidelines of the International Union of Pure and Applied Chemistry (IUPAC) are also followed. Traditional textbooks, encyclopedias, and handbooks from the environmental and chemical engineering disciplines were among the works consulted. The following list includes some typical errors made while printing quantity and unit symbols.

Keywords: chemical; environmental; engineering; quantities; standard; symbols; units.
